The weather bureau has issued a red alert for Sunday, predicting isolated extremely heavy rain spells in Mumbai, Thane, Palghar and Raigad. "Monsoon current over North Konkan is vigorous, allowing short bursts of intense rain in Mumbai and sustained rainfall activity over surroundingareas," said Bishwambhar Singh, director, regional meteorological centre, IMD Mumbai ."These weather systems are allowing more moisture incursions over the coast and strong westerly winds leading to heavy to very heavy rain, with isolated extremely heavy spells expected on Sunday." However, private weather forecasting agencies and independent meteorologists had a contrary view. "While heavy to very heavy rain is likely between Saturday night and Sunday morning, the intensity is likely to be lesser than what was witnessed over the past 24 hours, as rain-bearing factors are weakening. However, with the low pressure strengthening over the east coast, rain intensity is likely to increase again from Monday," said Ma hes hP ala wat, vice- president( meteorology and climate change), Skymet. Sridhar Balasubramanian, associate professor, department of mechanical engineering and associate faculty, IDP Climate Studies, Indian Institute of Technology- Bombay, said,"Mumbai and surrounding areas can expect heavy to very heavy rains with a maximum of 150mm up to Sundayafternoon, but not more."
