Mumbai’s wait for southwest monsoon is here to stay with the India Meteorological Department (IMD) on Wednesday announcing that rainfall activity across Maharashtra is likely to remain isolated for a few days with the advancement of monsoon forecast after June 24.

The weather bureau has extended its yellow alert of hot and humid conditions in Mumbai until Friday, with temperatures likely to soar across the city.

The usual date of monsoon onset in Maharashtra is June 11. However, after an advancement from Kerala to South Maharashtra by June 8, the surge weakened, delaying its onset.

On Wednesday, the IMD stated that monsoon is likely to remain stalled until at least June 24, following which forecasting models have indicated an uptick in rain activity over Konkan. “Rainfall activity over most parts of Maharashtra is likely to remain isolated during the next 4-5 days,” said the IMD in a statement, adding that the bureau is continuously monitoring the synoptic conditions.

Meteorologists from the IMD have attributed the delayed advancement of monsoons to a lack of strong surge, weakened monsoon circulation, absent systems such as cyclonic circulations and offshore troughs as well as lack of prevailing large-scale circulation patterns like Madden-Julian Oscillation (MJO).

Amid sparse pre-monsoon spells and delayed onset of monsoon, the IMD has forecast hot and humid conditions across Mumbai and neighbouring districts of Thane, Palghar and Raigad where a yellow alert is likely to stay until June 19. As per the forecast bulletin, temperatures are likely to surpass 35 degrees in Mumbai while in Thane temperatures may escalate over 36 degrees.

On Wednesday, day temperatures soared to 35.8 degrees — over four degrees above normal — in Colaba station while in the Santacruz observatory, maximum temperatures touched 34.8 degrees Celsius. The above normal temperatures came after pockets of the city experienced light drizzle in the early hours with the island city and western suburbs receiving 0.04 mm and 0.01 mm of rain each.
