♦ An active Western Disturbance approached Northwest India from 22^nd October 2021 and was seen as a cyclonic circulation in the lower tropospheric levels along with a trough aloft in the middle tropospheric levels; before moving away east-northeastwards on 26^th October 2021, this system and its induced cyclonic circulation supported by moisture incursion from Arabian Sea have caused fairly widespread to widespread rainfall activity over Western Himalayan Region on two to three days and scattered to fairly widespread rainfall/thunderstorm activity over adjoining plains of Northwest India on one or two days along with isolated heavy rainfall activity over some parts during the week; isolated very heavy rainfall also had occurred over Jammu Kashmir & Ladakh on one day along with; Severe thunderstorm activity along with hailstorms also had been reported over these region during the passage of the system.

Heavy rain:

Temperature Scenario:

♦The highest maximum temperature of 36.7^oC had been recorded at Ratnagiri (Konkan & Goa) on 23^rd October 2021 and the lowest minimum temperature of 11.0^oC had been recorded at Sikar (East Rajasthan) on 27^th October 2021 over the plains of the country during the week.
