No high-temperature alert has been issued for Kerala today (Sunday). Over the past few days, the mercury has shot up, early into the season, in a few districts.
According to the Thiruvananthapuram office of the India Meteorological Department (IMD), Palakkad topped the temperature charts yesterday (Saturday) with a maximum of 37.1 degrees Celsius. This was also the highest recorded for the plains of the country as a whole for the day.

Day temperatures were above normal by 1.6-3.0 degree Celsius at most places over Punjab, Konkan and Goa, South Interior Karnataka, Kerala, and Tamil Nadu, the New Delhi office of the IMD said.


January records broken in Kerala
In Kerala, Palakkad was closely followed by Vellanikkara (Thrissur) in the neighbourhood at 36.5 degrees Celsius; Punalur and Kottayam (35.5 degrees Celsius each); Kannur (35.4 degrees Celsius) and Kozhikode (35.0 degree Celsius).
Next in the list are Alappuzha and CIAL Kochi (34.5 degree Celsius); Karipur (Kozhikode) Airport and Amini (Lakshadweep) at 34.3 degree Celsius each. The IMD does not see any possibility of major showers in Kerala during the course of this week.
Hot inland winds from the South and East are mainly responsible for the early heat, driving the mercury up from January and early into this month, which are normally categorised under winter/early spring climes.
IMD data show that five stations had recorded all-time records for hot days for the month of January, coinciding with an announcement by the National Oceanic and Atmospheric Administration (NOAA) of the US that January was the warmest in 141 years of climate record-keeping, beating the January of 2016.
The warmest year ever recorded is 2016, followed by 2019. Both, however, could be displaced if this year’s first month marks a trend, according to NOAA statistical analysis.
Back home in Kerala, Alappuzha recorded a maximum temperature of 37.3 degrees Celsius on January 25, breaking the previous record of 36.7 degrees Celsius reported on January 29, 1998. On January 23, 24, and 25 this year, Kottayam recorded 37 degrees Celsius on a trot, compared to the previous high of 36.6 degrees Celsius of January 30, 2007.


Hot winds from interior Tamil Nadu
Kannur in the North clocked 36.8 degree Celsius on January 23, breaking the previous record of 36.7 degrees Celsius of January 19, 1991. Likewise, CIAL Kochi reported a maximum temperature of 37.1 degrees Celsius on January 23 this year. The previous high was 36.1 degrees Celsius of January 30, 2017, and January 15 and 16, 2018. Vellanikkara in Thrissur reported 35.9 degrees Celsius on January 31, breaking the previous record of 35.7 degrees Celsius of January 25, 2017.
The high temperature regime in Kerala is sustained by strong hot and dry north-easterly winds blowing in from interior Tamil Nadu, mainly through the Palakkad and Punalur 'gaps' in the Western Ghats. Only evening sea breeze into land brings some relief, but limited only to areas where they can blow free.
Satellite maps clearly delineate the route for the hot easterlies - the wind stream to Palakkad is picked from as far east as Tiruchirappalli, Manapparai, Karur, Aravakurichi, Dharapuram, Tiruppur, Coimbatore, and Pollachi.
In the South, Punalur is linked to Madurai, Aruppukottai, Sattur, Kovilpatti, Kayathur and Kadayanallur. It is no accident that these gaps also feature large wind farms that tap into the steady easterly winds.
Meanwhile, the Kerala State Disaster Management Authority (KSDMA) had put out an advisory to the public to be careful against of prospects of sunburn and sunstroke. The elderly, children and pregnant women have been asked to avoid direct sunlight between 11 am and 3 pm. Schools have been advised to ensure adequate drinking water supply and keep the class rooms airy.

