Tropical Storm Harvey Public Advisory Number 31A

2017-08-28 07:50:06| National Hurricane Center (Atlantic)

Issued at 100 AM CDT Mon Aug 28 2017 000 WTNT34 KNHC 280549 TCPAT4 BULLETIN Tropical Storm Harvey Intermediate Advisory Number 31A NWS National Hurricane Center Miami FL AL092017 100 AM CDT Mon Aug 28 2017 ...LIFE-THREATENING FLOODING CONTINUES OVER SOUTHEASTERN TEXAS... ...DO NOT ATTEMPT TO TRAVEL IN THE AFFECTED AREAS IF YOU ARE IN A SAFE PLACE AND DO NOT DRIVE INTO FLOODED ROADWAYS...

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Mesquite Bay to High Island Catastrophic and life-threatening flooding continues in southeastern Texas, and flash flood emergencies are in effect for portions of this area. Please see warnings and other products issued by your local National Weather Service office for additional information on this life-threatening situation. Interests elsewhere along the upper Texas coast and in southwestern Louisiana should continue to monitor the progress of Harvey. 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 AM CDT (0600 UTC), the center of Tropical Storm Harvey was located near latitude 28.7 North, longitude 96.4 West. Harvey is moving toward the east-southeast near 3 mph (6 km/h) and a slow southeastward motion is expected today. A slow northeastward motion is expected to begin on Tuesday. On the forecast track, the center of Harvey is forecast to move off the middle Texas coast this morning, and remain just offshore through Tuesday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some slight restrengthening is possible after the center moves off the coast later today and Tuesday. Tropical-storm-force winds extend outward up to 140 miles (220 km) primarily over water to the east of the center. The estimated minimum central pressure is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Harvey is expected to produce additional rainfall accumulations of 15 to 25 inches through Friday over the upper Texas coast and into southwestern Louisiana. Isolated storm totals may reach 50 inches over the upper Texas coast, including the Houston/ Galveston metropolitan area. These rains are currently producing catastrophic and life-threatening flooding, and flash flood emergencies are in effect for portions of southeastern Texas. 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, Harvey is expected to produce total rain accumulations of 5 to 15 inches farther south into the middle Texas coast, farther west toward the Texas Hill Country, and farther east across south- central Louisiana. A list of 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... Port Aransas to Morgan City including Galveston Bay...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 in rain bands well to the east of the center of Harvey, including portions of the tropical storm warning area along the coast. Tropical storm conditions are likely to persist in areas of onshore winds within the warning area during the next couple of days. SURF: Swells generated by Harvey are 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 through Monday near the upper Texas coast and into far southwest Louisiana.
