The powerful eye wall of Harvey initially reached land by 11 p.m. ET between Port Aransas and Port O'Connor, Texas, with the then-Category 4 storm packing winds of more than 130 mph. Harvey was downgraded to a still-dangerous Category 2 hurricane around 4 a.m. ET when winds dropped to 110 mph, the National Hurricane Center said.
It was the first Category 4 hurricane to make landfall in the United States since Hurricane Charley in 2004.
Millions of residents along the south Texas coast saw hurricane-force winds that knocked down trees, power poles, and signs.
First responders are yet to assess the impact that the extremely powerful hurricane has caused over Texas in the first hours of landfall but forecasters have said it will be devastating and leave areas "uninhabitable for weeks or months."
Harvey has the "highest potential to kill the most amount of people and cause the most amount of damage," said Brock Long, director of the Federal Emergency Management Agency.
As Harvey deluges Texas, coastal cities could see 13 feet of storm surge and as much as 40 inches of rain by Wednesday.
