The National Hurricane Center is issuing advisories on recently upgraded Hurricane Paulette and Tropical Depression Rene, both located over the central Atlantic Ocean, on Tropical Storm Sally, centered over the southeastern Gulf of Mexico, and on Tropical Depression Twenty, located over the eastern tropical Atlantic.
A surface trough over the west-central Gulf of Mexico is producing limited shower activity. While some slow development of this system is possible, strong upper-level winds associated with Tropical Storm Sally will probably limit the chances of tropical cyclone formation through Monday. The disturbance is forecast to move southwestward and then southward over the west-central and southwestern Gulf of Mexico through the next few days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.
Showers and thunderstorms located near and west of the Cabo Verde Islands are associated with a broad area of low pressure. Environmental conditions support some additional development, and a tropical depression could form over the far eastern tropical Atlantic during the next couple of days while the system moves slowly west-northwestward. By mid-week, however, upper-level winds should become less conducive for development.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.
A tropical wave is forecast to move off the west coast of Africa around mid-week. Some gradual development of the system will be possible thereafter as the disturbance moves slowly westward over the far eastern tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent. For more information, check the daily Tropical Weather Outlook, click here
