The Indian Meteorological Department has issued an orange alert for Kerala till October 26 as the state is set to receive heavy rainfall and gusty winds.
The weather system is being influenced by a low-pressure area lying over the the Southwest bay of Bengal and adjoining areas of Tamil Nadu. The associated cyclonic circulation extends up to mid-tropospheric levels.
The state can expect heavy to very heavy rainfall of 115.6-204.4 mm at isolated places for the next four days according to a bulletin by the IMD.
An orange alert for very heavy rain had been issued in all districts except Alappuzha, Ernakulam, Thrissur, Palakkad and Malappuram, which were issued an alert for heavy rain.
Residents have been advised to avoid flooded roads and waterlogged underpasses along with swollen streams.
The upper air cyclonic circulation, which was initially spotted near Thailand and Myanmar, has moved into the North Andaman Sea.
The system is expected to move west-northwestwards, potentially forming a low-pressure area over the south-east and adjoining east-central Bay of Bengal around 23 October.
A separate low-pressure area over the south-western Arabian Sea is also active with an associated cyclonic circulation extending up to 5.8km above sea level. The system is expected to move towards the Somali coast.
Fishermen have been advised not to venture into the sea off the Kerala coast due to the rough conditions and the continuous rain.
