The National Weather Service released a terrifying statement Sunday on the situation in southeastern Texas, calling the wreckage of Hurricane Harvey "unprecedented" and "beyond anything experienced."
Per the Associated Press, the Houston Fire Department said that it has responded to more than 2,5000 emergency calls as of midday Sunday. Another 1,000 calls were still awaiting aide.
Residents of Houston are being advised to take to their roofs in order to avoid flooding. Officials have asked residents to not leave their homes. There are reportedly no safe exit routes in Houston.
The National Weather Service said that total rainfall could reach as high as 50 inches. Houston's average annual precipitation usually measures 49.8 inches, according to the National Centers for Environmental Information.
The U.S. Coast Guard has responded to the disaster, deploying helicopters from all over the country to assist aide.
To make matters worse for the people of southeast Texas and Louisiana, the National Weather Service issued a tornado watch Sunday.
