become a severe Cyclonic Storm

May 10, 2023

The Met. Department has issued a warning on the Deep Depression over South-East Bay of Bengal.

According to the Red Warning issued by the Natural Hazards Early Warning Centre of the Met. Department, the depression over the Southwest Bay of Bengal has intensified into a Deep Depression and lay centered near 8.8°N and 88.9°E at 08.30 a.m. of today (10th  May). It will intensify gradually into a cyclonic storm over the same region around today evening.

It will gradually intensify further into a severe cyclonic storm by 11th morning and very severe cyclonic storm by 11th mid-night over Southeast and adjoining Central Bay of Bengal. It is likely to move North-Northeastwards towards Bangladesh-Myanmar coasts on 14th May, 2023.

Due to this system, wind speeds will be (50-60) kmph and can increase up to 70-80 kmph in sea areas bounded by (03N - 20N) and (85E – 100E) during the next 24 hours. Heavy showers or thundershowers and very rough seas can also be expected in above sea areas.

Weather forecasts predict showers or thundershowers at times in the Western, Sabaragamuwa, Central, North-Western and Southern provinces. Fairly heavy showers about 75 mm are likely at some places in the Western, Sabaragamuwa and North-Western provinces and in Kandy, Nuwara-Eliya, Galle and Matara districts.

Several spells of showers will occur in the Northern province. Showers or thundershowers will occur at several places elsewhere over the island particularly during the afternoon or night.

Strong winds of about (40-45) kmph can be expected at times over western and southern coastal areas and along the western slopes of the central hills.

Naval and multi-day fishing communities are advised not to venture into the sea until further notice and are also requested to be attentive to forecasts issued in this regard.
