DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the center of Tropical Storm Elsa was located near latitude 24.9 North, longitude 82.8 West. Elsa is moving toward the north-northwest near 10 mph (17 km/h) and a generally northward motion is expected today and tonight. A turn toward the north-northeast is expected on Wednesday, followed by a faster northeastward by late Thursday. On the forecast track, Elsa will continue to pass near the Florida Keys this morning, and move near or over portions of the west coast of Florida later today through tonight. On Wednesday morning, Elsa is forecast to make landfall along the north Florida Gulf coast and then move across the southeastern United States through Thursday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Slow strengthening is forecast through tonight, and Elsa could be near hurricane strength before it makes landfall in Florida. Weakening is expected after Elsa moves inland. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. A C-MAN station at Sand Key, Florida, recently measured a peak 1-minute sustained wind of 56 mph (90 km/h) gusting to 64 mph (104 km/h). The Key West International Airport also recently measured a peak sustained wind of 43 mph (69 km/h) gusting to 59 mph (95 km/h). The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Elsa can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5, WMO header WTNT45 KNHC and on the web at www.hurricanes.gov/graphics_at5.shtml?key_messages. WIND: Tropical storm conditions will continue over portions of the warning area in the Florida Keys through this evening. Tropical storm conditions are expected to spread northward into west-central Florida and the Florida Big Bend region tonight and early Wednesday, where hurricane conditions are possible. Tropical storm conditions are possible in the watch area in Georgia and South Carolina Wednesday night and early Thursday. STORM SURGE: The combination of a 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... Englewood, FL to Aucilla River including Tampa Bay...3 to 5 ft Bonita Beach, FL to Englewood, FL including Charlotte Harbor...2 to 4 ft Aucilla River to Ochlockonee River...2 to 4 ft Flamingo, FL to Bonita Beach, FL...1 to 3 ft Craig Key, FL to Dry Tortugas...1 to 2 ft Ochlockonee River to Indian Pass...1 to 2 ft Mouth of St. Marys River to South Santee River, SC...1 to 2 ft Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. RAINFALL: Across portions of Cuba through tonight, rainfall of 5 to 10 inches with isolated maximum amounts of 15 inches is expected. This will result in significant flash flooding and mudslides. Elsa is expected to produce the following rainfall amounts and impacts this week: Across the Florida Keys into southwest and western portions of the Florida Peninsula...3 to 5 inches with localized maximum totals up to 8 inches through Wednesday, which may result in considerable flash and urban flooding, along with minor to isolated moderate river flooding. Across the rest of Florida...2 to 4 inches with localized maximum totals up to 6 inches through Wednesday night, which may result in isolated flash, urban, and minor river flooding. Across portions of southeast Georgia and the Lowcountry of South Carolina, 3 to 5 inches with isolated maximum totals up to 8 inches will be possible, which may result in considerable flash and urban flooding. Across coastal portions of North Carolina into southeastern Virginia...1 to 3 inches with isolated totals up to 5 inches Wednesday night through Thursday night, which could lead to isolated flash and urban flooding.. TORNADOES: A few tornadoes are possible today through tonight across the Florida Peninsula. The tornado threat will continue on Wednesday across north Florida, southeast Georgia, and the Lowcountry of South Carolina. The tornado threat should shift to the eastern Carolinas and far southeast Virginia on Thursday. SURF: Swells will spread northward across portions of the Florida Keys and the west coast of Florida through early Wednesday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office for more details.
