SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Warning is in effect for... * Holly Beach Louisiana to Morgan City Louisiana A Storm Surge Watch is in effect for... * Sabine Pass Texas to west of Holly Beach Louisiana A Tropical Storm Warning is in effect for... * Sabine Pass Texas to Grand Isle Louisiana Catastrophic and life-threatening flooding continues in southeastern Texas and portions of southwestern Louisiana. Please see warnings and other products issued by your local National Weather Service office for additional information on this life-threatening situation. A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 12 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. 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 100 PM CDT (1800 UTC), the center of Tropical Storm Harvey was located near latitude 30.6 North, longitude 93.3 West. Harvey is moving erratically toward the north-northeast near 8 mph (13 km/h) and this general motion is expected to continue through Thursday. A turn toward the northeast is expected Thursday night and Friday. On the forecast track, the center of Harvey should move through southwestern and central Louisiana today and tonight, then move through northeastern Louisiana and northwestern Mississippi Thursday and Thursday night. Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts, mainly over water to the south and southeast of the center. Additional weakening is forecast during the next 48 hours as Harvey moves farther inland, and the cyclone is expected to weaken to a tropical depression tonight. Tropical-storm-force winds extend outward up to 80 miles (130 km) mainly to the south and southeast of the center. During the past few hours, there have been reports of wind gusts of 40-45 mph (65-70 km/h) in southwestern Louisiana and southeastern Texas near Cameron and Sabine Pass. The minimum central pressure based on surface observations is 995 mb (29.38 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Harvey is expected to produce additional rainfall accumulations of 3 to 6 inches from southwestern Louisiana and the adjacent border of eastern Texas northeastward into western Tennessee and Kentucky through Friday with isolated amounts up to 10 inches. The threat of heavy rains has ended in the Houston/ Galveston area. However catastrophic and life threatening flooding will continue in and around Houston, Beaumont/Port Arthur, eastward into southwest Louisiana for the rest of the week. The expected heavy rains spreading northeastward from Louisiana into western Kentucky may also lead to flash flooding and increased river and small stream flooding. DO NOT ATTEMPT TO TRAVEL IN THE AFFECTED AREA IF YOU ARE IN A SAFE PLACE. DO NOT DRIVE INTO FLOODED ROADWAYS. Please see warnings and products issued by your local National Weather Service office for additional information on this life-threatening situation. Elsewhere, the outer bands of Harvey are expected to produce additional rainfall amounts of 3 to 6 inches over portions of the central and eastern Gulf States and 2 to 4 inches farther north into parts of the Tennessee Valley, Ohio Valley and southern Mid Atlantic through Saturday. These rains may lead to flooding concerns across these areas. A list of preliminary rainfall observations compiled by the NOAA Weather Prediction Center can be found at: www.wpc.ncep.noaa.gov/discussions/nfdscc1.html 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... Holly Beach to Morgan City...2 to 4 ft San Luis Pass to west of Holly Beach incl. Galveston Bay...1 to 3 ft Morgan City to Grand Isle...1 to 3 ft The deepest water will occur along the immediate coast near the area of onshore winds. 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: Tropical storm conditions are occurring over portions of the warning area along the coast and are likely to persist through this afternoon. SURF: Swells generated by Harvey are still affecting the coasts of Texas and Louisiana. These swells are likely to cause life- threatening surf and rip current conditions. Please consult products from your local weather office. TORNADOES: A few tornadoes are possible today and tonight over parts of Louisiana, Mississippi, southern Alabama, and southeast Arkansas.
