For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area. Interests elsewhere in the Carolinas and the mid-Atlantic coast should monitor the progress of Elsa. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 800 AM EDT (1200 UTC), the center of Tropical Storm Elsa was located near latitude 24.5 North, longitude 82.6 West. Elsa is moving toward the north-northwest near 12 mph (19 km/h) and this general motion is expected to continue today, followed by a turn toward the north by tonight. A north-northeastward motion is expected on Wednesday. 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 northeastward across the southeastern United States through Thursday. Maximum sustained winds remain 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 wind gust of 52 mph (83 km/h). The Key West International Airport also recently measured a wind gust of 48 mph (77 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 should continue over portions of central and western Cuba during the next several hours. Tropical storm conditions are beginning in the warning area in the Florida Keys and are expected along the Florida west coast later today. 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 Florida beginning late tonight and in Georgia and South Carolina Wednesday night and early Thursday. STORM SURGE: A storm surge will raise water levels above normal tide levels by as much as the following amounts in areas of onshore winds within the Tropical Storm Warning areas... Southern coast of Cuba...2 to 4 ft 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 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.
