Officials urged residents in a county southwest of Houston to evacuate on Tuesday due to a levee that breached, adding to the rising floodwaters.
The agency posted a photo on twitter saying "The levee at Columbia Lakes has been breached!! GET OUT NOW!!"

Brazoria County is located southwest of Houston.
Brazoria County Judge Matt Sebesta said residents were warned that the levee would be overtopped at some point, and a mandatory evacuation order was given Sunday.
The levee was later fortified, but officials said they did not know how long the work would hold.
Officials in Houston were also keeping an eye on infrastructure such as bridges, roads and pipelines that are in the path of the floodwaters.
Before it breaks up, Harvey could creep as far east as Mississippi by Thursday, meaning New Orleans, where Hurricane Katrina unleashed its full wrath in 2005, is in Harvey’s path. Foreboding images of Harvey lit up weather radar screens on the 12th anniversary of the day Katrina made landfall in Plaquemines Parish.
The disaster is unfolding on an epic scale, with the nation’s fourth-largest city mostly paralyzed by the storm that arrived as a Category 4 hurricane and then parked over the Gulf Coast. The Houston metro area covers about 10,000 square miles (25,900 square kilometers), an area slightly bigger than New Jersey.
