**Rough and Very Rough Seas Expected**

Marine conditions are expected to become particularly challenging over several coastal
areas during the next 24 hours. Showers or thundershowers will occur at several 
places in the sea areas extending from Chilaw to Hambantota via Colombo and Galle.

Winds over the surrounding seas will be westerly to south-westerly at speeds of 
30–40 kmph. Wind speeds may exceed 60 kmph at times in the sea areas extending from
Matara to Pottuvil via Hambantota. Winds may also increase up to 50 kmph in the 
sea areas from Batticaloa to Chilaw via Trincomalee, Kankasanthurai and Mannar, 
and from Galle to Matara.

The sea areas from Matara to Pottuvil via Hambantota are expected to be rough or
very rough at times. Naval and fishing communities are advised not to venture into
these waters until further notice. Other areas, including the seas from Batticaloa
to Chilaw and from Galle to Matara, may also experience rough conditions, requiring
fishing and naval communities to remain vigilant.

Wave heights may increase to around 2.5–3.0 metres in the sea areas extending from
Puttalam to Pottuvil via Colombo, Galle and Hambantota. Temporary strong gusty winds
and very rough seas may occur during thundershowers.

The public and marine communities are urged to closely monitor official weather 
updates and take necessary safety precautions as conditions may change rapidly.
