Under the influence of the system, rough seas and strong winds (50-60 kmph), gusting up to 70-80 kmph can be expected over the southeast Arabian sea area (00-15N, 60E75E) during next few days.
Heavy showers or thundershowers and rough seas associated with sudden increase of wind speed up to 55-60 kmph are likely in deep and shallow see areas extending from Kankesanturai to Hambantota via Mannar, Colombo and Galle during next 24 hours.
Accordingly, naval and fishing communities are advised not to venture into the southeast Arabian sea area (00-15N, 60E-75E) from May 14, until further notice.
Those who are in aforementioned sea regions (00-15N, 60E-75E) are advised to return to coasts or moved safer areas as soon as possible.
