HLSBRO This product covers The Rio Grande Valley and Deep South Texas ***TROPICAL STORM WATCH NOW IN EFFECT FOR THE LOWER TEXAS COAST*** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - A Tropical Storm Watch has been issued for Cameron Island, Coastal Cameron, Coastal Kenedy, Coastal Willacy, Kenedy Island, and Willacy Island * CURRENT WATCHES AND WARNINGS: - A Tropical Storm Watch is in effect for Cameron Island, Coastal Cameron, Coastal Kenedy, Coastal Willacy, Kenedy Island, and Willacy Island * STORM INFORMATION: - About 470 miles south-southeast of South Padre Island TX or about 510 miles south-southeast of Port Mansfield TX - 20.3N 93.2W - Storm Intensity 40 mph - Movement North-northwest or 345 degrees at 7 mph SITUATION OVERVIEW ------------------ At 400 PM CDT, a very large area of low pressure across the Bay of Campeche is expected to move toward the north-northwest near 7 mph, with this general motion expected to continue through Tuesday. A turn toward the west-northwest is expected Tuesday night or Wednesday, and the system is likely to approach the western Gulf coast late Wednesday as a potential Tropical Depression or Tropical Storm. As a result of this uncertainty and the broad scope of the low, Tropical Storm Watches are now in effect for coastal waters and island to coastal portions of Kenedy, Willacy and Cameron counties for Potential Tropical Cyclone 1. Regardless of tropical development, the main hazards across the lower Texas coast into Deep South Texas remain flooding rainfall of generally 4-8 inches, with localized rainfall amounts up to 10 or more inches, especially towards the coast. Beach and marine conditions will become dangerous as well, with coastal flooding, deadly rip currents, high surf, gusty winds, and low visibility in heavy rainfall. The strongest winds of this tropical system may reside well north of any circulation and extend further. Tropical wind gusts to 40 kts are possible offshore and potentially just into coastal portions of Kenedy, Willacy, and Cameron counties. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Prepare for dangerous rainfall flooding having possible significant impacts across The Rio Grande Valley and Deep South Texas. Potential impacts include: - Moderate rainfall flooding may prompt several evacuations and rescues. - Arroyos and larger creeks may quickly become swollen with swift 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. * SURGE: Prepare for locally hazardous surge having possible limited impacts across the lower 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 exposed parking lots could become covered with some 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 damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. Elsewhere across The Rio Grande Valley and Deep South Texas, little to no impact is anticipated. * WIND: Prepare for hazardous wind having possible limited impacts across the lower Texas coast and coastal portions of Kenedy, Willacy, and Cameron counties. Potential impacts in this area 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. Elsewhere across The Rio Grande Valley and Deep South Texas, little to no impact is anticipated. * TORNADOES: Little to no additional impacts are anticipated at this time across The Rio Grande Valley and Deep South Texas. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials. * OTHER PREPAREDNESS INFORMATION: When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes extend well away from the center of the storm. If you live in a place particularly vulnerable to flooding, such as near the ocean, in a low-lying or poor drainage area, or near an already swollen arroyo, large creek, or the Rio Grande, plan to move to safe shelter on higher ground. Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast. There is a threat from tornadoes with this storm. Have multiple ways to receive Tornado Warnings. Be ready to shelter quickly. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Brownsville TX around 7 PM CDT, or sooner if conditions warrant.

Therefore, the National Hurricane Center has upgraded it to Potential Tropical Cyclone One this afternoon. A Tropical Storm Watch is now in effect along all coastal counties and marine zones from Baffin Bay through Port O'Connor. Regardless of development and eventual landfall location, there are several hazards and impacts expected across South Texas from tonight through Thursday due to the large extent of this system. The main threats will be: - Flash Flooding: Moderate to high threat of flash flooding mainly east of I-37, especially in urban areas Tuesday through Thursday. Rainfall accumulations of 8-10" are expected along the Coastal Bend with localized rainfall amounts up to 15". Across the rest of the region, the Victoria Crossroads could see accumulations of 6-8" through Thursday, while the Brush Country could have amounts as high as 4-6". - Coastal Flooding: Significant coastal flooding is expected with up to 3 ft of inundation possible across the Middle Texas Coast including the bays between Baffin Bay and Matagorda Bay. In addition, there will be a High risk of rip currents. - River Flooding: Considerable river flooding along portions of the eastern Coastal Plains and Victoria Crossroads from Tuesday night through Thursday. There is a 15% chance of Major flooding at Oso Creek. - Winds: Sustained winds of 30-35 mph with gusts to 40-45 mph can be expected across the Coastal Bend, while winds of 30-40 knots can be expected over the marine zones. - Hazardous Seas: Wave heights 12 to 15 feet with occasionally up to 18 feet.
