The Early Warning Centre of the Meteorological Department has warned that heavy showers, strong winds and rough seas can be expected over the next 24 hours.

It said due to low-level atmospheric disturbances in the Northern seas areas, intermittent showers or thundershowers could be expected in the deep and shallow seas extending from the coast of Mannar to Trincomalee via Kankasanthurai.

It said temporary strong gusty winds of up to 70-80 kmph could be expected during showers or thundershowers and warned naval and fishing communities to be particularly vigilant.
