A low-pressure area brewing over the Bay of Bengal is likely to bring heavy rainfall across Gangetic West Bengal during the weekend, the India Meteorological Department (IMD) said in a Thursday bulletin. The weather forecasting agency said that the low-pressure area will likely become a well-marked low-pressure area under the influence of a cyclonic circulation lying over Myanmar and the Bay of Bengal in the subsequent 48 hours, bringing a fresh spell of heavy rainfall over East India.

The IMD also noted that the conditions are becoming favourable for further withdrawal of Southwest Monsoon from some more parts of Northwest and adjoining Westcentral India during the next two to three days.

Under the influence of these weather systems, the Andaman & Nicobar Islands are expected to witness widespread rainfall, thunderstorms, and lightning during this period, with the possibility of isolated heavy rainfall from September 28-30. Squally weather with wind speeds reaching 45-55 km/h, gusting to 65 km/h, is anticipated from September 28 to October 1.

In South India, the ghat areas of Tamil Nadu are likely to experience light to moderate fairly widespread to widespread rainfall with isolated heavy rainfall from September 28 to 29, while Coastal Karnataka is expected to see similar weather conditions from September 28 to October 1.
