For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. 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 PM CDT (1800 UTC), the center of Subtropical Storm Alberto was located near latitude 29.8 North, longitude 85.9 West. The storm is moving toward the north near 8 mph (13 km/h). A faster northward or north-northwestward 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 this afternoon or this evening. After landfall, the 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 are near 50 mph (85 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 105 miles (165 km) from the center. An automated weather observing site near Panama City recently reported sustained winds of 36 mph (57 km/h) with a gust to 56 mph (91 km/h). A sustained wind of 38 mph (61 km/h) with a gust to 44 mph (70 km/h) was recently observed near Apalachicola. The estimated minimum central pressure from reconnaissance aircraft data is 994 mb (29.35 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 across eastern and central Alabama and western Georgia...4 to 8 inches, isolated 12 inches. The Florida Keys and Florida peninsula...Additional 1 to 3 inches, isolated 10 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 continue within portions of the warning area into this evening. 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... Suwannee River to Mexico Beach...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 from northern Florida into 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 PM CDT. $$ Forecaster Brown

DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 PM CDT (0000 UTC), NOAA Doppler radar data indicate that the center of Hurricane Nate is now making landfall at the mouth of the Mississippi River, near latitude 29.0 North, longitude 89.2 West. Nate is now moving toward the north and a little slower, near 20 mph (31 km/h). A turn toward the north-northeast is expected later tonight, followed by a motion toward the northeast on Sunday. On the forecast track, the center of Nate will make a second landfall along the coast of Mississippi tonight. After landfall, the center of Nate is expected to pass over portions of Mississippi, Alabama, and Tennessee late tonight through Sunday night. Aircraft reconnaissance data and Doppler radar velocity data indicate that maximum sustained winds have decreased to near 85 mph (140 km/h) with higher gusts. Strengthening now appears unlikely before Nate's center reaches the Mississippi coast during the next few hours. Rapid weakening is expected after landfall, with Nate becoming a tropical depression by Sunday night. Hurricane-force winds extend outward up to 40 miles (65 km) from the center, and tropical-storm-force winds extend outward up to 125 miles (205 km) mainly to the east of the center. A sustained wind of 54 mph (87 km/h) and a gust to 58 mph (94 km/h) were recently reported by NOAA buoy 42040 to the east of the mouth of the Mississippi River. The minimum central pressure based on aircraft data is 982 mb (29.00 inches). A water level of 2.9 ft above Mean Higher High Water (MHHW) was recently reported by a National Ocean Service gauge at Pilots Station East, Southwest Pass, Louisiana. HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in the hurricane warning area in the next few hours, with tropical storm conditions already spreading onshore. Tropical storm conditions are expected in the tropical storm warning area tonight and Sunday morning. Hurricane conditions are possible in the hurricane watch area tonight. 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 is expected to reach the following heights above ground if the peak surge occurs at the time of high tide... Mouth of the Mississippi River to the Mississippi/Alabama border...7 to 11 ft Mississippi/Alabama border to the Alabama/Florida border, including Mobile Bay...6 to 9 ft Alabama/Florida border to the Okaloosa/Walton County Line...4 to 6 ft Grand Isle, Louisiana to the mouth of the Mississippi River...2 to 4 ft Okaloosa/Walton County Line to Indian Pass, Florida...2 to 3 ft Indian Pass to Crystal River, Florida...1 to 3 ft Morgan City, Louisiana to Grand Isle...1 to 2 ft The deepest water will occur along the immediate coast near and to the 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: Nate is expected to produce the following rain accumulations through Monday: Western Cuba: 2 to 4 inches, max 6 inches. East of the Mississippi River from the central Gulf Coast into the Deep South, eastern Tennessee Valley, and southern Appalachians: 3 to 6 inches, max 10 inches. Across the Ohio Valley into the central Appalachians: 2 to 5 inches, max 7 inches. TORNADOES: A few tornadoes are possible across parts of Alabama, the western Florida Panhandle, western Georgia, and southern Mississippi through Sunday afternoon.

The Government of France has changed the Hurricane Warning for Guadeloupe to a Tropical Storm Warning, and has discontinued the Tropical Storm Warning for Martinique. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Dominica * St. Kitts, Nevis, and Montserrat * U.S. Virgin Islands * British Virgin Islands * Puerto Rico, Culebra, and Vieques * Cabo Engano to Puerto Plata A Tropical Storm Warning is in effect for... * Antigua and Barbuda * Saba and St. Eustatius * St. Maarten * Anguilla * Guadeloupe * West of Puerto Plata to the northern border of the Dominican Republic and Haiti * West of Cabo Engano to Punta Palenque A Hurricane Watch is in effect for... * Saba and St. Eustatius * St. Maarten * St. Martin and St. Barthelemy * Anguilla * Isla Saona to Cabo Engano 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. 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 PM AST (1800 UTC), the eye of Hurricane Maria was located near latitude 16.6 North, longitude 63.6 West. Maria is moving toward the west-northwest near 10 mph (17 km/h), and this general motion is expected to continue through Wednesday night. On the forecast track, the eye of Maria will move over the northeastern Caribbean Sea today, and then pass near or over the Virgin Islands overnight and Puerto Rico on Wednesday. Maximum sustained winds are near 160 mph (260 km/h) with higher gusts. Maria is a potentially catastrophic category 5 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 until it moves near or over the Virgin Islands and Puerto Rico. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). During the past few hours, the eye passed just north of NOAA buoy 42060, which reported 1-min average winds of 85 mph (137 km/h) and a wind gust of 94 mph (151 km/h). The estimated minimum central pressure is 927 mb (27.37 inches). NOAA buoy 42060 reported a minimum pressure of 955.7 mb (28.22 inches) as the eye passed. HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions will continue in portions of the hurricane warning area in the Leeward Islands this afternoon, and spread into the Virgin Islands and Puerto Rico tonight and Wednesday. Tropical storm conditions are occuring over the remainder of the Leeward Islands, and should spread into the Virgin Islands and Puerto Rico starting in the next several hours. Hurricane conditions are expected within the hurricane warning area in the Dominican Republic late Wednesday, with tropical storm conditions expected by early Wednesday. Tropical storm conditions are expected in the tropical storm warning areas in the Dominican Republic on Wednesday. Wind speeds atop and on the windward sides of hills and mountains and on high-rise buildings 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 will 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 PM AST. Hourly Tropical Cyclone Updates will commence at 300 PM AST as the eye is now well-defined in data from the San Juan Doppler radar. $$ Forecaster Beven
