48-HOUR OUTLOOK At 700 AM CDT (1200 UTC), the center of Hurricane Nate was located near latitude 25.7 North, longitude 88.0 West. Nate is moving toward the north-northwest near 22 mph (35 km/h). This general fast motion is expected to continue through tonight. A turn toward the north is forecast on Sunday morning. Then followed by a turn toward the north-northeast thereafter. The center of Nate will move across the central and northern Gulf of Mexico today. It will make landfall along the central U.S. Gulf coast tonight. Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 85 mph (135 km/h) with higher gusts. Some additional strengthening is possible before Nate makes landfall along the northern Gulf coast.
HAZARDS AFFECTING LAND
Along the northern Gulf Coast, hurricane conditions are expected in the hurricane warning area tonight. Tropical storm conditions expected to begin by this afternoon.
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. That is if the peak surge occurs at the time of high tide Morgan City, Louisiana to the mouth of the Mississippi River4 to 6 ft Mouth of the Mississippi River to the Alabama/Florida border5 to 9 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. 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. It 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: 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 4 inches, max 6 inches.
TORNADOES: Isolated tornadoes will be possible beginning later today over parts of the central Gulf Coast region. SURF: Swells generated by Nate will affect land areas around the western 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.
