The Jamaica Meteorological Service says a broad trough across the western Caribbean will begin impacting the island by as early as mid-afternoon, bringing increased chances of heavy rainfall on Thursday (May 12).

The Met Service, in a late Wednesday bulletin, advised that most parishes will be affected by the weather disturbance, which it expects to continue well into next week.

“The forecast is for cloudy conditions with periods of showers and thunderstorms, which could be heavy at times, to affect sections of most parishes beginning Thursday and continuing into early next week. Additionally, strong winds are expected to affect mainly southern and northeastern parishes beginning Thursday afternoon,” the local weather watchdog indicated.

What’s more, the Met Service urged fisherfolk and other marine interests to exercise caution out at sea—particularly for offshore areas of the south coast—as maritime conditions may quickly deteriorate in the vicinity of showers, thunderstorms, and strong winds.

With just two weeks left before the start of the 2022 Atlantic Hurricane Season, satellite imagery over the Caribbean notes the presence of a massive stationary front, which straddles much of Hispaniola, Puerto Rico, Turks and Caicos Islands and the southeastern islands of The Bahamas.

The maximum temperature expected in major cities Kingston and Montego Bay is 31 degrees Celcius respectively.

Additionally, the Met Service’s small craft warning remains in effect for offshore areas of the south coast due to strong winds and rough seas in the vicinity of thundershowers.
