A Storm Surge Watch has been issued from Port Bolivar, Texas, to Morgan City, Louisiana. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Mesquite Bay to Intracoastal City A Storm Surge Watch is in effect for... * Port Bolivar to Morgan City Catastrophic and life-threatening flooding continues in southeastern Texas. Please see warnings and other products issued by your local National Weather Service office for additional information on this life-threatening situation. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. Interests elsewhere along the middle and upper Texas coast and in southern 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 400 PM CDT (2100 UTC), the center of Tropical Storm Harvey was located near latitude 28.5 North, longitude 95.7 West. Harvey is moving toward the east-southeast near 3 mph (6 km/h), and a slow motion toward the southeast is expected through tonight. A gradual turn toward the northeast and a continued slow forward speed are expected Tuesday and Tuesday night. On the forecast track, the center of Harvey is expected to be just offshore of the middle and upper coasts of Texas through Tuesday night, then move inland over the northwestern Gulf coast on Wednesday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Little change in strength is forecast during the next 48 hours. Tropical-storm-force winds extend outward up to 175 miles (280 km) from the center. The National Ocean Service automated station at the Matagorda Bay entrance recently reported sustained winds of 46 mph (74 km/h) and a wind gust of 57 mph (92 km/h). The minimum central pressure estimated from surface observations along the Texas coast is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Harvey is expected to produce additional rainfall accumulations of 10 to 20 inches through Thursday over parts of the upper Texas coast 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 over large 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 and farther east across south-central Louisiana. Rainfall amounts of 5 to 10 inches are expected in southeast 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, and along the coast to the southwest of the center. Tropical storm conditions are likely to persist 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 Tuesday across southern Louisiana and extreme southeast Texas. NEXT ADVISORY ------------- Next intermediate advisory at 700 PM CDT.

12z Model Run
A tropical wave and associated low pressure area located a few hundred miles southeast of the Cabo Verde Islands is producing disorganized showers and thunderstorms. Environmental conditions are conducive for development, and a tropical depression could form in two or three days over the eastern Atlantic. The low is forecast to move westward at 15 to 20 mph over the tropical Atlantic during the next several days. Regardless of development, heavy rain is possible in portions of the Cabo Verde Islands through Wednesday. * Formation chance through 48 hours...medium...40 percent. * Formation chance through 5 days...high...80 percent. $$ Forecaster Blake
