The National Hurricane Center is also issuing advisories on recently upgraded Tropical Storm Sally, located near southern Florida.

Satellite imagery and satellite-derived wind data indicate that the area of low pressure located several hundred miles west-southwest of the Cabo Verde Islands has become better defined. The associated shower and thunderstorm activity is also becoming better organized. If this development trend continues, then a tropical depression will likely form later today or tonight. The system is expected to move westward then northwestward across the eastern and central tropical Atlantic over the next several days. * Formation chance through 48 hours...high...90 percent. * Formation chance through 5 days...high...90 percent. Showers and thunderstorms located near the Cabo Verde Islands are associated with a broad area of low pressure that has developed along a tropical wave. Environmental conditions support some additional development during the next few days, and a tropical depression could form over the far eastern tropical Atlantic early next week while the system moves slowly west-northwestward. By mid-week, upper-level winds could become less conducive for development. * Formation chance through 48 hours...medium...40 percent. * Formation chance through 5 days...medium...60 percent. && Public Advisories on Sally are issued under WMO header WTNT34 KNHC and under AWIPS header MIATCPAT4.
