Heavy rainfall, tropical storm conditions and storm surge are possible for the Tampa Bay region from what's expected to be named Tropical Storm Debby this weekend, according to the National Hurricane Center. The Caribbean disturbance currently being monitored is not yet a "depression" or a "storm" — it is being called Potential Tropical Cyclone Four. It hasn't become organized enough to reach a higher status, but the designation allows forecasters to identify areas of disturbed weather close to land that are expected to become tropical cyclones. Potential Tropical Cyclone 4 is located about 315 miles southeast of Key West, Florida, and is moving to the west-northwest at 16 mph, according to the National Hurricane Center's latest update. The Tampa Bay region and much of Florida's west coast are within the hurricane center's cone of uncertainty, as seen below.