Uttarakhand Weather Today: Cold Returned Again Due To Rain
उत्तराखंडः रातभर पड़ी बारिश की फुहारों से लौटी ठंड, धनोल्टी, नैनीताल सहित चारों धाम में हुई बर्फबारी
न्यूज डेस्क, अमर उजाला, देहरादून Updated Fri, 21 Feb 2020 11:26 AM IST


नैनीताल में हुई सीजन की आठवीं बर्फबारी

नैनीताल में हुई सीजन की आठवीं बर्फबारी - फोटो : अमर उजाला


गरज चमक के साथ बृहस्पतिवार की रात पड़ी बारिश की फुहारों ने मौसम में एक बार फिर ठंड बढ़ा दी। इससे न्यूनतम तापमान में भी गिरावट दर्ज की गई। वहीं, शुक्रवार को हल्के बादल छाए रहने और तेज आंधी चलने की संभावना जताई गई है। मसूरी में भी रात से शुरू हुई बारिश सुबह तक रुक-रुक कर होती रही।

वहीं नैनीताल, धनोल्टी, हेमकुंड सहित चार धामों की ऊंची चोटियों पर बर्फबारी शुरू हो गई है। नैनीताल में बृहस्पतिवार रात करीब एक बजे से बारिश जारी है। वहीं आज नैनीताल शहर और ऊंची चोटियों पर इस सीजन में आठवीं बार बर्फबारी हुई है। हालांकि बारिश के कारण शहर में बर्फ रुक नहीं पाई।


चौखुटिया, लोहाघाट, हल्द्वानी, अल्मोड़ा, काशीपुर, रुद्रपुर, बाजपुर, बागेश्वर, जसपुर, भीमताल, किच्छा, रानीखेत, मुनस्यारी, पंतनगर, रामनगर सहित कुमाऊं के लगभग सभी इलाकों में रात से ही रुक-रुक कर बारिश जारी है। आज सुबह 6.30 बजे से टनकपुर-पिथौरागढ़ राष्ट्रीय राजमार्ग में मलबा आने से बेलखेत व स्वांला के पास सड़क बंद हो गई है।
कुछ इलाकों में तेज आंधी चलने का भी अनुमान
गढ़वाल में श्रीनगर, चमोली, रुद्रप्रयाग, यमुनोत्रीधाम सहित यमुना घाटी, उत्तरकाशी, नई टिहरी और आसपास के क्षेत्रों में रात से रुक-रुक कर बारिश हो रही है। चमोली और रुद्रप्रयाग की ऊंची चोटियों में बर्फबारी की संभावना है।

मौसम विभाग के मुताबिक, देहरादून समेत प्रदेश के विभिन्न क्षेत्रों में आज हल्के बादल छाए रह सकते हैं। कुछ इलाकों में तेज आंधी चलने का भी अनुमान है। मौसम केंद्र की ओर से जारी बुलेटिन के अनुसार, अगले कुछ दिन तक ऐसा ही मौसम बना रहने का अनुमान है।

देहरादून, हरिद्वार, पौड़ी, नैनीताल और ऊधमसिंह नगर जिले के कुछ इलाकों में आज भी 50 से 60 किमी प्रति घंटे की रफ्तार से आंधी चल सकती है। ऊंचाई वाले पहाड़ी क्षेत्रों में ओले गिरने का अनुमान है। मौसम केंद्र के निदेशक बिक्रम सिंह ने बताया कि अगले दो-तीन दिन कई स्थानों पर बादल छाए रहेंगे। कुछ स्थानों पर हल्की बारिश हो सकती है।
बदलता मौसम बढ़ा रहा आंखों की पीड़ा
मौसम कभी सर्द तो कभी अचानक गर्म हो रहा है। ऐसे मौसम में आंख में विभिन्न तरह की दिक्कतें होने का डर रहता है। ऐसे में डॉक्टर आंख जैसे संवेदनशील अंग का खास ख्याल रखने की जरूरत पर जोर दे रहे हैं।

नेहरू कॉलोनी, हरिद्वार रोड स्थित नवज्योति आई क्लीनिक के वरिष्ठ नेत्र रोग विशेषज्ञ डॉ. विनोद अरोड़ा ने बताया कि आजकल आंखों में एलर्जी, आंखों के लाल होने, पानी निकलने और चुभन होने के मरीज ज्यादा आ रहे हैं। इसके अलावा आजकल आंखों में खुश्की (ड्राइनस) की समस्या भी रहती है।

