Storm Beryl kills three, knocks out power for 2.7 million in Texas

Beryl, the season's earliest Category 5 hurricane on record, weakened from a hurricane after pounding the coastal Texas town of Matagorda with dangerous storm surges and heavy rain before moving across Houston, the U.S. National Hurricane Center (NHC) said. The agency said conditions could spawn tornadoes in Texas, Louisiana and Arkansas.

The storm, which was expected to rapidly weaken as it moved inland, swept a destructive path through Jamaica, Grenada, and St. Vincent and the Grenadines last week. It killed at least 11 in Mexico and the Caribbean and before reaching Texas, Lieutenant Governor Dan Patrick told reporters.

In Texas, a 53-year-old man and a 74-year-old woman were killed in two incidents by trees that fell on their homes in the Houston area on Monday. A third person, a city of Houston employee going to work, drowned in an underpass, Patrick said.

Oil refining activity slowed and some production sites were evacuated in the state that is the nation's biggest producer of U.S. oil and natural gas.

"For those of you in northeast Texas, be aware. You will have tropical storm winds, maybe as late as midnight or 1 a.m. You will have flooding, you will have rain, and you need to stay off the roads," Patrick said.

State officials had yet to assess the economic damage as officials remained on a rescue footing while powerful winds continued to blow. Restoring power would take several days, said Thomas Gleeson, chair of the Texas Public Utility Commission.

More than 2,500 first responders were deployed statewide, said Nim Kidd, chief of the Texas Division of Emergency Management.

Following warnings that it could be a deadly storm for communities in its path, people rushed to board up windows and stock up on fuel and other essential supplies.

Before daybreak, strong gusts and torrential rain lashed cities and towns such as Galveston, Sargent, Lake Jackson and Freeport, television video showed. By late morning, many fallen trees blocked roads in Houston as the worst of the storm passed, with persisting winds and some road flooding, rendering lanes on major freeways impassable. The city barricaded flooded areas.

Crews using a life jacket and ladder fire truck rescued a man from a truck on a flooded stretch of freeway, video posted on social media by Houston's local ABC station showed. Patrick said there were several other rescues.

Flood waters exceeded 10 inches (25 cm) across most of Houston, Mayor John Whitmire said.

"We're literally getting calls across Houston right now asking for first responders to come rescue individuals in desperate life safety conditions," Whitmire said.

The storm had strengthened to a Category 1 hurricane as it crossed the warm waters of the Gulf of Mexico before making landfall. But the NHC said it was expected to weaken into a tropical depression overnight and a post-tropical cyclone on Tuesday.

That was still enough to deliver more heavy rain as it moved northeastward from eastern Texas on Monday afternoon, across Arkansas on Tuesday, into the Lower Ohio Valley on Tuesday

night, and finally into the Lower Great Lakes on Wednesday, the U.S. National Weather Service said.

The Federal Emergency Management Agency (FEMA) and the U.S. Coast Guard had positioned staff to assist with search and rescue efforts. FEMA also readied water, meals and generators to boost local response efforts, according to the Biden administration.

Schools said they would close as the storm approached. Airlines canceled more than 1,300 flights, and officials ordered a smattering of evacuations in beach towns. Small businesses in Houston, including package delivery services and chiropractors, delayed openings or were closed on Monday.

More than 2.7 million homes and businesses in Texas lost power, according to Patrick and and PowerOutage.us.

Several counties in southeastern Texas - including Houston, where many U.S. energy companies are headquartered - are under a flash-flood warning as thunderstorms unleashed up to nearly 12 inches (30 cm) of rain in some areas.

Closures of major oil-shipping ports around Corpus Christi, Galveston and Houston ahead of the storm could disrupt crude oil exports, along with shipments of crude to refineries and motor fuel from the plants. The Corpus Christi Ship Channel has re-opened, while the Port of Houston was projected to resume operations on Tuesday afternoon.

Some oil producers, including Shell and Chevron, evacuated personnel from their Gulf of Mexico offshore production platforms ahead of the storm.

Marathon Petroleum Corp's refinery in Texas City, Texas was hit by a power interruption on Monday amid the storm, the company said in a statement.
