DISCUSSION AND OUTLOOK ---------------------- At 700 AM EST (1200 UTC), the center of Tropical Storm Eta was located near latitude 29.7 North, longitude 82.4 West. Eta is moving toward the northeast near 13 mph (20 km/h). Eta should move across northeastern Florida this morning and emerge into the western Atlantic this afternoon. The cyclone is expected to accelerate over the western Atlantic and move parallel to, but offshore of the Carolinas before heading well east of the Mid-Atlantic coast by late Friday. Maximum sustained winds have decreased to near 45 mph (75 km/h) with higher gusts. Eta could re-intensify as a non-tropical cyclone on Friday 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 recently reported sustained winds of 37 mph (59 km/h) and a gust of 44 mph (70 km/h) The estimated minimum central pressure is 1001 mb (29.56 inches) based on surface observations from Cedar Key. 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 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... Suwannee River to Middle of Longboat Key, FL including Tampa Bay...1-3 ft Water levels remain elevated and will gradually decrease throughout the day as the storm moves inland. 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 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 are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 1000 AM EST. $$ Forecaster Brown/Latto