खासकर जो लोग वाहन चलाते वक्त चश्मा या कवर्ड हेलमेट नहीं पहनते हैं, उन्हें यह दिक्कत ज्यादा होती है। कंप्यूटर या मोबाइल स्क्रीन पर ज्यादा समय बिताने वालों की आंखों में भी ड्राइनेस की दिक्कत हो जाती है। इसी तरह आंख दुखने या आंख आने की समस्या (इंफेक्शन) की संभावना भी रहती है। आंख से चिपचिपा पदार्थ आना, लाली रहना और पानी आना इसके लक्षण हैं।


ऐसे करें बचाव
- प्रदूषण से बचने के लिए चश्मा जरूर पहनें।
- नार्मल पानी से आंखों को बीच-बीच में धोते रहें।
- दोपहिया वाहन चलाते समय चश्मा या कवर्ड हेलमेट पहनें।
- बंद चार पहिया वाहन में एसी की हवा सीधे आंखों पर न पड़े।
- ड्राइनेस की समस्या होने पर डॉक्टर की सलाह से अच्छे ल्यूब्रिकेंट्स (आई ड्रॉप) का इस्तेमाल करें।
- आंख आना फैलने वाली बीमारी है। यह किसी भी व्यक्ति के संपर्क में आने से हो जाती है। इसलिए अगर घर में किसी को यह दिक्कत हो तो उनका तौलिया, रुमाल आदि बिना धुले इस्तेमाल न करें।
- आंख में कोई भी ड्राप बिना विशेषज्ञ डॉक्टर की सलाह के न डालें और न ही कोई दवा लें। किसी भी तरह दिक्कत होने पर तुरंत विशेषज्ञ डॉक्टर को दिखाएं।

Mild tremors felt in Assam, Nagaland - Eastern Mirror

easternmirrornagaland.com

Feb 23, 2020 10:33 PM

Guwahati, Feb. 23 (IANS): Two separate mild earthquakes with a magnitude 2.8 to 3.4 hit some parts of Assam and Nagaland on Sunday. There was no report of any damage or casualty, an official said.

According to the official of the India Meteorological Department (IMD) the first quake with a magnitude of 3.4 on the Richter scale hit Wokha in western Nagaland at 5.12 am.

The IMD official said that another tremor with a magnitude of 2.8 on the Richter scale hit Tezpur in northern Assam at 5.35 am.

The two tremors, which lasted a few seconds, were measured at 28 to 30 km depths of the earth.

According to the IMD observations, at least 27 separate moderate and mild shakes struck this month in different Northeastern states — Assam , Arunachal Pradesh, Manipur, Meghalaya, Mizoram and Nagaland and areas bordering Myanmar and Bangladesh.

Seismologists consider India’s mountainous Northeast region as the sixth major earthquake-prone belt in the world.

The Northeast has seen some of the biggest earthquakes in history.

In 1897, a Shillong-epicentred quake measured 8.2 on the Richter scale, while in 1950, an earthquake in Assam measuring 8.7 on the Richter Scale forced the Brahmaputra river to change its course.

Fog in North India normally happens
when temperature drops near 9 Degree Celcius with humidity crossing 80% approx. around water bodies.



Fog screens out chill
Experts say fog occurs when the
air becomes saturated with moisture and the
temperature is less than the dew point —
the temperature at which water vapour in a volume of humid air condenses into water.

“Higher the temperature, higher the capacity of the air to hold water vapour. So when the temperature drops, at dawn or in the evening, there tends to be fog,” said a weather department official.








Fog - Wikipedia, the free encyclopedia
Definition
The term "fog" is typically distinguished from the more generic term "cloud" in that fog is low-lying, and the moisture in the fog is often generated locally (such as from a nearby body of water, like a lake or the ocean, or from nearby moist ground or marshes).[2]

By definition, fog reduces visibility to less than 1 kilometre (0.62 mi), whereas mist causes lesser impairment of visibility.[3]

For aviation purposes in the UK, a visibility of less than 5 kilometres (3.1 mi) but greater than 999 metres (3,278 ft) is considered to be mist if the relative humidity is 70% or greater; below 70%, haze is reported.[4][broken citation]





Formation
See also: Cloud physics
Fog forms when the difference between air temperature and dew point is generally less than 2.5 °C or 4 °F.[5]

