Kolkata, Bengal Rain From 9 November; Andaman Heavy Rain Alert: IMD

Kolkata and the rest of Gangetic West Bengal are likely to get isolated to scattered rain from Monday, 9 November, through 12 November, the India Meteorological Department (IMD) said in its press release of 6 November. The Andaman and Nicobar Islands face the heaviest weather: widespread rain from 8 to 12 November, with isolated heavy rain on 9, 10 and 11 November. IMD links the spell to an upper-air cyclonic circulation over east Bangladesh.

Wet Days Ahead for Bengal and Jharkhand

Isolated to scattered rain is forecast over Jharkhand and Sub-Himalayan West Bengal and Sikkim from 9 to 11 November, and over Bihar on 10 November. Odisha gets a second round on 10 and 11 November, after showers on 6 and 7 November. Thunderstorms with lightning are likely at isolated places in Gangetic West Bengal and in Sub-Himalayan Bengal and Sikkim on 10 November.

The bulletin does not carry an orange or red warning for these regions. Commuters in Kolkata should still plan for waterlogging on low-lying roads during heavier showers, and farmers with harvested paddy in the open should keep it covered, in line with the standard agromet advice IMD issues with these forecasts.

Heavy Showers and Lightning in the Andamans

For the Andaman and Nicobar Islands, IMD expects isolated thunderstorms with lightning from 9 to 12 November on top of the heavy rain. The department’s general advisory for such spells asks people to avoid sheltering under trees during lightning, unplug electrical appliances, and regulate tourism and marine activity. IMD’s 5 November bulletin had issued no fishermen warning for any day up to 11 November.

Nights have been cool across the east. The same bulletin recorded minimum temperatures below normal by 1.6 to 3 degrees Celsius at a few places in Gangetic West Bengal and Odisha on 5 November.

Fresh Western Disturbance From 10 November

IMD says a fresh Western Disturbance will affect northwest India from 10 November, which is why rain and snow are forecast for the Himalayan states later in the week; see IPB’s report on the Jammu and Kashmir and Himachal forecast and the Northeast heavy rain alert. Earlier eastern updates are in IPB’s report on Bihar, Sikkim and Bengal, and all forecasts sit on the Weather Updates page. IMD will issue its next bulletin within a day.
