"Any hurricane is an enormous challenge," Gov. Greg Abbott said in a news conference Saturday. "This challenge is complicated and made even more severe, seeing that it is sweeping through an area that is the most challenged area in the state for Covid-19."
Hanna made landfall Saturday evening on Padre Island, south of Corpus Christi, according to the National Hurricane Center. It's the first hurricane of the season in the Atlantic and had sustained winds of 90 mph, making it a high-end Category 1 hurricane.
Early Sunday morning, it was downgraded to a tropical storm as it moved westward through southern Texas into northeast Mexico, according to the National Weather Service in Brownsville.
As of 2 pm EDT, the tropical storm had maximum sustained winds of 40 mph and was expected to weaken into a tropical depression later Sunday as it moved into northeast Mexico, the National Hurricane Center said.
Widespread rainfall totals are between 4-6 inches, but some places have seen a foot of rainfall. There is still the chance for 2-4 inches of rain in parts of southern Texas as well as the chance of isolated tornadoes through the rest of Sunday.
In Corpus Christie, part of a popular pier collapsed, CNN affiliate KRIS reported, and high waters encroached on the Art Museum of South Texas.
Abbott issued a disaster declaration for 32 counties in the state and has also issued a federal emergency disaster declaration request. Urging extreme caution, Abbott warned residents across the state not to forget about the virus because of the storm.
FEMA approved a Federal Emergency Declaration following the storm's landfall, Gov. Abbott's office said in a press release on Sunday.
Officials in Hidalgo County, where several of the affected cities are located, reported overwhelmed hospitals last week filled to capacity and a judge ordered residents to shelter at home following upticks in both coronavirus cases and hospitalizations.
"This is a time in response to a hurricane where sometimes people will come together, come together to shelter, come together just as close family come together, as friends come together to respond," Abbott said. "That coming together will continue to provide the ability for Covid-19 to transmit from one person to another."
'Life-threatening' flooding expected, governor says
Some of the southernmost parts of Texas received over a foot of rain as the center of the storm crossed over to northeastern Mexico, CNN meteorologist Derek Van Dam said.
Areas across southern Texas were expecting another five to 10 inches of rain through the early morning, with some localized spots seeing as much as 18 inches of water. Areas along the Rio Grande Valley are especially susceptible to flooding, Van Dam said. Expected flooding in the Rio Grande Valley could be "life-threatening," the governor said Saturday evening, as Hanna was making landfall.
"The storm will basically rain itself out over extreme southern Texas and northeastern Mexico," he said.
Flash flood warnings are in effect by the weather service for areas including the city of McAllen, Mission, Brownsville, San Benito, Donna, Mercedes, Raymondville and Lyford.
"We'll continue to see dramatic waves of flooding including flash flooding that will come upon people suddenly. One moment they will be in an area ... where it seems like there's a little rain and then moments later, they could be awashed in water up to their doors, if they're in their cars, up to their knees, if they're walking around," the governor said Saturday.
Meanwhile, another potential tropical system that could develop over the next five days is trekking behind Hanna across the Atlantic Ocean, Van Dam said.
Over 250,000 without power
Tropical storm-force winds in parts of Texas could cause power outages and damage to buildings and trees, the weather service said. There is the possibility of brief spin-up tornadoes, Van Dam said, and there will still be dangerous rip currents and localized beach flooding along the coast.
Over 250,000 customers in south Texas are without power following Hurricane Hanna's landfall on Saturday afternoon, according to power companies. Over 173,000 customers are without power in Hidalgo County alone, according to local power companies.
In Mission, Texas, officials said early Sunday morning emergency responders had already been dispatched to several homes for water rescues. A tornado warning was issued running through early Sunday morning and officials reported thousands of residents were left without power, after heavy winds caused damage to power lines and traffic signals.
"Electricity crews must shelter in place due to wind speeds & the rain," the City of Mission said on Twitter. "You're asked to only report downed power lines or safety hazards. Crews will continue to respond to outages when it's safe to do so."
