Tropical Storm Harold has weakened to a tropical depression, but officials in Texas are still warning of potential flooding from heavy rain up through Wednesday.

Despite the tropical storm warnings being discontinued late Tuesday, areas were seeing up to six inches of rain, with an average of 2 to 4. Zavala, Maverick, and Dimmit counties were issued a flood advisory as of Tuesday night.

Flooding is expected to be more severe in Mexico, where areas saw 4 to 6 inches of rain on average, with some facing a potential 10 inches through Wednesday.

Much of Texas was experiencing drought prior to Harold, and while the heaviest rain will not reach the driest areas, it is still expected to provide relief from the high temperatures in cities like Austin, Corpus Christi, and Brownsville.

Excessive heat alerts have still been issued in the eastern portion of the state, with more than 70 million people under heat advisories, and 75 million under excessive heat warnings, according to the weather service.

Gov. Greg Abbott deployed state emergency response resources on Monday ahead of the storm's arrival, and activated the Texas State Emergency Operations Center to Level 2, also known as "elevated response conditions."

“Texas stands ready to deploy all available resources to South Texas as tropical storm conditions impact the region this week,” he said. "I encourage Texans to remain weather-aware and heed the guidance of state and local officials and emergency management personnel as they work together to keep communities safe."

Harold is the second tropical storm to impact the United States this week, as Southern California has also undergone intense rainfall and flooding from Tropical Storm Hilary. As of Monday morning, over 7 million people were under a flash flood warning.

As heavy rain is also considered unusual in Southern California during the summer as it is in Texas, the storm has put a strain on the state's land and infrastructure.
