Monsoon alert: Mumbaikars warned of ‘extremely heavy rains’ by IMD

New Delhi: The India Meteorological Department (IMD) has forecast ‘extremely heavy rain’ over this weekend in Mumbai advising people to stay indoors.

The forecast states a possibility of up to 200mm or more rain during a 24-hour period. As per the weather department, 15.6mm to 64.4mm of rain is considered ‘moderate’; 64.5mm to 115.5mm is ‘heavy’; 115.6mm to 204.4mm is ‘very heavy’ and more than 204.5mm is ‘extreme’, reported HT.

A warning was issued on Thursday stating the likelihood of “extremely heavy rainfall at isolated places” from Friday.

The weather advisory further read, “As rainfall activity is likely to enhance from June 9, people are advised to abstain from outdoor activities as much as possible during the period and also watch for weather updates from Regional Meteorological Centre, Mumbai.”

In July 2005, large parts of the city were flooded and many people lost their lives when Mumbai recorded 900 mm of rainfall in 24 hours.

While the city recorded no rainfall on Tuesday and Wednesday, gusty winds lashed the city Thursday morning, highetening the moisture level.

The weather bureau said these were still pre-monsoon showers but conditions were favourable for the southwest monsoon to set in over Maharashtra by Friday and over Mumbai by Saturday.

The southwest monsoon arrived in Goa on Thursday, the normal onset date for the southwest monsoon over Mumbai is June 10, but pre-monsoon showers have already caused concerns warning the citizens of flood.
