Beryl made landfall in Texas early Monday morning as a Category 1 hurricane, killing at least two people in the state.

Nine more people died last week as the storm moved across the Caribbean and Mexico's Yucatan Peninsula.

Since making landfall in Texas, Beryl has weakened and is now classified as a tropical storm. However, officials are warning of continued rain and dangerous flash flooding as they move into Texas.

Here's what you need to know:

Tornado Deaths in Texas: A 53-year-old Houston-area man died when a tree fell on his home in Harris County, according to Sheriff Ed Gonzalez. A 74-year-old woman also died when a tree fell through the roof of her home, district officials said.

Power outages and other impacts: According to Poweroutages.us, more than 2 million customers are without power across Texas. In Houston, some services have been suspended: public transportation has been suspended until further notice and several hospitals have canceled elective surgeries. Houston's George Bush Intercontinental and William B. Flight tracking website Flightware reports that most flights have been canceled at hobby airports.

Storm surge: The Gulf of Mexico advanced over Texas, driven by Beryl's winds. A surge of about 1.6 meters affected the northern end of Galveston Bay near Morgan Point, and about 1.2 meters elsewhere. Storm surge reached 1.4 meters on the western side of the bay near Eagle Point.

General warnings: More than 3.5 million people in Texas, Louisiana and Arkansas are under a tornado watch as of 10 p.m. Central Time, according to the Storm Prediction Center.

Climate crisis: Ocean waters around the world have been warm for more than a year — often at record levels. Water in Beryl's track helped the storm rapidly intensify as it moved across the Caribbean. ClimaMeter analyzes have revealed that the impact of Cyclone Beryl on Jamaica has been exacerbated by climate change.
