Bay low-pressure to deepen, heavy rain alert in South Bengal
Over the Bay of Bengal, a big swirl of wind and clouds is getting stronger.
Weather scientists call it a low-pressure area, and they think it will become a deep depression.
A deep depression brings lots of rain and strong winds.
Some places in South Bengal, a part of India, will get heavy rain for the next few days.
The weather office put out a yellow alert, which is a warning that rough weather is coming.
Fishermen were told not to go out to sea until August 15 because the water will be dangerous.
Winds could blow as fast as 50 to 70 kilometers an hour.
There may also be thunderstorms with gusts of 30 to 40 kilometers per hour.
The rain should ease by Saturday and Sunday, with only light showers.
People are asked to stay alert and keep an eye on weather updates.
A low-pressure area over the Bay of Bengal is expected to intensify into a deep depression, bringing heavy rainfall across several districts of South Bengal.
The India Meteorological Department (IMD) issued a yellow alert for heavy rainfall in South 24 Parganas and Purba Medinipur districts.
Fishermen have been advised not to venture into the sea until August 15 due to rough sea conditions.
Wind speeds are expected to range between 50 kmph and 70 kmph, with thunderstorms and gusty winds of 30-40 kmph likely in most districts of South Bengal.
In North Bengal, Malda, Dakshin Dinajpur and Uttar Dinajpur are under a yellow alert for light to moderate rain, with isolated heavy showers possible in parts of Jalpaiguri and Alipurduar.
