**Showers and Rough Seas Expected Around Sri Lanka Over the Next 24 Hours**

**December 12, 2025** — The Department of Meteorology has issued a marine weather
forecast warning of showers, strong winds, and rough seas around the island during
the next 24 hours.

According to the advisory released at 5.30 a.m., **showers are likely in several
sea areas from Puttalam to Pottuvil**, covering regions off Mannar, Kankasanthurai,
and Trincomalee. Other sea areas may also experience **isolated showers or thundershowers**,
particularly during the evening or night.

**North-easterly winds** will prevail, with speeds ranging from **30–40 km/h**, 
the forecast states. Wind speeds could increase to **50–55 km/h** at times in the
stretch of sea from Colombo to Mullaittivu via Puttalam and Kankasanthurai, posing
risks to fishermen and maritime activities.

The sea condition between **Colombo and Mullaittivu** is expected to be **rough 
at times**, while the rest of the island’s surrounding waters will remain **moderate**.
Authorities caution that **temporarily strong gusts and very rough seas** may develop
during thundershowers, urging the naval and fishing communities to exercise caution.