Fog begins to form when water vapor condenses into tiny liquid water droplets suspended in the air. The main ways water vapor is added to the air: wind convergence into areas of upward motion;[6] precipitation or virga falling from above;[7] daytime heating evaporating water from the surface of oceans, water bodies, or wet land;[8] transpiration from plants;[9] cool or dry air moving over warmer water;[10] and lifting air over mountains.[11] Water vapor normally begins to condense on condensation nuclei such as dust, ice, and salt in order to form clouds.[12][13] Fog, like its elevated cousin stratus, is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass.[14]

Fog normally occurs at a relative humidity near 100%.[15] This occurs from either added moisture in the air, or falling ambient air temperature.[15] However, fog can form at lower humidities, and fog can sometimes fail to form with relative humidity at 100%. A reading of 100% relative humidity means that the air can hold no additional moisture; the air will become supersaturated if additional moisture is added.

Fog can form suddenly, and can dissipate just as rapidly, depending whether the temperature is below or above the dew point, respectively. The sudden formation of fog is known as "flash fog".[16]

Fog commonly produces precipitation in the form of drizzle or very light snow. Drizzle occurs when the humidity of fog attains 100% and the minute cloud droplets begin to coalesce into larger droplets.[17] This can occur when the fog layer is lifted and cooled sufficiently, or when it is forcibly compressed from above by descending air. Drizzle becomes freezing drizzle when the temperature at the surface drops below the freezing point.

The thickness of a fog layer is largely determined by the altitude of the inversion boundary, which in coastal or oceanic locales is also the top of the marine layer, above which the airmass is warmer and drier. The inversion boundary varies its altitude primarily in response to the weight of the air above it which is measured in terms of atmospheric pressure. The marine layer and any fogbank it may contain will be "squashed" when the pressure is high, and conversely, may expand upwards when the pressure above it is lowering.





Types
Fog can form in a number of ways, depending on how the cooling that caused the condensation occurred.

Radiation fog is formed by the cooling of land after sunset by thermal radiation in calm conditions with clear sky. The cool ground produces condensation in the nearby air by heat conduction. In perfect calm the fog layer can be less than a meter deep but turbulence can promote a thicker layer. Radiation fogs occur at night, and usually do not last long after sunrise, though can persist all day in the winter months especially in areas bounded by high ground such as the Vale of York in England. Radiation fog is most common in autumn and early winter. Examples of this phenomenon include the Tule fog.[18]

Ground fog is fog that obscures less than 60% of the sky and does not extend to the base of any overhead clouds.[19] However, the term is usually a synonym for radiation fog.


Advection fog layer in San Francisco with the Golden Gate Bridge and skyline in the background
Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled.[20] It is common as a warm front passes over an area with significant snow-pack. It is most common at sea when moist air encounters cooler waters, including areas of cold water upwelling, such as along the California coast (see San Francisco fog).

The advection of fog along the California coastline is propelled onto land by one of several processes. A cold front can push the marine layer coast-ward, an occurrence most typical in the spring or late fall. During the summer months, a low pressure trough produced by intense heating inland creates a strong pressure gradient, drawing in the dense marine layer. Also during the summer, strong high pressure aloft over the desert southwest, usually in connection with the summer monsoon, produces a south to southeasterly flow which can drive the offshore marine layer up the coastline; a phenomenon known as a "southerly surge", typically following a coastal heat spell. However, if the monsoonal flow is sufficiently turbulent, it might instead break up the marine layer and any fog it may contain. Moderate turbulence will typically transform a fog bank, lifting it and breaking it up into shallow convective clouds called stratocumulus.

Precipitation fog (or frontal fog) forms as precipitation falls into drier air below the cloud, the liquid droplets evaporate into water vapor. The water vapor cools and at the dewpoint it condenses and fog forms.

