DISCUSSION AND OUTLOOK ---------------------- At 100 PM EST (1800 UTC), the center of Tropical Storm Eta was located by satellites and NOAA Doppler weather radars near latitude 24.2 North, longitude 84.2 West. Eta is moving toward the southwest near 16 mph (26 km/h), and this motion with some reduction in forward speed is expected to continue through tonight. Little overall motion is forecast on Tuesday and a slow northward motion is expected on Wednesday. On the forecast track, the center of Eta will continue to move away from the Florida Keys and south Florida today, and will remain over the southeastern Gulf of Mexico tonight through Wednesday. Data from a recent Air Force Reserve reconnaissance mission and Doppler radars indicate that maximum sustained winds have decreased to near 50 mph (85 km/h) with higher gusts. Little change in strength is expected today and tonight. Some slight strengthening is forecast on Tuesday into Wednesday, followed by gradual weakening thereafter. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure based on recent reports from the aircraft is 995 mb (29.38 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 is expected to produce the following rainfall amounts through Saturday morning: The Bahamas: An additional 1 to 3 inches (25 to 75 mm), with isolated maximum storm totals of 15 inches (380 mm). Portions of Cuba: an additional 3 to 5 inches (75 to 125 mm), isolated maximum storm total accumulations of 25 inches (635 mm). Portions of the central and southern Florida peninsula, including the Keys: an additional 2 to 4 inches (50 to 100 mm)), with isolated maximum storm totals of 18 inches (450 mm) in South Florida. Flash flooding and river flooding will be possible in Cuba, along with landslides in areas of higher terrain. Life-threatening flash flooding will be possible across saturated urban areas of southeast Florida. Flash and urban flooding will also be possible for the Bahamas and the remainder of southern and eastern Florida over the next several days. Minor river flooding is also possible for central Florida. WIND: Gusty conditions will continue across the Florida Keys, south and central Florida, and the northwestern Bahamas today. Tropical storm conditions are possible in the Tropical Storm Watch area in Cuba tonight and Tuesday. TORNADOES: A tornado or two is possible today over parts of south Florida and the Keys. SURF: Swells generated by Eta are expected to affect the north coast of Cuba, the northwestern Bahamas, southern Florida and the Florida Keys during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
