Hurricane Beryl made landfall in Texas early Monday, resulting in two reported deaths and causing torrential flooding, power outages, structural damage, and travel headaches for thousands.

The Category 1 hurricane landed in Matagorda around 4 a.m. with maximum sustained winds of 80 mph, according to the National Weather Service (NWS) in Brownsville.

NWS issued life-threatening flash flood warnings for multiple areas as heavy rainfall battered areas along the Texas Gulf Coast. A reported 4-6 inches of rain has fallen in Angleton and Pearland. Significant flooding has been reported along major and minor roadways, according to Click 2 Houston.

More than 2 million are without power as of 10:45 a.m., per Poweroutage.us, with the most outages logged in Galveston, Jefferson, and Montgomery counties.

The storm has snarled air traffic, causing 986 flight cancelations and 35 delays at George Bush Intercontinental Airport in Houston. William P. Hobby Airport has reported 308 cancelations and 20 delays, according to Flight Aware.

One person has been confirmed dead in Humble, about 20 miles north of Houston, after a tree fell on a house, Harris County Sheriff Ed Gonzalez shared on social media.

“The man (53) was reportedly sitting in [the] house with family, riding out the storm. An oak tree fell on [the] roof and hit [the] rafters; [the] structure fell on the male. Wife and children unharmed,” Gonzalez wrote in the social media post.

Another person was confirmed dead in Houston, according to Mark Herman, Harris County Constable of Precinct 2.

“The caller advised a tree fell through the roof of her grandmother’s room. We are saddened to report that the 74-year-old victim has been confirmed deceased. Please keep her family in your prayers. Constable Deputies are continuing the investigation on scene,” Herman posted on social media.

As of 10 a.m., the hurricane was downgraded to a tropical storm after winds dropped to 70 mph, per NBC5 DFW. The storm will likely weaken to a tropical depression as it continues moving northward over land areas.
