May 24, Colombo (LNW): South-West monsoon is gradually getting established over the island, and showers or thundershowers, therefore, will occur at times in Western, Sabaragamuwa and North-western provinces and in Galle, Matara, Kandy and Nuwara-Eliya districts, the Department of Meteorology said today (24).
Fairly heavy falls above 50 mm are likely at some places in Western and Sabaragamuwa provinces and in Galle and Matara districts.
Mainly fair weather will prevail over the rest of the island.
Fairly strong winds about (30-40) kmph can be expected at times over Western slopes of the central hills, Northern, North-central, North-western and Southern provinces and in Trincomalee district.
The general public is kindly requested to take adequate precautions to minimise damage caused by temporary localised strong winds and lightning during thundershowers.
