Additional watches or warnings will likely be required on Tuesday.

On the forecast track, the center of the system is forecast to move across the northwestern Caribbean Sea through Tuesday night, and then over the eastern Gulf of Mexico on Wednesday and Thursday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is expected during the next few days, and the system is forecast to become a hurricane on Wednesday and continue strengthening on Thursday as it moves across the eastern Gulf of Mexico. * Formation chance through 48 hours...high ...90 percent. * Formation chance through 7 days...high...90 percent.

HAZARDS AFFECTING LAND ---------------------- Key Messages for Potential Tropical Cyclone Nine can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at hurricanes.gov/text/MIATCDAT4.shtml RAINFALL: Potential Tropical Cyclone Nine is expected to produce total rain accumulations of 4 to 8 inches over western Cuba and the Cayman Islands with isolated totals around 12 inches. Over the eastern Yucatan Peninsula, 2 to 4 inches of rain is expected with isolated totals over 6 inches. This rainfall brings a risk of considerable flooding. Over the Southeastern U.S., Potential Tropical Cyclone Nine is expected to produce total rain accumulations of 3 to 6 inches with isolated totals around 10 inches. This rainfall will likely result in areas of locally considerable flash and urban flooding, with minor to isolated moderate river flooding also possible. For a complete depiction of forecast rainfall associated with Potential Tropical Cyclone Nine, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at4.shtml?ero. STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Bonita Beach to Flamingo...2-4 ft Dry Tortugas...1-3 ft Florida Keys...1-3 ft Storm surge could raise water levels by as much as 2 to 4 feet above normal tide levels in areas of onshore winds along the southern coast of Pinar del Rio, Cuba, including the Isle of Youth. Storm surge could raise water levels by as much as 2 to 4 feet above ground level in areas of onshore winds within the warning area along the east coast of the Yucatan Peninsula. WIND: Hurricane conditions are possible within the watch areas in Cuba and Mexico by early Wednesday. Tropical storm conditions are expected in the warning areas in Cuba and Mexico beginning on Tuesday. Tropical storm conditions are possible in the watch area beginning on Wednesday. SURF: Swells generated by the system will affect the southern coast of Cuba and the Yucatan Peninsula of Mexico during the next couple of days. Swells will spread northward toward the west coast of Florida and the northeastern Gulf Coast on Wednesday and Thursday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
