The Flash Flood Watch remains in effect for sections of northern and southeastern parishes.

The Met Service said the advisory is for low-lying and flood-prone areas of Trelawny, St. Ann, St. Mary, Portland, St. Thomas, Kingston and St. Andrew.

The watch will remain in effective until 5:00 p.m. on Friday.

Meantime, the watch for Westmoreland, Hanover and St. James, has been discontinued.

A broad trough across the central Caribbean continues to influence weather conditions across Jamaica, with the most intense activity associated with this system expected to affect sections of northern and south-eastern parishes, until Friday.

Observations indicate that light to moderate and occasionally heavy showers and thunderstorms have been affecting most parishes throughout Thursday.

The forecast is for cloudy conditions, with widespread showers and occasional heavy thunderstorms to continue affecting all parishes through to late Friday.

Improved weather conditions are expected late Friday into Saturday, as the trough weakens across the central Caribbean.

Fishers and other marine interests should exercise caution as sea conditions will deteriorate due to thunderstorms and strong gusty winds.

A Flash Flood Watch means that flash flooding is possible, and residents are advised to take precautionary measures, keep informed by listening to further releases from the Met Service and be ready for quick action if flooding is observed or if a warning is issued.
