Heavy rains from Beta have shifted away from the Houston area after causing extensive flooding, but the storm on Tuesday is threatening to cause more damage in parts of Louisiana still recovering from Hurricane Laura.
The National Weather Service (NWS) said that over 11 million Americans are under flash flood watches, as the storm could bring up to 15 inches of rain along the Texas coast and up to 5 inches of rain inland.
"Significant urban flooding will continue as well as minor to isolated moderate river flooding," the National Hurricane Center (NHC) said Wednesday morning. "Flash flooding will remain possible through Wednesday afternoon."
In the nation's fourth-largest city, Beta caused extensive flooding on streets and freeways on Tuesday.
Forecasters said Beta brought new daily rainfall records to the city of Houston, which saw 3.58 inches and Houston-Hobby Airport, which saw over 7 inches of rain.
The Texas Department of Transportation said Tuesday night that 37 different locations were being impacted by high water. Water levels were beginning to recede in some locations by Wednesday morning.
Houston Fire Chief Samuel Peña said first responders had done nearly 100 water rescues on city roadways since Monday evening.
Harris County Judge Lina Hidalgo said there were preliminary reports of some home flooding along a creek south of Houston.
Both Hidalgo, the top elected official in Harris County, and Houston Mayor Sylvester Turner urged residents to stay home and off the roads. About 70 barricades had been placed throughout the city in high water areas.
“Your sedan is not a submarine. Your minivan is not magical. So stay off the roads right now," Hidalgo said. “Your destination is not worth your life. It's not worth the life of the first responder that’s going to have to come and rescue you if you drive into high water and are stuck there."
In Friendswood, Texas, south of Houston, officials warned residents in the 100-year flood plain to be prepared to evacuate the area if necessary after the Clear Creek rose 2 to 4 feet past its banks.
“I’m nervous. I don’t want my house to flood. It never flooded and it didn’t flood during Harvey but you never know," Rosemary Kacsmarski told FOX26. "You never know where the rain is going to fall the hardest and who’s going to get hit this time."
Water levels were still rising on Wednesday morning in some neighborhoods.
City officials in Houston also said that more than 100,000 gallons of domestic wastewater spilled in five locations due to "intense, sustained, rainfall of greater than 10 inches in the last 24 hours."
Officials told FOX26 that as of late Tuesday, the estimated volume of released wastewater at each of the locations is greater than 100,000 gallons.
The city said the water supply is unaffected, and a boil notice is not necessary
The Houston Police Department said a fisherman was reported missing in Brays Bayou after someone reported he "jumped into the water" just after 6 p.m.
HPD Commander Elizabeth Lorenzana told KTRK-TV it was unknown if the man jumped into the water or if he lost his footing and fell in.
"It's very dangerous to go out into the bayou," Lorenzana said. "I recommend people not going to the bayou."
The man's body was recovered just before 10:30 p.m., KTRK reported.
Beta was the ninth named storm that made landfall in the continental U.S. this year. That tied a record set in 1916, according to Colorado State University hurricane researcher Phil Klotzbach.
Beta was expected to move over Louisiana, Arkansas, and Mississippi later in the week, bringing the risk of flash flooding. Storm surge flooding from Beta was impacting coastal Louisiana on Tuesday.
The rainfall and storm surge prompted Louisiana Gov. John Bel Edwards to declare a state of emergency.
The storm was already having impacts in Cameron Parish, where residents are still working to clean up the damage from Hurricane Laura.
"We definitely have some flooding in the low-lying southern parts of the parish," Sheriff Ron Johnson told the Daily Advertiser. "No houses or structures have flooded, but some roads are impassable. It’s affecting us as to how we get where."
Johnson advised people with campers to evacuate and many did. The sheriff added that there weren't that many people to evacuate overall due to many having lost their homes in Laura.
