Tropical Storm Franklin formed late Sunday night in the western Gulf of Mexico.
Forecasters were also keeping an eye Sunday on another tropical disturbance in the Eastern Atlantic.
And although neither posed an immediate threat to Florida, “this is the time of year we never want to let our guard down,” said forecaster John Cangialosi at the National Hurricane Center.
Franklin prompted warnings and watches in Belize and Mexico.
As of 11 p.m. Sunday, Franklin was moving west-northwest at 13 miles an hour, forecasters said. Maximum sustained winds were about 40 mph.
The center is expected to move across the Yucatan Peninsula on Monday night and poses the greatest potential threat to residents near the coasts of of Honduras, Belize, and the Yucatan Peninsula, forecasters said.
In the Atlantic, an area of low pressure located about midway between the Cabo Verde Islands and the Lesser Antilles was described as elongated, with limited showers and thunderstorms. “Development, if any, is expected to be slow to occur as the system moves generally west-northwestward across the tropical Atlantic at about 15 mph,” the forecast advisory said.
Storm formation chances were 10 percent through 48 hours, and 30 percent over the next five days.
