New Delhi: The India Meteorological Department (IMD) has predicted heavy rainfall over West Bengal and Odisha as a melancholy which is transferring in the direction of which lies over the Bay of Bengal is more likely to transfer northeastwards and intensify right into a cyclonic storm by the night of May 25 and attain the West Bengal coasts as a extreme cyclonic storm by Sunday night.
Under the affect of the cyclonic storm, the coastal districts of West Bengal and adjoining districts of North Odisha are more likely to witness heavy to very heavy rainfall on May 26 and May 27.
The IMD has issued a warning for tough sea situations attributable to an approaching cyclonic storm. Weather is anticipated to worsen by the night of May 24. The meteorological division advises fishermen to keep away from venturing into the Bay of Bengal till the morning of May 27, 2024.
This is the primary cyclone within the Bay of Bengal this pre-monsoon season and shall be named Remal, in accordance with a system of naming cyclones within the Indian Ocean area.
“The system will concentrate into a depression over central Bay of Bengal by Friday morning. It will further intensify into a cyclonic storm on Saturday morning and reach Bangladesh and the adjoining West Bengal coast as a severe cyclonic storm by Sunday evening,” IMD scientist Monica Sharma instructed PTI.
According to the IMD, the cyclone might attain a wind velocity of 102 kilometres per hour on Sunday.
The Met workplace has warned of very heavy rainfall within the coastal districts of West Bengal, north Odisha, Mizoram, Tripura and south Manipur on May 26-27.

Fisherfolk out at sea have been suggested to return to the coast and never enterprise into the Bay of Bengal till May 27.
Scientists say cyclonic storms are intensifying quickly and retaining their efficiency for longer intervals attributable to hotter sea floor temperatures, a results of oceans absorbing a lot of the extra warmth from greenhouse gasoline emissions.
The previous 30 years have witnessed the very best sea floor temperatures since information started in 1880.
According to senior IMD scientist DS Pai, hotter sea floor temperatures imply extra moisture, which is beneficial for the intensification of cyclones.
Madhavan Rajeevan, former secretary of the Union Ministry of Earth Sciences, stated a sea floor temperature of 27 levels Celsius and above is required for a low-pressure system to accentuate right into a cyclone. The sea floor temperature within the Bay of Bengal is round 30 levels Celsius at current.
“The Bay of Bengal and the Arabian Sea are very warm at present, so a tropical cyclone can easily form,” Rajeevan stated.
But tropical cyclones should not solely managed by the ocean; the environment additionally performs an vital function, particularly by way of vertical wind shear — a change in wind velocity and/or wind route with altitude.
“A cyclone will not intensify if the vertical wind shear is very large. It will weaken,” Rajeevan stated.
Models counsel the cyclone is not going to have an effect on the monsoon progress, the senior meteorologist stated.
Pai, nevertheless, stated it might have an effect on the progress of the monsoon in some components.
He instructed PTI, “Initially, the system will help the monsoon progress over the Bay of Bengal. Thereafter, it will detach from the monsoon circulation and pull a lot of moisture, which could result in a slight delay in the monsoon progress in that area.”
