Weather System & Forecast

♦ Yesterday’s ‘Western Disturbance’ as a cyclonic circulation over  north Pakistan & neighbourhood  now lies over Punjab & neighbourhood extending upto upper tropospheric levels.  The induced cyclonic circulation now lies over northeast Rajasthan & neighbourhood in lower levels. Though the moisture feed from the Arabian Sea has been cut off with the eastward movement of the system, low level southeasterly winds from the Bay of Bengal are feeding moisture towards eastern India,  where the upper  level features are also conducive for development  of  thunderstorms  and hailstorms.  However,  this  feature is very likely to shift further eastwards by tomorrow leading to a drastic reduction  in  the  thunderstorm  activity  over Bihar, Jharkhand,  north Chhattisgarh and West Bengal  from 15th March and  increase over the northeastern states. Significant weather expected is as follows:

• Light to moderate scattered to fairly widespread rainfall/snowfall is very  likely  over Jammu, Kashmir, Ladakh & Gilgit and Baltistan, Himachal Pradesh, Uttarakhand with hailstorm over Uttarakhand and thunderstorm over Himachal Pradesh during next 24 hours.
• Light to moderate fairly  widespread  rainfall very likely  over  Punjab   and   East  Uttar  Pradesh  and scattered rainfall over Haryana, Chandigarh, Delhi and West Uttar  Pradesh during  next  24  hours and decrease thereafter. Hailstorm with gusty winds is also likely over the same region during next 24 hours.
• Moderate scattered to fairly widespread  rainfall   with  isolated thunderstorm/hailstorm, lightning/gusty wind winds (speed reaching 40-50 kmph  occasionally) over  north  Chhattisgarh,  Bihar, Jharkhand and West Bengal & Sikkim during  next  24  hours. Isolated heavy falls are also likely over Jharkhand and Bihar during the same period.
