West Bengal rain is expected to continue across several districts after the remnants of Cyclone Arnab developed into a well-marked low-pressure area, while another system over the Bay of Bengal is raising the possibility of further showers. Kolkata and most of south Bengal received light to moderate rain on Friday, while parts of north Bengal were placed under heavy-rain alerts, according to a report by Sangbad Pratidin.
The report said the combined influence of the two systems brought overcast conditions to Kolkata and neighbouring districts from Friday morning. The weather system formed after the remnants of Cyclone Arnab weakened into a distinct low-pressure area. A separate low-pressure area was also expected to develop over the adjoining Bay of Bengal from a circulation over the Andaman Sea.
The second system was located over the south-east Bay of Bengal and adjoining areas of the Andaman and Nicobar Islands and the Andaman Sea, the report said. It is forecast to move gradually north-westwards and strengthen into a depression. The India Meteorological Department has initially indicated a possible movement towards the Andhra Pradesh coast.
Its influence is expected to bring light to moderate rain accompanied by thunderstorms across several districts. Sangbad Pratidin reported that weather conditions would remain broadly similar until 5 November, with dry conditions in some areas occurring alongside intermittent rain. The forecast adds uncertainty for daily travel and outdoor activity because rainfall may remain uneven across districts rather than affecting the state uniformly.
North Bengal is expected to see a rise in the spread and intensity of rainfall from Friday. The report said rain was possible in all districts of the region. Darjeeling and Jalpaiguri were placed under an orange alert for very heavy rain, with isolated locations potentially receiving up to 200 millimetres. Kalimpong and Alipurduar were placed under a yellow alert for heavy rain.
The northern districts may also experience gusty winds reaching 30 to 40 kilometres per hour. Such conditions can affect road travel, exposed construction activity and local electricity infrastructure, although the report did not cite any specific disruption or damage. For cities and towns, the continuing rainfall makes drainage capacity, traffic management and the safety of pedestrians and road users immediate operational concerns.
The report said rainfall would ease somewhat from the following day, with partly cloudy skies expected between 1 and 5 November. However, scattered showers may continue while the two weather systems remain active. Authorities and residents will therefore need to follow updated forecasts and district-level alerts, particularly in Darjeeling, Jalpaiguri, Kalimpong and Alipurduar, where the reported warnings indicate the highest rainfall risk.
