SUMMARY OF 1000 PM EST...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...32.3N 79.0W ABOUT 65 MI...100 KM ESE OF CHARLESTON SOUTH CAROLINA MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H PRESENT MOVEMENT...NE OR 45 DEGREES AT 17 MPH...28 KM/H MINIMUM CENTRAL PRESSURE...1004 MB...29.65 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1000 PM EST (0300 UTC), the center of Tropical Storm Eta was located near latitude 32.3 North, longitude 79.0 West. Eta is moving toward the northeast near 17 mph (28 km/h) and this heading with an increase in forward speed is expected during the next day or two. On the forecast track, Eta is expected to gradually pull away from the southeast U.S. coast. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Eta could intensify a little as a non-tropical cyclone during the next day or so before it becomes absorbed by a larger non-tropical cyclone on Saturday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. An observation at Folly Beach Pier in South Carolina recently reported a wind gust of 54 mph (87 km/h). The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Rain bands extending southwest of Etas center will produce an additional 1 to 2 inches over portions of South Florida tonight, where isolated maximum storm total accumulations will range between 20 and 25 inches. Localized flash and urban flooding will be possible overnight, especially across previously inundated areas. Minor river flooding is expected across portions of West Florida lasting into the weekend. SURF: Swells generated by Eta will affect portions of the southeastern United States coast through Friday. These swells 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 400 AM EST. $$ Forecaster Cangialosi
