Additional watches or warnings may be required later today. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. 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. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 500 AM EDT (0900 UTC), the center of Hurricane Isaias was located near latitude 23.9 North, longitude 77.1 West. Isaias is moving toward the northwest near 12 mph (19 km/h), and a general northwestward motion with some decrease in forward speed is expected for the next day or so, followed by a turn toward the north-northwest by late Sunday. On the forecast track, the center of Isaias will move near or over the Central Bahamas this morning, near or over the Northwestern Bahamas later today and near the east coast of the Florida peninsula tonight through Sunday. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Little change in strength is expected through Sunday, and and Isaias is forecast to remain a hurricane during this time. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 988 mb (29.18 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Isaias 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 dangerous 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... Jupiter Inlet to Ponte Vedra Beach FL...2-4 ft North Miami Beach to Jupiter Inlet FL...1-3 ft The deepest water will occur along the immediate coast near and to the right of the center, where the surge will be accompanied by large 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. A dangerous storm surge will raise water levels by as much as 3 to 5 feet above normal tide levels in areas of onshore winds in the Bahamas. WIND: Hurricane conditions are occurring over portions of the Central Bahamas and will spread over the Northwestern Bahamas later today. Hurricane conditions are expected to reach the coast within the hurricane warning area in Florida tonight and will spread northward through Sunday. Winds are expected to first reach tropical storm strength later today, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Tropical storm conditions are expected within the tropical storm warning area, and are possible within the watch area, over southern Florida by this afternoon or evening. RAINFALL: Isaias is expected to produce the following rain accumulations: Bahamas: 4 to 8 inches. Cuba: 1 to 2 inches, with isolated maximum totals of 4 inches. These rainfall amounts could lead to life-threatening flash and urban flooding, especially in low-lying and poorly drained areas. From Friday night through Tuesday: South Florida into east-Central Florida: 2 to 4 inches, with isolated maximum totals of 6 inches. Northeast Florida into coastal Georgia: 1 to 2 inches. Carolinas into the mid Atlantic, including the southern and central Appalachians: 2 to 4 inches, with isolated maximum totals of 6 inches. Heavy rainfall from Isaias could result in potentially life-threatening flash and urban flooding, especially in low-lying and poorly drained areas. Minor river flooding is possible across portions of the Carolinas and into Virginia. SURF: Swells generated by Isaias are affecting portions of Hispaniola, eastern Cuba, the Turks and Caicos, and the southeastern and central Bahamas. These swells will spread along the east coast of Florida and the southeastern United States coast today. 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 800 AM EDT. Next complete advisory at 1100 AM EDT. $$ Forecaster Beven
