Rain is unlikely in the city at least till Saptami with the monsoon trough starting to move away and conditions unfavourable for showers, said the weatherman on Monday. The rainy first half of the month — the cumulative rainfall has crossed the aggregate “normal” for entire October, based on data between 1971 and 2000 — has disrupted many a festive shopping trip and stoked fears of a wet Puja.
“The monsoon trough has withdrawn from the western part of Gangetic Bengal and is expected to withdraw from the state within the next 48 hours,” said G.C. Debnath, director, India Meteorological Department, Calcutta. Last week’s rainfall in the city was caused by low-pressure areas and depressions over the Bay, and not the monsoon trough. But such wind systems are unlikely to cause rain “at least till the first couple of days of Puja”, added Debnath.
Temperatures are expected to rise slightly over the next couple of days. “Night and early morning temperatures have begun to drop but we will have clear skies and fair weather for some time,” said a Met official.
