After Hurricane Beryl slammed into Texas early Monday, knocking out power to nearly 3 million homes and businesses, unleashing heavy rain and killing at least three people it moved east and later weakened to a tropical depression, the National Hurricane Center said Monday evening. The fast-moving tempest threatened to carve a harsh path over several more states in coming days.

Texas state and local officials warned it could take several days to restore power after Beryl came ashore as a Category 1 hurricane and toppled 10 transmission lines and knocked down trees that took down power lines.

Beryl later weakened into a tropical storm and then a tropical depression, far less powerful than the Category 5 behemoth that tore a deadly path of destruction through parts of Mexico and the Caribbean last weekend. But the winds and rains of the fast-moving storm were still powerful enough to knock down hundreds of trees that had already been teetering in water-saturated earth, and strand dozens of cars on flooded roadways.

As it moved inland, the storm threatened to spawn tornadoes and the National Weather Service confirmed on social media that tornadoes had been spotted in northeastern Louisiana. Bossier Sheriff Julian Whittington said in a Facebook post that a woman was killed in the Benton area when a tree fell on her home.

“We’re not past any difficult conditions,” said Texas Lt. Gov. Dan Patrick, who is acting governor while Gov. Greg Abbott is out of the country, warning it would be a ”multiple day process to get power restored.”

Houston took a hard hit as CenterPoint Energy reported more than 2 million homes and businesses without power in and around the nation’s fourth-largest city. Patrick said the company was bringing in thousands of additional workers to restore power, with top priority for places such as nursing homes and assisted living centers.

At least two people were killed when trees fell on homes, and the National Hurricane Center said damaging winds and flash flooding would continue as Beryl pushes inland. A third person, a civilian employee of the Houston Police Department, was killed when he was trapped in flood waters under a highway overpass, Houston Mayor John Whitmire said. There were no immediate reports of widespread structural damage, however.