Hail fog sometimes occurs in the vicinity of significant hail accumulations due to decreased temperature and increased moisture leading to saturation in a very shallow layer near the surface. It most often occurs when there is a warm, humid layer atop the hail and when wind is light. This ground fog tends to be localized but can be extremely dense and abrupt. It may form shortly after the hail falls; when the hail has had time to cool the air and as it absorbs heat when melting and evaporating.[21]





Freezing conditions
Freezing fog occurs when liquid fog droplets freeze to surfaces, forming white soft or hard rime.[22] This is very common on mountain tops which are exposed to low clouds. It is equivalent to freezing rain, and essentially the same as the ice that forms inside a freezer which is not of the "frostless" or "frost-free" type. The term "freezing fog" may also refer to fog where water vapor is super-cooled, filling the air with small ice crystals similar to very light snow. It seems to make the fog "tangible", as if one could "grab a handful".

Frozen fog (also known as ice fog) is any kind of fog where the droplets have frozen into extremely tiny crystals of ice in midair. Generally this requires temperatures at or below −35 °C (−31 °F), making it common only in and near the Arctic and Antarctic regions.[23] It is most often seen in urban areas where it is created by the freezing of water vapor present in automobile exhaust and combustion products from heating and power generation. Urban ice fog can become extremely dense and will persist day and night until the temperature rises. Extremely small amounts of ice fog falling from the sky form a type of precipitation called ice crystals, often reported in Barrow, Alaska. Ice fog often leads to the visual phenomenon of light pillars.

The phenomenon is also extremely common in the inland areas of the Pacific Northwest, with temperatures in the 10 to 30 °F (−12 to −1 °C) range. The Columbia Plateau experiences this phenomenon most years due to temperature inversions, sometimes lasting for as long as three weeks. The fog typically begins forming around the area of the Columbia River and expands, sometimes covering the land to distances as far away as LaPine, Oregon, almost 150 miles (240 km) due south of the river and into south central Washington.





Topographical influences
Up-slope fog or hill fog forms when winds blow air up a slope (called orographic lift), adiabatically cooling it as it rises, and causing the moisture in it to condense. This often causes freezing fog on mountaintops, where the cloud ceiling would not otherwise be low enough.

Valley fog forms in mountain valleys, often during winter. It is essentially a radiation fog confined by local topography, and can last for several days in calm conditions. In California's Central Valley, valley fog is often referred to as Tule fog.





Sea and coastal fog
Sea fog (also known as haar or fret) is heavily influenced by the presence of sea spray and microscopic airborne salt crystals. Clouds of all types require minute hygroscopic particles upon which water vapor can condense. Over the ocean surface, the most common particles are salt from salt spray produced by breaking waves. Except in areas of storminess, the most common areas of breaking waves are located near coastlines, hence the greatest densities of airborne salt particles are there.

Condensation on salt particles has been observed to occur at humidities as low as 70%, thus fog can occur even in relatively dry air in suitable locations such as the California coast. Typically, such lower humidity fog is preceded by a transparent mistiness along the coastline as condensation competes with evaporation, a phenomenon that is typically noticeable by beachgoers in the afternoon. Another recently discovered source of condensation nuclei for coastal fog is kelp seaweed. Researchers have found that under stress (intense sunlight, strong evaporation, etc.), kelp releases particles of iodine which in turn become nuclei for condensation of water vapor, causing fog that diffuses direct sunlight.[24]

Sea smoke, also called steam fog or evaporation fog, is the most localized form and is created by cold air passing over warmer water or moist land.[22] It often causes freezing fog, or sometimes hoar frost.

Arctic sea smoke is similar to sea smoke, but occurs when the air is very cold. Instead of condensing into water droplets, the water vapor desublimates directly into ice crystals.

Garua fog near the coast of Chile and Peru,[25] occurs when typical fog produced by the sea travels inland, but suddenly meets an area of hot air. This causes the water particles of fog to shrink by evaporation, producing a "transparent mist". Garua fog is nearly invisible, yet it still forces drivers to use windshield wipers because of deposition of liquid water on hard surfaces.





Biological effects and human uses
Redwood forests in California receive approximately 30-40% of their moisture from coastal fog. Change in climate patterns could result in relative drought in these areas.[26] Some animals, including insects, depend on wet fog as a principal source of water, particularly in otherwise desert climes, as along many African coastal areas. Some coastal communities use fog nets to extract moisture from the atmosphere where groundwater pumping and rainwater collection are insufficient.

