A strong tropical wave east of the Windward Islands in the Atlantic has been weakening on Wednesday.

Chance of it developing into a tropical depression or tropical storm has decreased to 50% over the next 48 hours.

As of Wednesday afternoon, showers and thunderstorms associated with the disturbance have decreased, and satellite images have not shown any increase in convection near the circulation center.

The system is currently about 1,000 miles east of the southern Windward Islands. It will move close to the northern Leeward islands by Friday and could be near the Bahamas early next week. It's moving about 15 mph west-northwest.

Computer models posted by Weather Underground show the storm moving toward Puerto Rico and, eventually, the East Coast.

Depressions become tropical storms when sustained winds reach 39 mph and hurricanes when they reach 74 mph. The 2014 season has produced one named storm so far, Arthur, which developed into a hurricane before fizzling out near Nova Scotia, Canada.

Buoy reports in the Atlantic Ocean from SwellInfo.com predict waves of 9 feet in San Juan, Puerto Rico by the weekend with winds coming from the east-northeast. Those conditions would mean the storm has passed north of Puerto Rico and is moving toward Florida, Georgia and South Carolina.
