West Bengal weather conditions are expected to remain unsettled as two low-pressure systems influence the region, bringing rain to Kolkata and several districts while raising the risk of very heavy rainfall in parts of North Bengal. The weather system is also expected to produce thunderstorms and gusty winds in some areas.
The remnants of Cyclone Arnab have weakened into a well-marked low-pressure area, while another low-pressure system is developing over the southeast Bay of Bengal and adjoining areas of the Andaman and Nicobar Islands and the Andaman Sea. According to the forecast cited by Sangbad Pratidin, the second system is likely to move northwestwards and strengthen into a deep depression.
The India Meteorological Department has initially forecast the system’s movement towards the Andhra Pradesh coast. Its influence is expected to bring light to moderate rain with thunderstorms across several districts of West Bengal. The report said that the overall weather pattern is likely to remain similar until November 5, with dry conditions in some areas alongside intermittent rain.
Kolkata and most districts of South Bengal received light to moderate rain from Friday morning, with cloudy skies reported across the region. The expected rain could affect road conditions, local travel and outdoor activity, although the supplied forecast does not provide a district-wise rainfall total for South Bengal.
The more significant alert is for North Bengal, where rainfall is expected to increase from Friday. Rain is likely across all districts in the region. Darjeeling and Jalpaiguri have been placed under an orange alert for very heavy rain, with isolated locations potentially receiving up to 200 millimetres. Kalimpong and Alipurduar are under a yellow alert for heavy rain.
The forecast also warns of gusty winds reaching 30 to 40 kilometres per hour in the affected areas. Such conditions can create difficulties for road users and disrupt outdoor movement, particularly in locations experiencing intense rain or thunderstorms. The report did not provide details of any confirmed damage, flooding or transport disruption at the time of publication.
From November 1 to November 5, skies are expected to remain partly cloudy overall. Rainfall intensity is forecast to decrease somewhat from the following day, although scattered showers are expected to continue. The immediate focus for authorities and residents remains the North Bengal districts under orange and yellow alerts, while Kolkata and South Bengal continue to face intermittent rain under the influence of the wider weather systems.
