A low-level atmospheric disturbance currently prevailing over the southeastern Bay
of Bengal is likely to develop into a low-pressure area by tomorrow (13 March). 
Under the influence of this system, rainfall is expected to increase across Sri 
Lanka and the surrounding deep and shallow sea areas from tomorrow and over the 
next few days.The public, including fishing and naval communities, is urged to closely
monitor future forecasts and advisories.

Widespread showers or thundershowers are expected across most parts of Sri Lanka
tomorrow (13 March). Heavy rainfall of around 100–150 mm is possible at some locations
in the Central, Sabaragamuwa, Uva and Southern provinces. Other parts of the island
may experience fairly heavy rainfall exceeding 75 mm.

People living in mountainous areas are advised to remain alert to the possibility
of landslides, while residents in areas prone to flooding should be cautious of 
sudden flash floods caused by heavy rainfall. The public is also urged to take necessary
precautions to minimize accidents and damage caused by temporary strong winds and
lightning associated with thundershowers.

Satellite imagery captured at approximately 4.00 p.m. today (12 March) shows the
development of cumulonimbus clouds around Sri Lanka and the Bay of Bengal, indicating
active cloud development in the region.
