TAMPA, Fla. (WFLA)— A Tropical Storm watch is in effect for portions of the northern Leeward Islands as Jerry continues to move quickly west-northwestward, the National Hurricane Center said.

Jerry is located about 890 miles east-southeast of the northern Leeward Islands and is moving toward the west-northwest at about 23 mph.

According to the NHC, Jerry is expected to continue in this general motion with a decrease in forward speed during the next few days before turning toward the north-northwest on Friday.

The core of the system is expected to be near or to the north of the northern Leeward Islands late Thursday and Friday.

Maximum sustained winds are near 50 mph.

Strengthening is expected during the next few days, and Jerry is expected to become a hurricane on Thursday.

A large area of disorganized showers and thunderstorms over the Bay of Campeche is being caused by a trough of low pressure.

Slow development of this system is possible before it moves inland over southern Mexico later today and early Thursday, the NHC said.

Regardless of development, parts of southern Mexico could see heavy rain and gusty winds over the next day or so.

The chance of development in the next 48 hours is 10 percent.

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