HLSBRO This product covers The Rio Grande Valley and Deep South Texas ***TROPICAL STORM WARNING NOW IN EFFECT*** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Tropical Storm Warning is in effect for Cameron Island, Coastal Cameron, Coastal Kenedy, Coastal Willacy, Kenedy Island, and Willacy Island * STORM INFORMATION: - About 410 miles southeast of Brownsville TX or about 440 miles southeast of Port Mansfield TX - 21.8N 92.7W - Storm Intensity 40 mph - Movement North or 5 degrees at 7 mph SITUATION OVERVIEW ------------------ At 10 AM CDT, a large area of low pressure across the Bay of Campeche is moving north at 6 mph, and expected turn toward the west-northwest later today or tonight. This system is expected to continue to slowly strengthen and approach the central Mexico Gulf coast late tomorrow as a Tropical Storm. Tropical Storm Warnings are now in effect for coastal waters and island to coastal portions of Kenedy, Willacy and Cameron counties for Potential Tropical Cyclone One. The main hazard across the lower Texas coast into Deep South Texas remains 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 of up to 3 feet possible, 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 up to 45 mph are likely offshore and potentially into coastal portions of Kenedy, Willacy, and Cameron counties. Higher winds gusts are also possible inland with bands of showers and thunderstorms. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Protect against life-threatening rainfall flooding having possible extensive impacts across The Rio Grande Valley and Deep South Texas. Potential impacts include: - Major rainfall flooding may prompt many evacuations and rescues. - Small streams, creeks, canals, arroyos, and ditches may become dangerous rivers. Flood control systems and barriers may become stressed. - Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become filled with several feet of water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out. Protect against dangerous rainfall flooding having possible significant impacts across Deep South Texas. * WIND: Protect against hazardous wind having possible limited impacts across 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. * SURGE: Protect against locally hazardous surge having possible limited impacts across 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. * TORNADOES: Protect against a tornado event having possible limited impacts across The Rio Grande Valley and Deep 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. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * OTHER PREPAREDNESS INFORMATION: Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding. 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 in which it resides. Listen for these locations in local news updates. Pay attention for instructions from local authorities. Storm surge is the leading killer associated with tropical storms and hurricanes! Make sure you are in a safe area away from the surge zone. Even if you are not in a surge-prone area, you could find yourself cutoff by flood waters during and after the storm. Heed evacuation orders issued by the local authorities. Rapidly rising flood waters are deadly. If you are in a flood-prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, turn around don't drown! If a Tornado Warning is issued for your area, be ready to shelter quickly, preferably away from windows and in an interior room not prone to flooding. If driving, scan the roadside for quick shelter options. Closely monitor weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings. * 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 4 PM CDT, or sooner if conditions warrant.
