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 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 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, 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 Hurricane Zeta was located near latitude 24.3 North, longitude 91.5 West. Zeta is moving toward the northwest near 15 mph (24 km/h). A turn toward the north is expected overnight, and a faster northward to north-northeastward motion is expected today. On the forecast track, the center of Zeta will move over the central Gulf of Mexico overnight. Zeta is forecast to make landfall in southeastern Louisiana this afternoon, move close to the Mississippi coast this evening, and move across the southeastern and eastern United States on Thursday. Maximum sustained winds have increased to near 75 mph (120 km/h) with higher gusts. Additional strengthening is likely overnight and this morning, and Zeta is forecast to reach the northern Gulf Coast as a hurricane before weakening over the southeastern United States on Thursday. Hurricane-force winds extend outward up to 30 miles (50 km) from the center. Tropical-storm-force winds extend outward up to 140 miles (220 km) primarily to the east of the center. The latest minimum central pressure estimated from Air Force Reserve Hurricane Hunter aircraft data is 988 mb (29.18 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Zeta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT3.shtml. STORM SURGE: Along the northern Gulf Coast, 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... Mouth of the Pearl River to Dauphin Island AL...5-8 ft Port Fourchon LA to the Mouth of the Pearl River including Lake Borgne...4-6 ft Dauphin Island AL to AL/FL border including Mobile Bay...3-5 ft Mouth of the Atchafalaya River to Port Fourchon LA...2-4 ft AL/FL border to Navarre FL including Pensacola Bay...2-4 ft Lake Pontchartrain...2-4 ft Intracoastal City LA to the Mouth of the Atchafalaya River including Vermilion Bay...1-3 ft Navarre FL to Yankeetown FL including Choctawhatchee Bay and Saint Andrew Bay...1-3 ft The deepest water will occur along the immediate coast near and to the right of the landfall location, where the surge will be accompanied by large and dangerous 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. WIND: Hurricane conditions are expected within the Hurricane Warning area on the northern Gulf Coast this afternoon, with tropical storm conditions beginning later this morning. Tropical storm conditions are expected within the Tropical Storm Warning area on the northern Gulf Coast by late today, and tropical storm conditions are possible within the Tropical Storm Watch area this afternoon. Damaging winds, especially in gusts, will spread well inland across portions of southeast Mississippi and southern Alabama Wednesday night. RAINFALL: Locally heavy rains in advance of Zeta will continue to expand and move north from the central Gulf Coast this morning through today, eventually affecting the Ohio Valley to the central Appalachians tonight and Thursday. Meanwhile, the core of heavy rains near Zeta will track from the central Gulf Coast to the Mid-Atlantic late today through late Thursday. Rainfall totals of 2 to 4 inches with isolated amounts of 6 inches are expected across these areas, resulting in flash, urban, small stream, and minor river flooding. Zeta may produce an additional 1 to 2 inches of rain across portions of western Cuba and the northern Yucatan Peninsula through the early morning hours. TORNADOES: A few tornadoes are expected this afternoon into tonight over southeastern portions of Louisiana and Mississippi, southern Alabama, and the western Panhandle of Florida.
