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. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. 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 Tropical Storm Watch means that tropical storm 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 OUTLOOK ---------------------- At 1000 AM CDT (1500 UTC), the center of Hurricane Delta was located near latitude 24.0 North, longitude 92.7 West. Delta is moving toward the northwest near 14 mph (22 km/h), and this motion with a reduction in forward speed is expected today. A turn toward the north is forecast to occur by late tonight, followed by a north- northeastward motion by Friday afternoon or Friday night. On the forecast track, the center of Delta will move over the central Gulf of Mexico today, over the northwestern Gulf of Mexico on Friday, and then move inland within the hurricane warning area Friday afternoon or Friday night. Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 105 mph (165 km/h) with higher gusts. Additional strengthening is forecast, and Delta is expected to become a major hurricane again by tonight. Some weakening is possible as Delta approaches the northern Gulf coast on Friday, with rapid weakening expected after the center moves inland. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The latest minimum central pressure reported by the Hurricane Hunter aircraft is 968 mb (28.59 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Delta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT1.shtml. 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 could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Rockefeller Wildlife Refuge, LA to Port Fourchon, LA including Vermilion Bay...7-11 ft Holly Beach, LA to Rockefeller Wildlife Refuge, LA...4-7 ft Port Fourchon, LA to the Mouth of the Mississippi River...4-6 ft Sabine Pass to Holly Beach, LA...3-5 ft Calcasieu Lake...3-5 ft High Island, TX to Sabine Pass...2-4 ft Mouth of the Mississippi River to Ocean Springs, MS...2-4 ft Lake Borgne, Lake Pontchartrain, and Lake Maurepas...2-4 ft Ocean Springs, MS to the AL/FL border including Mobile Bay...1-3 ft Sabine Lake...1-3 ft Port O'Connor, TX to High Island, TX including Galveston Bay... 1-3 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 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 by Friday afternoon or evening, with tropical storm conditions expected within this area by early Friday. Tropical storm conditions are expected within the tropical storm warning areas on Friday, and are possible in the tropical storm watch area Friday night. RAINFALL: Friday through Saturday, Delta is expected to produce 5 to 10 inches of rain, with isolated maximum totals of 15 inches, from southwest into south-central Louisiana. These rainfall amounts will lead to significant flash, urban, small stream flooding, along with minor to isolated moderate river flooding. For extreme east Texas into northern Louisiana, southern Arkansas and western Mississippi, Delta is expected to produce 3 to 6 inches of rain, with isolated maximum totals of 10 inches. These rainfall amounts will lead to flash, urban, small stream and isolated minor river flooding. As Delta moves farther inland, 1 to 3 inches of rain, with locally higher amounts, are expected in the Ohio Valley and Mid Atlantic this weekend. TORNADOES: A few tornadoes are possible late tonight through Friday over southern parts of Louisiana and Mississippi SURF: Swells from Delta will begin to affect portions of the northern and western Gulf coast later today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. Interests along the northern Gulf of Mexico coast should monitor the progress of Delta. Hurricane and Storm Surge Watches will likely be issued for a portion of this area later this morning. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 700 AM CDT (1200 UTC), the center of Hurricane Delta was located by satellite images and surface observation inland over northeastern Mexico near latitude 21.1 North, longitude 87.4 West. Delta is moving toward the northwest near 17 mph (28 km/h). A west-northwestward to northwestward motion is expected over the next day or so. A slower northwestward to north-northwestward motion is forecast to begin on Thursday, and a northward motion is likely Thursday night and Friday. On the forecast track, the center of Delta will move over the northeastern portion of the Yucatan Peninsula this morning. Delta is forecast to move over the southern Gulf of Mexico this afternoon, be over the southern or central Gulf of Mexico through Thursday, and approach the northern Gulf coast on Friday. Maximum sustained winds are near 105 mph (165 km/h) with higher gusts. Although some additional weakening is likely when Delta moves over the Yucatan peninsula this morning, re-strengthening is forecast when the hurricane moves over the southern Gulf of Mexico Wednesday night and Thursday, and Delta could become a category 4 hurricane again by late Thursday. Weakening is expected as Delta approaches the northern Gulf coast on Friday. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). A WeatherFlow observing site at Puerto Morelos, Mexico, has recently reported sustained winds of 54 mph (87 km/h) and a gust to 75 mph (122 km/h) after the passage of the center over that location. A wind gust to 64 mph (104 km/h) was recently reported on Cozumel, Mexico. The estimated minimum central pressure based on surface observations is 974 mb (28.76 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Delta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT1.shtml. STORM SURGE: A life-threatening storm surge will raise water levels in areas of onshore winds by as much as 6 to 9 ft above normal tide levels along the northern coast of the Yucatan Peninsula from Cabo Catoche to Progreso, and 5 to 7 ft above normal tide levels along the eastern coast of the Yucatan Peninsula from Tulum to Cabo Catoche. Near the coast, the surge will be accompanied by large and destructive waves. WIND: In the Yucatan Peninsula, dangerous hurricane conditions are expected in portions of the warning area during the next few hours, with tropical storm conditions already occuring. Tropical storm conditions are expected in the tropical storm warning area to continue for the next several hours. In Cuba, tropical storm conditions could continue over far western portions of the island during the next few hours. RAINFALL: Through early Thursday, Delta is expected to produce 4 to 6 inches of rain, with isolated maximum totals of 10 inches, across portions of the northern Yucatan Peninsula. This rainfall may result in areas of significant flash flooding. In addition, 2 to 4 inches of rain, with isolated higher amounts, are expected across portions of western Cuba. This rainfall may result in areas of flash flooding and mudslides. Friday through Saturday, Delta is expected to produce 4 to 8 inches of rain, with isolated maximum totals of 12 inches across portions of the central Gulf Coast north into portions of the Lower Mississippi Valley. These rainfall amounts will lead to flash, urban, and small stream flooding, along with minor river flooding. Heavy rainfall will eventually spread into the Tennessee Valley, and interior southeastern United States this weekend into early next week.
