Further out into the Atlantic, there are two tropical waves, but only one has a higher chance of becoming at least a tropical depression. Formation chance through 5 days is high, 90 percent, for the second Atlantic system.
Official National Hurricane Center Forecast
Showers and thunderstorms associated with a broad low pressure area and tropical wave located about 1300 miles east-southeast of the Windward Islands have become better organized since yesterday. However, recent satellite wind data indicates that the disturbance does not have a well-defined circulation. Environmental conditions appear generally favorable for continued development, and a tropical depression or storm is likely to form during the next day or two while the system moves west-northwestward at 20 to 25 mph.
Interests in the Lesser Antilles should closely monitor the progress of this system, as advisories on a potential tropical cyclone, accompanied by tropical storm watches for portions of this area, are likely to be issued later today.
* Formation chance through 48 hours…high…70 percent.
* Formation chance through 5 days…high…90 percent.
