This system is is moving to the west-nothwest at around 18 mph, and is expected to reach land by midday today. Observations from offshore marine buoys are indicating sustained winds around 25-35 mph, with gusts to 40 mph. Locally heavy rainfall, strong winds and hazardous coastal and marine conditions remain the primary concerns with this system. The threats include: - Flash Flooding: Moderate threat of flash flooding mainly south and west of I-37, especially in urban areas. Rainfall accumulations 3 to 5" with locally up to 7" through early Wednesday. - Hazardous Seas: Wave heights 10 to 13 feet with occasionally up to 16 feet. - Tornadoes: Isolated tornadoes are possible across South Texas, especially in outer rain bands. - Coastal Flooding: Moderate coastal flooding is expected with up to 3 ft of inundation possible across the Middle Texas Coast south of Matagorda Bay. - Rip Currents: High risk of rip currents across all of the Texas Coast. - Strong Winds: Tropical Storm force winds of sustained 40-50 mph with gusts up to 60-70 mph are possible in the warned areas. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Prepare for dangerous rainfall flooding having possible significant impacts across southern Brush Country and southern Coastal Bend. Potential impacts include: - Moderate rainfall flooding may prompt several evacuations and rescues. - Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, canals, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures. Prepare for locally hazardous rainfall flooding having possible limited impacts across northern portions of the Brush Country and the rest of the Coastal Plains. * WIND: Protect against hazardous wind having possible limited impacts across South Texas. Potential impacts include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over. - A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. - Scattered power and communications outages. * TORNADOES: Prepare for a tornado event having possible limited impacts across South Texas. Potential impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. * SURGE: Prepare for locally hazardous surge having possible limited impacts across the Middle Texas coast. Potential impacts in this area include: - Localized inundation with storm surge flooding mainly along immediate shorelines and in low-lying spots, or in areas farther inland near where higher surge waters move ashore. - Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road. - Moderate beach erosion. Heavy surf also breaching dunes, mainly in usually vulnerable locations. Strong rip currents. - Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: WATCH/WARNING PHASE - Listen to local officials for recommended preparedness actions, including possible evacuation. If ordered to evacuate, do so immediately. * OTHER PREPAREDNESS INFORMATION: If you are a visitor, be sure to know the name of the city or town in which you are staying and the name of the county or parish in which it resides.
