Rainfall is expected to increase significantly over the southwestern parts of Sri
Lanka from 03 June, with wet and windy conditions likely to continue during the 
next few days. According to the latest weather forecast, showers or thundershowers
will occur at times in the Western, Sabaragamuwa and North-Western provinces, as
well as in the districts of Galle, Matara, Kandy and Nuwara Eliya.

Residents in these areas should be prepared for **heavy rainfall exceeding 100 mm**
at some locations. Such intense rainfall may lead to localized flooding, water accumulation
in low-lying areas and difficult travel conditions. People living in landslide-prone
areas are advised to remain alert and follow updates issued by relevant authorities.

In addition to the rain, **strong winds of 40–50 kmph** are expected at times across
the island. Temporary localized strong winds and lightning may accompany thundershowers,
creating hazardous conditions for outdoor activities. The public is urged to take
necessary precautions to minimize damage to property and ensure personal safety.

### Marine Weather Forecast

Weather conditions at sea are also expected to deteriorate. Showers or thundershowers
will occur at several places in the sea areas extending from Puttalam to Hambantota
via Colombo and Galle.

Southwesterly winds will prevail with speeds of 30–40 kmph, increasing up to 50–
60 kmph at times in sea areas from Mullaittivu to Pottuvil via Kankasanthurai, Mannar,
Puttalam, Colombo, Galle and Hambantota. Other sea areas may also experience wind
speeds reaching 50 kmph.

As a result, sea areas along these coastal regions will be rough at times, while
other surrounding waters will remain fairly rough. Wave heights are expected to 
increase to around 2.0–2.5 metres in sea areas extending from Kalpitiya to Pottuvil
via Colombo, Galle and Hambantota.

Naval and fishing communities are advised to exercise caution, as temporarily strong
gusty winds and very rough seas can develop during thundershowers.
