This is due to a low-pressure region over the South-West Bay of Bengal off the coast of Sri Lanka, as well as the associated cyclonic circulation (extending up to 3.1 km above mean sea level), which is expected to travel westwards during the next 48 hours, according to IMD.
"Thunderstorm & lightning very likely over Kerala & Mahe, Tamilnadu, Puducherry & Karaikal and Coastal Andhra Pradesh during October 28 to November 1, and over Rayalaseema during October 29 to November 1, 2021," added IMD.
This is mainly due to dry weather which will prevail over most parts of Northwest, West & Central India and many parts of East & Northeast India during the next five days, as per the reports from IMD.
According to the Indian Meteorological Department (IMD) in Thiruvananthapuram, the southwest monsoon has left the entire country.
