Windward Islands brace for unusually early tropical storm conditions through Tuesday

An unusually strong system for June will pass through the southern part of the Windward Islands with tropical storm conditions on Monday night and Tuesday.

"The system is dubbed Potential Tropical Cyclone Two and could gather the name Tropical Storm Bret at any time on Monday and Monday night," according to AccuWeather Hurricane Expert Dan Kottlowski.

Potential Tropical Cyclone Two will cause winds and seas to build around the islands and the Venezuela coast through Tuesday.

Bathers and boaters should heed all advisories as seas and surf will become dangerous.

Because of the compact nature of the storm, adverse conditions are likely to hug the coast of Guyana and Venezuela, the southern part of the Windward Islands and a portion of the Leeward Antilles.

People on the islands from Trinidad and Tobago to Grenada, Margarita and Tortuga can expect showers and gusty thunderstorms to ramp up Monday night and Tuesday.

Rain is generally needed on these islands since they receive little rain on an annual basis. However, too much rain can fall too fast and lead to dangerous flash flooding and mudslides. Rainfall will average 2-4 inches with locally higher amounts possible.

It is possible the proximity to Venezuela will prevent the system from developing entirely. The center of the system may pass over part of northern Venezuela.

"Interaction with the large land mass of South America will cap the development of the tropical system to a tropical storm through Tuesday," Kottlowski said.

"As the system moves west-northwestward over the Caribbean Sea, it is likely to weaken, due to strong winds at mid-levels of the atmosphere on Wednesday," Kottlowski said.

Regeneration of the system is not likely beyond Wednesday.

It is possible that spotty showers and thunderstorms survive and expand northwestward across the Caribbean as the week progresses.

Conditions will improve from east to west across the Windward Islands and the Venezuela coast on Wednesday.

Tropical development in this part of the Atlantic during June is rare. Development is much more common late in the summer and typically occurs farther north.

"On record, there have only been three tropical systems to form this far south in the central Atlantic during June," Kottlowski said.

These systems were the Trinidad hurricane in 1933, Tropical Storm Ana in 1979 and Tropical Depression Two in 2000.

Should the system strengthen into a tropical storm prior to June 22, it would be the earliest named storm to form in this part of the Atlantic since official records were kept in 1851.
