Tropical Storm Bret has formed east of the Windward Islands, the National Hurricane Center said on Monday.

As of the 11 p.m. advisory, the tropical storm was located about 30 miles south of Trinidad.
The system was moving north northwest a 23 mph with maximum sustained winds of 40 mph.
"It's not expected to get much stronger than it already is heading out to the Caribbean Sea and perhaps becoming a remnant low as we're heading toward Wednesday," Local 10's chief certified meteorologist Betty Davis said.
A tropical storm warning was in effect for Trinidad, Tobago, Grenada and Venezuela, from Pedernales to Cumana, including Isla de Margarita.
The National Hurricane Center predicts that about 2 to 4 inches of rain will fall over the Windward Islands and the eastern coast of Venezuela on Monday and Tuesday.
