…Tropical Storm Watches in effect for southeast portions of South Central Texas…
…Tropical Storm Watches in effect for….Fayette, Gonzales, Wilson, Karnes, DeWitt, and Lavaca Counties…
Area of Concern:
Primarily areas east of Interstate 37 and east of Interstate 35. This includes the following counties of… Fayette, Gonzales, Wilson, Karnes, DeWitt, and Lavaca.
Word of caution…While the areas listed above will likely see the biggest impacts (Wind and Rain) from Harvey, small changes in the track/intensity, may push the impacts and tropical watches/warnings farther west to possibly include the I-35 corridor and the Austin-San Antonio metro areas.
Threats & Impacts:
Note…a change in track and intensity may dramatically change the impacts and locations of these threats/impacts.
Rainfall: 3-6 inches of rain east of Interstate 35 with isolated totals that may exceed 10 inches in the Tropical Storm Watch areas especially across the far eastern areas. Areas along and west of I-35 could see 1-3 inches. Flash Flooding and River Flooding is possible mainly across the Tropical Storm Watch area.
Winds: Tropical storm force winds of 40 to 50 mph are possible across the Watch area, with gusts that could exceed 60 mph. Areas to the west along the I-35 corridor may experience some low end tropical storm force wind gusts if bands push farther west.
Tornadoes: There may be a slight risk of tornadoes mainly along rain bands in the front right quadrant of landfall. These small tornadoes can happen day or night.
Timing and Overview:
The remnants of Harvey have reformed into a tropical depression just west of the Yucatan in the Bay of Campeche. Over the next couple of days Harvey is expected to strengthen into a strong Tropical Storm and make landfall along the middle Texas coast. On the current forecast track, tropical storm force winds are expected to affect southeast sections of South Central Texas on Friday and Saturday and have thus issued Tropical Storm Watches for this area (see County list above). As with any tropical system, flooding rainfall and strong winds will be the primary threat.
There remains uncertainty on exactly where the system could impact along the Texas coast and locations inland. As such please know that later updates may change the impact areas and threats. The system is forecast to move very slowly over SE Texas over the weekend.
It should be stressed that there is the potential for much higher rainfall amounts across South Central Texas if the center of system ends up tracking farther west and much lower amounts if the center of the system tracks toward the Upper Texas Coast.
At this time we urge you to remain closely aware of the changes to the forecast over the next 24-48 hours by monitoring the National Hurricane Center (www.hurricanes.gov) and your local forecast (www.weather.gov/sanantonio). As this system We expect greater detail and confidence in the forecast tomorrow.
Moderate for location and impacts of Harvey.
