A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. 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 AM EST (1500 UTC), the center of Tropical Storm Eta was located near latitude 30.2 North, longitude 81.8 West. Eta is moving toward the north-northeast near 15 mph (24 km/h). A faster northeastward motion is expected over the next couple of days. On the forecast track, the center of Eta will emerge into the western Atlantic by early this afternoon. The cyclone is expected to accelerate over the western Atlantic and move parallel to, but offshore of the Carolinas tonight and early Friday before heading well east of the Mid-Atlantic coast by late Friday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Little change in strength is forecast through early Friday. Eta could re-intensify as a non-tropical cyclone late Friday or Friday night before becoming absorbed by a larger non-tropical cyclone on Saturday. Tropical-storm-force winds extend outward up to 115 miles (185 km) primarily over water to the east of the center. A NOAA Coastal Marine Observing site at St. Augustine Florida reported sustained winds of 39 mph (63 km/h) and a gust of 44 mph (70 km/h). A wind gust to 43 mph (69 km/h) was recently reported at the Mayport Naval Air Station near Jacksonville, Florida. The estimated minimum central pressure is 1003 mb (29.62 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. RAINFALL: Eta will produce an additional 1 to 3 inches of rain across portions of the Florida Peninsula through today, with isolated maximum storm total accumulations of 20 to 25 inches in South Florida. Localized flash and urban flooding will be possible across the Florida Peninsula today, especially across previously inundated areas. Minor river flooding is expected across portions of West Florida lasting into the weekend. WIND: Tropical storm conditions are expected in the Tropical Storm Warning area along the east coast of Florida through early this afternoon. SURF: Swells generated by Eta are expected to affect the Florida Gulf Coast today, and begin to affect portions of the coast of the southeastern United States later today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
