In contrast, North Bengal’s Darjeeling, Kalimpong, Jalpaiguri, Alipurduar and Cooch Behar will experience thunderstorms with lightning and moderate rain on Wednesday and Thursday. Scattered showers may continue in these districts, with Darjeeling and Kalimpong at higher risk of intense storms. By Friday, North Bengal’s lower districts, like Malda, may turn dry with temperatures rising 3-5°C by Sunday.
The IMD also announced an early onset of the southwest monsoon in Andaman-Nicobar, expected on May 13th nine days ahead of the usual May 22nd date. This follows last year’s early arrival on May 19th, signalling a potentially active monsoon season. The early monsoon is driven by favourable conditions in the Bay of Bengal, with low-pressure systems likely to bring heavy rain to Andaman’s islands.
