A depression over southern Arabian Sea is likely to intensify into a low pressure and bring heavy rainfall at isolated places in Kerala and southern Tamil Nadu during the next two days, the meteorological department said today.
In Kerala, Thiruvananthapuram city and Thrithala village in Palakkad district recorded 10 cm and 7 cm of rainfall respectively in the past 24 hours ending at 8.30 am today.
Thunderstorm and gusty winds are likely to occur in parts of interior Tamil Nadu, Kerala and Karnataka, he said.
Parts of Kerala have already begun receiving pre-monsoon showers. The southwest monsoon, which accounts for nearly 72 per cent of India's annual rainfall, normally sets over Kerala around June 1.
