(CNN) — A spate of unexpected disasters are gripping Texas cities nearly a week after Hurricane Harvey slammed into the coast.
The entire city of Beaumont — population 118,000 — has no running water after both of its water pumps failed. And they won’t be fixed until the floodwater has receded.
In Crosby, plumes of black smoke filled the morning sky after two explosions at a flooded chemical plant.
And in Houston, where authorities will go door-to-door to search for victims Thursday, residents near the Barker Reservoir must flee immediately as the massive pool of water is at imminent risk of overflowing and swallowing their homes.
‘The worst is not yet over’
Across the state, families are searching tirelessly for missing relatives on the sixth day since the catastrophic storm made its first landfall as a Category 4 hurricane.
At least 37 deaths related to Hurricane Harvey and its aftermath have been reported in Texas.
Among the dead are a Houston man who was electrocuted while walking in floodwaters and a mother whose body was floating about a half mile from her car. Rescuers found her daughter clinging to her body. The child is in stable condition after suffering from hypothermia.
“The worst is not yet over for southeast Texas,” Gov. Greg Abbott said Wednesday.
Pleas for help
On Thursday, Federal Emergency Management Agency workers and firefighters will assess the extent of Harvey’s destruction in the southwestern part of Houston, the nation’s fourth largest city.
About 100 miles east, Beaumont residents could find themselves without running water Thursday morning. Local officials said the city’s water pump station has failed and they need to wait until floodwaters recede to make any repairs.
In Port Arthur, desperate pleas of help piled up after residents woke up to rising waters when the storm made its final landfall Wednesday morning.
A shelter in Port Arthur had to be evacuated after the water came inside, and residents such as Julia Chatham remain trapped in their homes.
“All I have in my house is power. I have no food. I have no water. I only have power in my house. I don’t have no way of getting around,” Chatham said. “I’m stuck upstairs. It’s just me and my dog. And I’m upstairs with my other neighbors. It’s like five of us up here.”
In the Houston area, officials said that more than 4,800 people have been rescued by the Coast Guard and local police while countless people are waiting for aid.
Blasts at chemical plant
One deputy was hospitalized after he inhaled fumes from the Arkema peroxide plant in Crosby, the Harris County Sheriff’s Office tweeted. Nine others drove themselves to the hospital as a precaution, the sheriff’s office said.
But the smoke the 10 deputies inhaled is believed to be a nontoxic irritant, the sheriff’s office tweeted.
The explosions were reported around 2 a.m. (3 a.m. ET).
The facility, which is between Houston and Beaumont, had been closely monitored after plant officials said they expected a chemical reaction that will likely cause a fire that will “resemble a large gasoline fire.”
The thick black smoke from the explosions “might be irritating to the eyes, skin and lungs,” Arkema officials said in a statement.
The scope of the explosions is still unknown.
The company shut down the facility as Harvey approached last week and evacuated employees as well as residents within 1.5 miles of plant as a precaution after it was flooded under more than 5 feet of water.
After sitting without power and refrigeration for days, the chemicals at the facility heated up and eventually burned, causing the explosions. It was a matter of time before a fire started, the company had said.
“The high water and lack of power leave us with no way to prevent it,” Rich Rowe, Arkema’s president and CEO, said in a statement.
The company has said there’s a small possibility that the organic peroxide, which is used in the production of plastic resins, will get into floodwaters “but it will not ignite and burn.”
The flooding in southeast Texas has severely affected oil and chemical plants. Many have shut down operations in the past few days, including, the Colonial Pipeline, which carries huge amounts of gasoline and other fuel between Houston and the East Coast. Valero and Motiva, the largest refinery in the country, have also closed some facilities.
Electrocuted man tried to warn off friend
Andrew Pasek was walking through 4 feet of water trying to get to his sister’s house when he accidentally stepped on a live electrical wire.
“He felt the charge and knew something was wrong right away and tried to shake it off right away,” said his mother, Jodell.
The 25-year-old quickly asked a friend to get away from him “because if you do, you know, you will go too,” he told his friend.
Pasek was electrocuted and died. His mother said no one tried to resuscitate him for an hour until the electricity was turned off.
“It could have been anybody,” she said.
