SUMMARY OF 100 AM CDT...0600 UTC...INFORMATION ---------------------------------------------- LOCATION...28.6N 86.1W ABOUT 115 MI...185 KM SSW OF PANAMA CITY FLORIDA MAXIMUM SUSTAINED WINDS...65 MPH...100 KM/H PRESENT MOVEMENT...NW OR 315 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...990 MB...29.23 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Watch is in effect for... * Crystal River to Navarre Florida A Tropical Storm Warning is in effect for... * Suwannee River to the Mississippi/Alabama border 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. 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. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the center of Subtropical Storm Alberto was located near latitude 28.6 North, longitude 86.1 West. The storm is moving toward the northwest near 9 mph (15 km/h). A north- northwestward to northward motion is expected during the next few days. On the forecast track, the center of Alberto will cross the northern Gulf Coast in the warning area by this afternoon. The weakening system is forecast to move well inland into the Tennessee Valley on Tuesday and into the Ohio Valley and Great Lakes region on Wednesday and Thursday. Maximum sustained winds remain near 65 mph (100 km/h) with higher gusts. Little change in strength is expected before Alberto reaches the northern Gulf Coast later today. Steady weakening is forecast after landfall, and Alberto will likely become a subtropical depression tonight or early Tuesday and degenerate into a remnant low by Tuesday afternoon. Winds of 40 mph extend outward up to 115 miles (185 km) from the center. NOAA buoy 42039 in the northeastern Gulf of Mexico recently reported a sustained wind of 49 mph (79 km/h) with a gust to 61 mph (98 km/h). The estimated minimum central pressure based on aircraft and buoy observations is 990 mb (29.23 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Alberto is expected to produce the following rain accumulations through Tuesday: Central Cuba...Additional 5 to 10 inches, isolated storm-totals of 20 to 25 inches. The Florida panhandle into much of Alabama and western Georgia...4 to 8 inches, isolated 12 inches. The Florida Keys and south Florida...Additional 3 to 6 inches, isolated storm totals of 10 inches. Rest of the Florida peninsula...1 to 4 inches. Rest of the Southeast and Tennessee Valley into the lower mid Atlantic from Tennessee east through the Carolinas...2 to 6 inches. Rains in Cuba could produce life-threatening flash floods and mudslides. Flooding and flash flooding are possible in the southeast United States, including Florida. WIND: Tropical storm conditions will spread across the warning area throughout the day. STORM SURGE: The combination of 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... Crystal River to Navarre Florida...2 to 4 ft The deepest water will occur along the immediate coast. 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. TORNADOES: A couple of brief tornadoes are possible today across much of Florida, central and southern Georgia, southern South Carolina, and southeastern Alabama. SURF: Swells generated by Alberto will continue to affect the eastern and northern Gulf Coast through Tuesday. These swells are likely to cause life-threatening surf and rip current conditions. For more information, consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Cangialosi

CROIX MAXIMUM SUSTAINED WINDS...155 MPH...250 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...942 MB...27.82 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Guadeloupe * Dominica * St. Kitts, Nevis, and Montserrat * U.S. Virgin Islands * British Virgin Islands * Puerto Rico, Culebra, and Vieques A Tropical Storm Warning is in effect for... * Antigua and Barbuda * Saba and St. Eustatius * St. Maarten * Anguilla * St. Lucia * Martinique A Hurricane Watch is in effect for... * Saba and St. Eustatius * St. Maarten * St. Martin and St. Barthelemy * Anguilla * Isla Saona to Puerto Plata A Tropical Storm Watch is in effect for... * St. Vincent and the Grenadines * West of Puerto Plata to the northern Dominican Republic-Haiti border A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. 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 Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere in Hispaniola, the southeastern Bahamas, and the Turks and Caicos Islands should monitor the progress of Maria. Additional watches and warnings may be required today. 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 the United States, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 200 AM AST (0600 UTC), the center of Hurricane Maria was located near latitude 15.7 North, longitude 61.9 West. Maria is moving toward the west-northwest near 9 mph (15 km/h), and this general motion is expected to continue through Wednesday. On the forecast track, the eye of Maria will move over the northeastern Caribbean Sea today, and approach the Virgin Islands and Puerto Rico tonight and Wednesday. Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that the maximum sustained winds have decreased only slightly, to near 155 mph (250 km/h) with higher gusts. Maria is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are likely during the next day or two, but Maria is forecast to remain an extremely dangerous category 4 or 5 hurricane while it approaches the Virgin Islands and Puerto Rico. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The minimum central pressure estimated from reconnaissance data is 942 mb (27.82 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Winds over Dominica are diminishing. Hurricane conditions should spread throughout portions of the hurricane warning area in the Leeward Islands this morning. Hurricane conditions should spread through the remainder of the Hurricane Warning area later today and Wednesday. Hurricane conditions are possible within the Hurricane Watch area in the Dominican Republic late Wednesday, with tropical storm conditions possible by early Wednesday. Tropical storm conditions are possible in the Tropical Storm Watch area in St. Vincent and the Grenadines this morning, and are possible in the Tropical Storm Watch area in the Dominican Republic on Wednesday. Wind speeds atop and on the windward sides of hills and mountains could be much stronger than the near-surface winds indicated in this advisory. STORM SURGE: A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 7 to 11 feet above normal tide levels in the hurricane warning area near where the center of Maria moves across the Leeward Islands and the British Virgin Islands. 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 is expected to reach the following heights above ground if the peak surge occurs at the time of high tide... Puerto Rico and the U.S. Virgin Islands...6 to 9 ft The deepest water will occur along the immediate coast near and to the north and east of the landfall location, where the surge will be accompanied by large and destructive 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. RAINFALL: Maria is expected to produce the following rain accumulations through Thursday: Central and southern Leeward Islands...10 to 15 inches, isolated 20 inches. U.S. and British Virgin Islands...10 to 15 inches, isolated 20 inches. Puerto Rico...12 to 18 inches, isolated 25 inches. Northern Leeward Islands from Barbuda to Anguilla...4 to 8 inches, isolated 10 inches. Windward Islands and Barbados...2 to 4 inches, isolated 6 inches. Eastern Dominican Republic...4 to 8 inches, isolated 12 inches. Rainfall on all of these islands could cause life-threatening flash floods and mudslides. SURF: Swells generated by Maria are affecting the Lesser Antilles. 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 500 AM AST. $$ Forecaster Pasch
