Mumbai: After the onset of southwest monsoon, the India Meteorological Department has issued a yellow alert for Mumbai with warning of thunderstorms, lightning and light to moderate rain for next 48 hours.

Meanwhile, fishermen are advised not to venture along and off North and South Maharashtra till June 13.

Fishermen are advised not to venture along and off North Maharashtra coast during the above-mentioned period."

The weather forecaster said that thunderstorms accompanied by lightning and heavy rain, with gusty winds reaching speeds of 62-87 km/h, are very likely to occur in isolated areas within the districts of Mumbai, Thane, and Raigad. According to the IMD, the city is expected to experience a generally cloudy sky with heavy rainfall over the next few days.

Earlier on Sunday, Mumbai saw rainfall, indicating the start of the anticipated weather activity. The IMD had earlier reported that the southwest monsoon has advanced to parts of the central Arabian Sea, south Maharashtra, Telangana, south Chhattisgarh, south Odisha, and more areas of coastal Andhra Pradesh.
