A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, in this case within 24 hours in the indicated locations. 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 Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in this case within 24 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 along the Gulf Coast of Florida should monitor the progress of Eta. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 1000 PM EST (0300 UTC), the center of Tropical Storm Eta was located near latitude 28.3 North, longitude 83.4 West. Eta is moving toward the north near 12 mph (19 km/h), and this general motion is expected to continue overnight, followed by a turn toward the north-northeast and northeast Thursday morning. On the forecast track, the center of Eta will move near but just offshore of the west-central coast of Florida during the next few hours, and move inland over the northern portion of the Florida peninsula on Thursday morning. Eta is expected to move northeastward into the western Atlantic late Thursday and early Friday. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Slow weakening is expected as Eta approaches the west coast of Florida tonight, followed by more rapid weakening after landfall occurs on Thursday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. Albert Whitted Airport near St. Petersburg recently reported sustained winds of 40 mph (64 km/h) and a gust of 52 mph (84 km/h). A Weatherflow site in Tampa Bay recently measured sustained winds of 45 mph (72 km/h) and a gust of 59 mph (94 km/h). The minimum central pressure reported by an Air Force Hurricane Hunter aircraft is 993 mb (29.33 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Eta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml. 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... Anclote River to Boca Grande, FL including Tampa Bay...3-5 ft Boca Grande, FL to Bonita Beach, FL including Charlotte Harbor...2-4 ft Steinhatchee River to Anclote River...2-4 ft Bonita Beach to Flamingo...1-2 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. 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: Eta is expected to produce the following rainfall totals: West and central Florida, through Thursday: 2 to 4 inches, with maximum storm total accumulations of 6 inches. North and South Florida, through Thursday: An additional 1 to 2 inches, with isolated maximum storm total accumulations of 4 inches in North Florida and 20 to 25 inches in South Florida. Additional flash and urban flooding will be possible in South Florida through Thursday, especially across previously inundated areas. Flash, urban, and isolated minor river flooding is expected across portions of West and North Florida through Thursday. WIND: Tropical storm conditions are expected in the Tropical Storm Warning area along the Florida west coast through Thursday morning. Tropical storm conditions are possible in the watch area along the Florida Big Bend region on Thursday. TORNADOES: A few tornadoes are possible overnight over parts of western and central Florida. SURF: Swells generated by Eta are expected to affect the north coast of Cuba, southern and western Florida, and the Florida Keys during the next day or so. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
