SUMMARY OF 100 PM CDT...1800 UTC...INFORMATION ---------------------------------------------- LOCATION...28.7N 93.6W ABOUT 80 MI...130 KM SSW OF CAMERON LOUISIANA MAXIMUM SUSTAINED WINDS...110 MPH...175 KM/H PRESENT MOVEMENT...NNE OR 15 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...963 MB...28.44 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Warning is in effect for... * High Island Texas to the Mouth of the Pearl River including Calcasieu Lake, Vermilion Bay, and Lake Borgne A Hurricane Warning is in effect for... * High Island Texas to Morgan City Louisiana A Tropical Storm Warning is in effect for... * West of High Island to Sargent Texas * East of Morgan City Louisiana to the mouth of the Pearl River, including New Orleans * Lake Pontchartrain and Lake Maurepas 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 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. 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 Hurricane Delta was located near latitude 28.7 North, longitude 93.6 West. Delta is now moving toward the north-northeast near 14 mph (22 km/h), and this motion should continue through Saturday morning. A turn toward the northeast is expected later on Saturday. On the forecast track, the center of Delta should make landfall along the coast of southwestern Louisiana during the next several hours, and then move across central and northeastern Louisiana tonight and Saturday morning. Maximum sustained winds are now near 110 mph (175 km/h) with higher gusts. Slow weakening is expected before landfall, with rapid weakening expected after the center moves inland. Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 160 miles (260 km). The Texas Coastal Ocean Observation Network station at Texas Point recently reported sustained winds of 50 mph (80 km/h) and a wind gust of 57 mph (92 km/h). Lake Charles Regional Airport recently reported a wind gust of 60 mph (96 km/h). The minimum central pressure estimated from Air Force Reserve Hurricane Hunter aircraft data is 963 mb (28.44 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 Morgan City, LA including Vermilion Bay...7-11 ft Holly Beach, LA to Rockefeller Wildlife Refuge, LA...5-8 ft Sabine Pass to Holly Beach, LA...3-5 ft Morgan City, LA to Port Fourchon, LA...4-7 ft Calcasieu Lake...2-4 ft High Island, TX to Sabine Pass...2-4 ft Port Fourchon, LA to the Mouth of the Pearl River...2-4 ft Lake Borgne...2-4 ft Lake Pontchartrain and Lake Maurepas...1-3 ft Mouth of the Pearl River, LA 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 It is important to note that small changes in the track, structure, or intensity of Delta could have large impacts on where the highest storm surge occurs. Users are urged to stay tuned for possible changes and updates. 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 this afternoon, with tropical storm conditions already occuring. Tropical storm conditions will continue to spread onshore within portions of the tropical storm warning areas during the next several hours. RAINFALL: Today through Saturday, Delta is expected to produce 5 to 10 inches of rain, with isolated maximum totals of 15 inches, from southwest into central Louisiana. These rainfall amounts will lead to significant flash, urban, small stream flooding, along with minor to major 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 the remnants of Delta move further inland, 1 to 3 inches of rain, with locally higher amounts, are expected in the Tennessee Valley and Mid Atlantic this weekend. There is a potential for 3 to 6 inches in the Southern Appalachians, which could lead to isolated flash, urban, and small stream flooding. TORNADOES: A few tornadoes are possible today and tonight over southern portions of Louisiana and Mississippi. SURF: Swells from Delta are affecting portions of the northern and western Gulf coast. 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 400 PM CDT. $$ Forecaster Beven
