HOUSTON (NewsNation) — Beryl, now a tropical depression, continues to move inland after battering Texas as a Category 1 hurricane.

At least seven U.S. deaths, and 11 in the Caribbean, have been attributed to Beryl, according to the Associated Press. Of these, one is in Louisiana and six are from Texas.

As the storm heads toward the Northeast, flooding, wind and tornadoes threaten parts of the south-central U.S. on Tuesday.

About 2 million people are now without power, and several homes along the Gulf Coast were ripped apart by Beryl’s hurricane winds. Rain completely drowned roads in feet of water.

No power in the scorching heat

A heat advisory is in effect through Wednesday in parts of Texas, with temperatures in the 90s and heat index values up to 105 degrees expected Tuesday. The widespread loss of power — and therefore air conditioning — could make for dangerous conditions, the National Weather Service said.

In Houston, at least 50 people had to be rescued from floodwaters as parts of the city saw more than 10 inches of rain that flooded highways and trapped cars.

“Houstonians need to know we’re working around the clock so you will be safe,” the city’s Mayor John Whitmire said Monday at a media briefing while urging residents to know the dangers of high water, to stay hydrated and to check on their neighbors.

Texas officials said restoring electricity will take days.

Patrick said CenterPoint Energy was bringing in thousands of additional workers to help get the lights turned back on quickly. He said the storm toppled 10 transmission lines and that many of the outages were caused by fallen trees.

Beryl moves northeast

The storm weakened into a tropical depression after making landfall, and by Tuesday morning, its center was over southwestern Arkansas, moving northeast with maximum sustained wind speeds near 30 mph, the weather service said. Its strength isn’t expected to change much in the next day or two.

Beryl still threatens to unleash more harsh weather over several other states in the coming days. It is expected to bring heavy rainfall and possible flash flooding from the lower and mid-Mississippi Valley to the Great Lakes on Tuesday into Wednesday, the weather service said.

A flood watch was in effect for parts of Oklahoma, Arkansas, Missouri, Illinois, Indiana and Michigan, and tornadoes were possible through the early morning across parts of the mid-South. A few tornadoes are possible from midday to the early evening in Missouri, Tennessee, Kentucky, Illinois, Indiana, and Ohio, according to the weather service.

Beryl on Tuesday was far less powerful than the Category 5 behemoth that earlier tore a deadly path of destruction through parts of Mexico and the Caribbean. But its winds and rains still knocked down hundreds of trees that had already been teetering in water-saturated earth and stranded dozens of cars on flooded roads.
