The India Meteorological Department (IMD) has issued a yellow alert for the Mumbai Metropolitan Region (MMR), predicting light to moderate rainfall on Saturday, May 25. The weather department scaled down the forecast warning from orange alert to yellow alert. IMD forecast expecting light to moderate showers, thunderstorms and lightning with gusty winds at isolated placesin Mumbai, Thane and Palghar till Tuesday, May 27. Red alert for Raigad district in Maharashtra has also been changed to orange. Downgraded weather forecast follows intense pre-monsoon activity across the Konkan coast and indicates an early onset of the southwest monsoon for the city and suburbs.
Mumbai's official monsoon onset date is June 11. The weather warnings changed because the cyclonic system remains too far south to significantly affect the city's weather. Less rainfall was observed on Thursday (May 22), after which an orange alert was issued, as per the weather experts, reported The Times of India.
Meanwhile, low-pressure areas are forming over the east-central coast of the Arabian Sea off the south Konkan coast until Friday morning. The cyclonic circulation over the sea may intensify into a depression within 24 hours.