Armies have advanced under fog to hide their movements from the opposing forces.[citation needed]

Artificial fog is man-made fog that is usually created by vaporizing a water and glycol-based or glycerine-based fluid. The fluid is injected into a heated block, and evaporates quickly. The resulting pressure forces the vapor out of the exit. Upon coming into contact with cool outside air, the vapor condenses in microscopic droplets and appears as fog.

Weather Forecast: भारी बारिश के साथ गिरेंगे ओले, मौसम विभाग ने इन राज्यों में जारी किया Alert


Snowfall and Rain देश के कई राज्यों में भारी बारिश के साथ बर्फबारी हो रही है। मौसम विभाग ने कई जगहों पर अलर्ट भी जारी किया है। वहीं अब बारिश होने से फसल को भी नुकसान पहुंच रहा है


नई दिल्ली, एजेंसियां। हाल ही में शिवरात्रि के दिन मौसम में बदलाव देखने को मिला था, लेकिन उससे पहले भी और अब बाद में भी गर्मी का दौर आता देखा जा सकता है। फरवरी का महीना चल रहा है और अभी से ही धूप इतनी तेज है कि लोगों को गर्मी का एहसास होने लगा है। सबके मन में एक ही सवाल है कि अगर अभी से ही ये हाल है तो आगे आने वाले महीनों में क्या होगा। हालांकि, आपको यहां बता दें कि मौसम विभाग का कहना है कि अभी आगे कुछ दिन भारी बारिश के आसार हैं, जिससे मौसम में ठंडक लौटेगी। भारत मौसम विज्ञाम विभाग ने आने वाले कुछ दिनों के लिए कई राज्यों में अलर्ट जारी किया है।

अलर्ट जारी करते हुए बिहार, ओडिशा, असम, मेघालय, अरुणाचल प्रदेश, उप हिमालय पश्चिम बंगाल और सिक्किम में भारी बारिश के साथ बर्फबारी का पूर्वानुमान लगाया गया है। वहीं, 28-29 फरवरी के आसपास जम्मू-कश्मीर, लद्दाख और हिमाचल प्रदेश में भी बर्फबारी और भारी बारिश का अनुमान लगाया गया है। इसके अलावा कोहरे और बिजली कड़कने के बारे में भी चेतावनी जारी की गई है। आइए जानते है, हर राज्य का हाल...

छत्तीसगढ़ में ऑरेंज अलर्ट

रातभर रायपुर सहित प्रदेश के विभिन्न हिस्सों में जमकर ओलावृष्टि और बारिश हुई। भोर में बारिश थमने के बाद सुबह 6 बजे से फिर हल्की बारिश हुई। अभी आसमान में बदल छाए हुए है। बारिश का सिस्टम पूरे दिनभर बने रहने की संभावना है।

मौसम विभाग के मुताबिक अभी चक्रवात साउथ छत्तीसगढ़ के ऊपर 900 मीटर बना हुआ है। दूसरा चक्रवात साउथ पश्चिम मध्यप्रदेश के ऊपर 1.5 किलोमीटर बना है। चौथा चक्रवाती घेरा पूर्वी उत्तर प्रदेश के ऊपर 0 प्वाइंट 9 किलोमीटर पर अभी मौजूद है। इसके साथ ही मध्य छत्तीसगढ़ में पूर्वी और साउथ सिस्टम के मिलन के कारण पूरे उत्तर और मध्य छत्तीसगढ़ में हल्की से मध्यम बारिश होने की संभावना है।

हालांकि, इनसे सब्जी की फसल को भी नुकसान हो रहा है। ओला और बारिश से गेंहू और सब्जी के फसलों को भारी नुकसान पहुंचा है। लिहाजा सब्जियों की कीमतों में भी उछाल आएगा।



बता दें कि छत्तीसगढ़ में ऑरेंज अलर्ट जारी करते हुए मौसम विभाग ने उत्तरी छत्तीसगढ़ अंबिकापुर, सरगुजा, बस्तर, कोंडागांव, जशपुर, बेमेतरा, कवर्धा और पेंड्रा में तेज बारिश की संभावना मौसम विभाग ने जताई है।

