Heavy rainfall above 100 mm are likely at some places in these areas, the Department said. 

Showers or thunder showers will occur after 1.00 p.m. elsewhere of the island and Fairly heavy falls above 75 mm are likely at some places in these areas. 

Another low-pressure area is likely to form over Southeast and adjoining East-central Bay of Bengal around tomorrow and is likely to move west-northwestwards and intensify further, it said.
