The Met Department says that the Inter Tropical Convergence is affecting the weather over the country and that due to the active cloudiness associated with the ITCZ, sudden increase of wind speed (70-80 kmph for next 24 hours) is possible around the island.
Thundershowers will develop over most parts of the island and around the sea areas while heavy rain falls (more than 100mm) are also likely at some places, according to a severe weather advisory issued by the Early Warning Centre.
The possibility of sudden roughness of the sea areas around the island is high due to active cloudiness, it said.
Showers will occur at times in the sea areas off the coast extending from Trincomalee to Hambantota via Pottuvil and in the deep sea areas off the western coast. Showers or thundershowers will occur at several places over the other sea areas around the island.
