The Department of Meteorology says the prevailing showery weather over the island is expected to continue today as well.
The Met Department said showers or thundershowers will occur at times over most parts of the island.
Very heavy showers above 150mm are likely at some places in the Northern, North-western, Western and Sabaragamuwa provinces and in the Anuradhapura, Trincomalee, Nuwara-Eliya and Kandy districts.
Meanwhile, heavy showers of about 100 mm can be expected at some places in the Matale, Polonnaruwa, Galle and Matara districts.
The general public has also been requested to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
