TAMPA, Fla. (WFLA)—Tropical Storm Erin continues to move westward as it is expected to become a hurricane in a couple of days, the National Hurricane Center said.

Erin is located about 1400 miles east of the northern Leeward Islands and is moving toward the west near 20 mph.

According to NHC, the movement is expected to continue into Thursday, with a west-northwestward motion beginning Thursday and continuing into the weekend.

The center of Erin is expected to move near or just north of the northern Leeward Islands over the weekend.

Gradual strengthening is forecasted beginning today, and Erin is expected to become a Hurricane by late Thursday or early Friday.

Maximum sustained winds are 45 mph.

There are no coastal watches or warnings in effect at this time.

A tropical wave over the northwestern Caribbean Sea is producing showers and thunderstorms this morning, the National Hurricane Center said.

The system is expected to move west-northwestward and will cross the Yucatan Peninsula today with no increase in organization.

The NHC said some development is possible after the system emerges across the southwestern Gulf beginning Thursday as it moves to the west-northwest or northwest at 10 to 15 mph.

The chance of formation in the next 48 hours is 10 percent, while in the next seven days it is 20 percent.

A non-tropical area of low pressure a few hundred miles from Nova Scotia, Canada, is producing showers and thunderstorms.

Limited tropical or subtropical development is possible today as the low lingers near the warm waters of the Gulf Stream, the NHC said.

By tonight, the system is expected to move northward over cooler waters, which will stop the chances of any tropical development.

The chance of development in the next 48 and seven days is 10 percent.
