According to the India Meteorological Department (IMD), the city is in for the resurgence of monsoon in the coming days amid a yellow alert sounded in the city until Tuesday morning.
Mumbai largely receives its annual quota of rain during the four monsoon months spanning June to September. During the course of the monsoon, the city’s Santacruz station in the suburbs receives an average of 2319 mm rain while the Colaba coastal observatory registers 2095 mm rain.
Data furnished by the IMD shows that even with three months of monsoon to go, the Colaba station has already received 1187 mm rain since May, accounting for 57 percent of its annual quantum of rain which stands at 2095 mm. Meanwhile, having received 1028 mm rain so far, the Santacruz station has clocked in 44 percent of its annual average rain for the year.
The significant quantum of rain has been spurred by heavy pre-monsoon showers throughout May, followed by a historic early onset of southwest monsoon in Mumbai, this year, when the monsoon arrived into the bay on May 25. Owing to the early onset, the total stock in the seven lakes catering to Mumbai’s potable water supply soared to nearly 60 percent by Sunday morning–its highest for this day in at least past two years.
Despite the high quantum of rain received since May, IMD records show that the city’s monsoon quota (between June and July 6) has remained below normal with the IMD’s Santacruz station reeling under a deficit of 13 percent between June and July 6. Meteorologists attributed the current deficits to the relative dry spell in June owing to the absence of active weather systems, which lead to convection and usher in monsoon currents.
However, the IMD has indicated that Mumbai is slated to experience a resurgence in showers in the coming days. While Mumbai and Thane districts have been placed under a yellow alert owing to the likelihood of heavy rainfall accompanied by stormy surface winds until Tuesday morning, the neighbouring districts have been placed under an orange alert until at least July 9. For the record, July is Mumbai’s wettest month of the year during which the Santacruz station receives an average of 855 mm rain.
