SUMMARY OF 400 AM EST...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...18.3N 84.9W ABOUT 250 MI...405 KM WSW OF GRAND CAYMAN MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...ENE OR 60 DEGREES AT 10 MPH...17 KM/H MINIMUM CENTRAL PRESSURE...1002 MB...29.59 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The government of the Bahamas has upgraded the Tropical Storm Watch to a Tropical Storm Warning for the northwestern Bahamas. The Tropical Storm Watch along the east coast of Florida has been extended northward to Sebastian Inlet. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * The Cayman Islands * The Cuban provinces of Camaguey, Ciego de Avila, Sancti Spiritus, Villa Clara, Cienfuegos, and Matanzas. * Northwestern Bahamas, including the Abacos, Andros Island, Berry Islands, Bimini, Eleuthera, Grand Bahama Island, and New Providence. A Tropical Storm Watch is in effect for... * The Cuban provinces of La Habana, Artemisa y Mayabeque, Pinar del Rio, and the Isle of Youth. * Sebastian Inlet southward around the Florida peninsula to Bonita Beach * Lake Okeechobee * Florida Keys * Florida Bay A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere in Cuba and the Florida peninsula should monitor the progress of this system as additional Tropical Storm Watches or Warnings could be required for some of these areas later today. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 400 AM EST (0900 UTC), the center of Tropical Depression Eta was located near latitude 18.3 North, longitude 84.9 West. The depression is moving toward the east-northeast near 10 mph (17 km/h). An east-northeast to northeast motion at a faster forward speed is expected through early Sunday. A turn toward the north and northwest are expected by Sunday afternoon. On the forecast track, the center of Eta will approach the Cayman Islands later today, be near central Cuba tonight and Sunday, and near the Florida Keys or south Florida Sunday night and Monday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Eta is forecast to become a tropical storm again later today, with further strengthening likely through Sunday. The estimated minimum central pressure is 1002 mb (29.59 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 Thursday morning: Portions of Central America: An additional 2 to 5 inches (50 to 125 mm), isolated maximum storm totals of 40 inches (1000 mm) in eastern Honduras and eastern Nicaragua. Jamaica: An additional 2 to 4 inches (50 to 125 mm), isolated maximum storm totals of 15 inches (380 mm). The Cayman Islands into portions of Cuba: an additional 5 to 10 inches (125 to 255 mm), isolated storm totals of 25 inches (650 mm). The Bahamas and portions of the Florida peninsula, including the Keys: 5 to 10 inches (125 to 255 mm), isolated maximum totals of 15 inches (380 mm). The threat of life-threatening flooding will continue across portions of Central America, along with landslides in areas of higher terrain. Significant, life-threatening flash and river flooding will be possible in Cuba, along with landslides in areas of higher terrain. Flash and urban flooding will also be possible for the Cayman Islands, Jamaica, the Bahamas, and Southern Florida. STORM SURGE: A dangerous storm surge will raise water levels by as much as 2 to 4 feet above normal tide levels along the coast of Cuba near and to the east of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. 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... Marco Island, FL to North Miami Beach, FL including Biscayne Bay...2-3 ft Florida Keys...2-3 ft North Miami Beach, FL to Flagler/Volusia County Line, FL...1-2 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. 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. WIND: Tropical storm conditions are expected in the Cayman Islands this afternoon and evening, in the warning area in Cuba tonight and Sunday, and in the northwestern Bahamas on Sunday. Tropical storm conditions are possible in the watch area in Cuba tonight and Sunday and in the watch area in south Florida and the Florida Keys by late Sunday. TORNADOES: A tornado or two may occur Sunday evening and Sunday night over south Florida and the Keys. SURF: Swells generated by Eta are expected to spread northeastward and affect the Cayman Islands, Jamaica, the southern coast of Cuba, the northwestern Bahamas, and 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. NEXT ADVISORY ------------- Next intermediate advisory at 700 AM EST. Next complete advisory at 1000 AM EST. $$ Forecaster Cangialosi
