The Meteorological Service of Jamaica has issued a flash flood watch for all parishes as a low-pressure system across the southwestern Caribbean produces showers and thunderstorms across the region.

The flash flood watch will remain in effect until 8:00 a.m. on Friday, November 17.

The Meteorological Service says the environment appears conducive for some additional development and there is now a 60 per cent chance of the formation of a tropical cyclone (tropical depression or tropical storm) over the next two days.

The system is currently moving northeastward across the region and the centre is expected to move near to or over Jamaica on Friday afternoon, before continuing northeastward and away from the island.

The local weather forecast is for cloudy conditions with widespread rainfall and occasional heavy thunderstorms to affect all parishes today, November 16, through to Saturday morning, November 18.

Strong gusty winds are also likely, especially across southern parishes.

Fishers and marine interests are urged to exercise caution as sea conditions are expected to deteriorate due to thunderstorms and gusty winds.

The Meteorological Service says it will continue to monitor the system.
