SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Grand Isle Louisiana to the Alabama/Florida border * Metropolitan New Orleans and Lake Pontchartrain A Storm Surge Warning is in effect for... * Grand Isle Louisiana to the Okaloosa/Walton County Line Florida * Northern and western shores of Lake Pontchartrain A Tropical Storm Warning is in effect for... * Lake Maurepas * West of Grand Isle to Morgan City Louisiana * East of the Alabama/Florida border to Indian Pass Florida A Hurricane Watch is in effect for... * Lake Maurepas * East of the Alabama/Florida border to the Okaloosa/Walton County Line A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area, in this case within the next 24 hours. Preparations to protect life and property should be rushed to completion. A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 36 hours 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. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. 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. 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 48-HOUR OUTLOOK ------------------------------ At 400 PM CDT (2100 UTC), the center of Hurricane Nate was located near latitude 28.4 North, longitude 89.1 West. Nate is moving toward the north-northwest near 23 mph (37 km/h). A turn toward the north and a slight decrease in forward speed are expected during the next several hours, followed by a turn toward the north-northeast later tonight. A motion toward the northeast is expected on Sunday. On the forecast track, the center of Nate will pass near or over the mouth of the Mississippi River during the next few hours, then make landfall along the coasts of southeastern Louisiana or Mississippi tonight. After landfall, the center of Nate is expected to pass over portions of Mississippi, Alabama, and Tennessee late tonight through Sunday night. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Some strengthening is possible before landfall, and Nate could still become a category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale this evening. Rapid weakening is expected after landfall. 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. The NOAA automated station at Southwest Pass, Louisiana, recent reported sustained winds of 48 mph (78 km/h) and a wind gust of 60 mph (96 km/h) at an elevation of 125 feet. The estimated minimum central pressure is 981 mb (28.97 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Along the northern Gulf Coast, hurricane conditions are expected in the hurricane warning area in the next few hours, with tropical storm conditions currently 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. SURF: Swells generated by Nate will affect land areas around the Gulf of Mexico during the next day or so. 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 PM CDT. Next complete advisory at 1000 PM CDT. $$ Forecaster Beven

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 Hurricane Watch means that hurricane conditions are possible within the watch area. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere in western Cuba, the Yucatan Peninsula, and the northern coast of the Gulf of Mexico should monitor the progress of Nate. 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 1000 PM CDT (0300 UTC), the center of Tropical Storm Nate was located near latitude 22.3 North, longitude 86.4 West. Nate is moving toward the north-northwest near 22 mph (35 km/h), and this general motion is expected to continue through late Saturday. A turn toward the north is forecast Saturday night, followed by a turn toward north-northeast on Sunday. On the forecast track, the center of Nate will move across the Gulf of Mexico overnight and on Saturday, and will make landfall along the central U.S. Gulf coast Saturday evening or Saturday night. Reports from Air Force Reserve and NOAA Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 70 mph (110 km/h) with higher gusts. Additional strengthening is expected through Saturday up until the time Nate makes landfall along the northern Gulf coast. Tropical-storm-force winds extend outward up to 125 miles (205 km) primarily to the east of the center. A wind gust of 52 mph (84 km/h) was recently reported in Isabel Rubio in Pinar del Rio, Cuba. The minimum central pressure based on aircraft data is 990 mb (29.24 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to continue within the tropical storm warning area in Mexico during the next few hours. Tropical storm conditions are expected in the warning area in Cuba tonight, and are possible in the watch area in Cuba tonight. Along the northern Gulf Coast, hurricane conditions are expected in the hurricane warning area Saturday night, with tropical storm conditions expected by late Saturday. Tropical storm conditions are expected in the tropical storm warning area by Saturday night. Hurricane conditions are possible in the hurricane watch area Saturday night, and tropical storm conditions are possible in the tropical storm watch area Saturday night and Sunday. STORM SURGE: In the United States, 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... Morgan City, Louisiana to the mouth of the Mississippi River...4 to 6 ft Mouth of the Mississippi River to the Alabama/Florida border...5 to 8 ft Alabama/Florida border to the Okaloosa/Walton County Line...4 to 6 ft Okaloosa/Walton County Line to Indian Pass, Florida...2 to 4 ft Indian Pass to Crystal River, Florida...1 to 3 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. In Mexico, a storm surge will raise water levels by as much as 1 to 3 feet above normal tide levels along the immediate coast in areas of onshore winds on the Yucatan Peninsula and the adjacent islands. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Nate is expected to produce the following rain accumulations through Monday: Eastern Yucatan and western Cuba: 2 to 4 inches, max 6 inches. Eastern Belize and the Cayman Islands: 1 to 3 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 lower Ohio Valley into the central Appalachians: 2 to 4 inches, max 6 inches. TORNADOES: Isolated tornadoes will be possible beginning Saturday afternoon over parts of the central Gulf Coast region. SURF: Swells generated by Nate will affect land areas around the northwestern Caribbean during the next day or so. These swells are likely to cause life-threatening surf and rip current conditions.
