DISCUSSION AND OUTLOOK ---------------------- At 600 AM CST (1200 UTC), the center of Tropical Storm Eta was located near latitude 22.6 North, longitude 85.3 West. Eta has been drifting southward this morning, but it is expected to become stationary again later today. A slow northward motion is forecast to begin tonight and continue through Thursday. Maximum sustained winds have increased to near 60 mph (100 km/h) with higher gusts. Additional strengthening is forecast during the next day or two, followed by weakening likely starting on Thursday. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 992 mb (29.29 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 today and tonight: Western Cuba: an additional 3 to 5 inches (75 to 125 mm), with isolated maximum storm total accumulations of 25 inches (765 mm). South Florida: an additional 1 to 2 inches (25 to 50 mm), with isolated maximum storm total accumulations of 20 inches (510 mm). Flash and river flooding will be possible in western Cuba, along with landslides in areas of higher terrain. Additional flash and urban flooding, especially across previously inundated areas, will be possible in South Florida today and tonight. WIND: Tropical storm conditions are possible in the Tropical Storm Watch area in Cuba today. 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 day or so. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