झारखंड में मौसम बदला

झारखंड में एक बार फिर मौसम बदल गया है। बारिश के बीच ठंड और कनकनी भी लौट आई है। पलामू में खूब ओले पड़े, यहां पहाड़ों पर बर्फबारी सा नजारा दिखा। जिला मुख्यालय मेदनीनगर समेत चैनपुर ,सतबरवा लेस्लीगंज ,पाटन आदि प्रखंडों में मंगलवार दिन के करीब 7:45 बजे अचानक छाए बादल से आधी रात का नजारा हो गया। इसके बाद जबरदस्त बारिश शुरू हो गई। साथ में ओलावृष्टि भी हुई। मौसम केंद्र, रांची के मुताबिक बुधवार को ऐसी ही स्थिति बनी रहेगी। इस दौरान 30 से 40 किलोमीटर प्रति घंटे की रफ्तार से हवा चलेगी और तेज बारिश होगी।

बिहार में बदला मौसम का मिजाज

बिहार में अगले 48 घंटे तक हल्की बारिश के आसार हैं। मंगलवार को भी सुबह में कई इलाकों में गरज के साथ बारिश हुई। इससे दलहनी फसलों को नुकसान होने की संभावना जताई गई। राजधानी पटना सहित जहानाबाद, वैशाली, गोपालगंज, बक्सर, सिवान, पश्चिमी चंपारण सहित कई जिलों में अहले सुबह से हो रही बारिश से तापमान में गिरावट आ गई है और लोगों को फिर से ठंड महसूस हो रही है।

उत्तराखंड में भी भारी बारिश और बर्फबारी

27 फरवरी को प्रदेशभर में भारी बारिश और बर्फबारी होने की संभावना है। पहाड़ों में बर्फ पिघलने और सर्द हवाएं चलने के कारण मैदानों में सुबह-शाम ठिठुरन बनी हुई है। वहीं, उत्तरकाशी में हल्की बारिश के चलते ठंड में इजाफा हो गया। मौसम विज्ञान केंद्र बिक्रम सिंह के अनुसार उत्तराखंड में अभी मौसम का मिजाज बदला-बदला ही रहेगा। पश्चिमी विक्षोभ के पश्चिमी उत्तर प्रदेश पहुंचने के कारण उत्तराखंड में बारिश के आसार बने हुए हैं, जबकि 27 फरवरी को पश्चिमी विक्षोभ के हिमालय से टकराने की संभावना है। इससे प्रदेश के कई इलाकों में बारिश और बर्फबारी हो सकती है।

Delhi-NCR में गर्मी

हाल ही में राजधानी दिल्ली का मौसम सुहाना हुआ था, लेकिन बारिश का असर खत्म होते ही दिल्ली-एनसीआर में तापमान फिर बढ़ने लगा है। मौसम विभाग ने बताया कि पश्चिमी विक्षोभ न होने से आने वाले दिनों में गर्मी बढ़ जाएगी।

मौसम विभाग के मुताबिक, इस सप्ताह अधिकतम 28, जबकि न्यूनतम तापमान 15 डिग्री सेल्सियस तक पहुंच सकता है। शनिवार को पश्चिमी विक्षोभ के सक्रिय होने पर बादल छाएंगे और हल्की बारिश होने की भी संभावना है।

ओडिशा में येलो अलर्ट जारी

ओडिशा के कई इलाकों में 25 फरवरी से आने वाले तीन दिन भारी हो सकते है। मौसम विभाग ने यहां भारी बारिश की चेतावनी जारी कर रखी है। कुछ जगहों पर हल्की से मध्यम बारिश होगी, तो कुछ जगहों पर गरज के साथ भारी बारिश की संभावना है। छह जिलों में येलो अलर्ट जारी किया गया है। मौसम विभाग ने कहा है कि ओडिशा के कई हिस्सों में आने वाले दिनों तक तीव्र वर्षा हो सकती है। भुवनेश्वर स्थित क्षेत्रीय मौसम विभाग के कार्यालय के अनुसार 25 से 27 फरवरी तक तटीय जिलों उत्तर तटीय तथा उत्तरी आंतरिक क्षेत्रों में कई इलाकों में हल्की से मध्यम बारिश होगी।
