Mumbai: IMD warns of 'extremely heavy rainfall' in city on June 13 and 14

Following a respite from rains on Friday after continuous downpour over the last two days, the Indian Meteorological Department has issued an 'extremely heavy rainfall' warning in Mumbai and adjoining areas on June 13 and June 14. This has prompted Brihanmumbai Municipal Corporation to alert disaster management agencies.

IMD's bulletin on Friday evening stated that: "Mumbai and neighbouring areas are "very likely" to receive extremely heavy rainfall at isolated places on Sunday. It also issued a similar `red alert' for Ratnagiri and Raigad districts in coastal Maharashtra for June 13 and June 14. A few places in Mumbai and neighbouring Thane may receive heavy rains on Saturday too, it said.

Rainfall of more than 204.5 mm in 24 hours is considered extremely heavy.

"Since IMD has issued a 'heavy rain' warning for Mumbai on June 13 and June 14. Consequently, the fire department, and all disaster management units are have been asked to remain on alert. Adequate manpower is available at the main emergency control room and backup control room," said a senior BMC official.

Besides this the civic body said that BEST (Transport and Electricity) and Adani Energy have been put on high alert at all substations and their support teams are well equipped and vigilant, officials informed.

"Apart from alerting the disaster management agencies, the civic Education department has been asked to identify locations for emergency shelters. We have marked residential areas near the Mithi river and is ready for evacuation if the situation worsens. We have already started coordinating with NDRF, Coast Guard and Navy. They'll be available to help if needed," the official added.

"Mumbai, Thane, Raigad and Ratnagiri districts are very likely to receive extremely heavy rains at isolated places on Sunday. Raigad and Ratnagiri districts have a similar alert for Saturday as well. The satellite image has shown convective clouds over Mumbai and adjoining areas," said Jayanta Sarkar, deputy director-general of IMD Mumbai.

He added: "Mumbai and Thane districts would "very likely receive heavy to very heavy rainfall at a few places even on Saturday."

There would be moderate spells in the rest of Maharashtra with thunderstorms and lightning in the next two days with varied intensity, the forecast the IMD further said.

Mumbai completed its monthly rainfall target for June in 10 days

In the first 11 days of June, Mumbai's Santacruz observatory has recorded 534.3 mm of rainfall against the monthly normal rainfall of 505.0 mm for June. At Colaba, 247.0 mm of cumulative rainfall has been recorded during the same period as against the average monthly rainfall of 540.9 mm for the month. "Heavy to very heavy rains are likely between June 12 to June 15 and 3-digit rainfall or more on daily basis is quite likely over Mumbai and suburbs. Mumbai, a city with a track record of drowning rains stands a chance this month to overtake its all-time June record of 1106.7mm established in 2015. Also, 4 digit monthly rainfall of 1029.8mm was achieved in 2012. With the active meteorological conditions hinting at vigorous monsoon rains, these records could go for a toss very soon," predicted Skymet Weather, a private weather agency.
