This is the weather update posted by @rameshtahlan sir for 2nd March. If this keeps up, you will likely encounter heavy snow in Kinnaur. Keep a backup plan ready, just in case and you should be fine. There is no issue in traveling to Himachal, unless war breaks out.
Manali – Leh Highway snow clearance operation is set to begin in a week, if the weather remains favorable. Initially effort would be to clear Gulaba – Rohtang route and restore connectivity within Lahaul Valley.
Road clearance work halted due to heavy snowfall and rain in Himachal Pradesh. Higher reaches in Lahaul & Spiti, Kinnaur, Chamba and Kullu received fresh snowfall, while Mandi, Bilaspur, Hamirpur, Kangra and Solan had widespread rains causing sharp fall in temperature.
Kalpa had 5 cm of snowfall, while Manali received 3cm.
Rohtang Pass and Kothi received 30 cm of snowfall.
