The India Meteorological Department (IMD) has forecasted heavy rainfall over several parts of Telangana from October 27 to 29, as the current depression over the Bay of Bengal is expected to intensify into a cyclonic storm.

Speaking to The Hindu, Dharma Raju, a scientist at the IMD Hyderabad centre, said that the weather system, currently in a depression stage, is likely to strengthen into a deep depression by October 26 before taking the shape of a cyclone on October 27. "We are anticipating heavy rains for Telangana on October 27 and 28," he said.

He added that the southern and eastern districts of the State are expected to receive the most impact, while Hyderabad may experience only light to intermittent rain. "For Hyderabad, it will be mostly light rain and skies will remain cloudy most of the time," he added.

For the next two days (October 25 and 26), the State will see only light to moderate rainfall, mainly in the eastern and southern parts. The situation is likely to change from the evening of October 27, once the depression transforms into a cyclone.

"From the evening of October 27 onwards, the weather scenario over Telangana completely changes. The system is most likely to cross on October 28, and that will bring heavy rains," Mr. Raju said.

The IMD scientist also said that the rainfall activity could continue till October 29, though its intensity will gradually decrease.

According to the IMD, a cyclonic circulation over the southeast Bay of Bengal and the adjoining South Andaman Sea is currently active. This system has led to the formation of a low-pressure area in the same region on the morning of October 24.

It is expected to move in a west-northwest direction and gradually intensify, first into a depression by October 25, then into a deep depression by October 26, and finally into a cyclonic storm over the southwest and adjoining west-central Bay of Bengal by the morning of October 27.
