South Texas is bracing for heavy rain, flooding, powerful winds and dangerous rip currents as a tropical depression churning in the Gulf of Mexico is forecast to strengthen and hit the state Tuesday as a tropical storm.
Tropical Depression 9 was stirring up maximum sustained winds of 35 mph and “moving fairly quickly” at 18 mph around 11 p.m. ET Monday, when it was about 260 miles from Port Mansfield, Texas, according to the National Hurricane Center.
It was expected to move inland over south Texas by midday Tuesday, the hurricane center said. The latest track has the system making landfall south of Corpus Christi.
The tropical depression, which formed in the Gulf of Mexico late Monday afternoon, is expected to dump of 3 to 5 inches of rain – and up to 7 inches in some areas – across South Texas on Tuesday and Wednesday.
Tropical storm conditions are expected, with winds of 40 to 50 mph lashing the region and rising waters moving inland from the shoreline and bringing floods, forecasters said.
“The deepest water will occur along the immediate coast near and to the north of the landfall location, where the surge will be accompanied by large waves,” the hurricane center said.
South Beach and North Beach were closed for driving and camping Monday in anticipation of the storm’s arrival, Padre Island National Seashore officials said, warning of storm surge of 1-3 feet. The national seashore is located along a barrier island south of Corpus Christi.
Tropical storm warnings have been issued from the mouth of the Rio Grande to Port O’ Connor, Texas, with tropical storm watches in effect from Port O’Connor to Sargent, Texas.
Texas Gov. Greg Abbott deployed the Texas National Guard, swift water rescue boat squads, among other emergency resources ahead of the storm’s arrival. “Texas stands ready to deploy all available resources to South Texas as tropical storm conditions impact the region this week,” he said in a statement.
“I encourage Texans to remain weather-aware and heed the guidance of state and local officials and emergency management personnel as they work together to keep communities safe,” the governor added.
Corpus Christi officials told residents who must be outside during the incoming storm to drive slower than usual, turn on their headlights and be aware of possible flooding in low-lying areas.
Crews across the Corpus Christi area could be seen working Monday to prep critical canals and drainage infrastructure for the heavy rainfall.
About 40 miles northeast, the city of Port Aransas has declared a local state disaster on Monday ahead of impacts from Tropical Depression Nine.
The city is “under the threat of imminent disaster, injury, or loss of life or property, resulting from a Tropical Storm, which will impact the coastal beaches of the City of Port Aransas Nueces County, Texas with flooding or severe damage,” the proclamation said.
Naval Air Station Kingsville ordered those in the RV Park on the installation to evacuate, while voluntary evacuations were called in Riviera, Baffin Bay and Loyola Beach, authorities said.
Meanwhile, AEP Texas, which delivers power to South Texas, said it is lining up crews, equipment and other resources in anticipation of possible power outages.
The potential tropical storm is moving toward southern Texas comes as the region – including Corpus Christi – battles its hottest, and one of the driest, summers on record.
While this tropical system’s rains could help quench parts of the drought-stricken state, some of the worst drought conditions – areas of extreme and exceptional drought in Central Texas – might miss out on much of the rain.
The system headed to Texas is the latest sign the Atlantic hurricane season is ramping up. Three tropical systems formed in 24 hours Saturday into Sunday, and the Texas storm marks the fourth.
On Sunday, Tropical Storm Hilary made landfall in Mexico before crossing into California, knocking out power, turning streets into raging rivers and forcing evacuations and water rescues.
Conditions in the Gulf of Mexico are ripe for tropical development. Sea surface temperatures in the Gulf of Mexico are warmer than they’ve ever been on record, according to analysis of NOAA data by hurricane expert Michael Lowry.
Two tropical storms are lined up in the Atlantic Basin, including Tropical Storm Franklin, which is set to impact Hispaniola by mid-week.
Franklin’s center had sustained winds of 50 mph as of 11 p.m. ET Monday, located over the Caribbean about 275 miles south of Santo Domingo, Dominican Republic. It is expected to make a hard turn to the north by Tuesday morning and make landfall in Hispaniola Wednesday.
