Water started rising on some roadways. Ledbetter Drive at Interstate 35 is closed due to high water and some streets near the Trinity River are flooded.

The Trinity River remains inside its levees in Dallas and already flood control pumps are removing some remaining standing water from low lying areas and sending it to the river.
The city of Dallas said the Trinity can handle more rain over the next two days, but there is still concern upstream. The Army Corps of Engineers may need to release water from Lakes Grapevine and Lewisville.
"We'll be able to move a lot of water. The rain event is not as worrisome as what happens two days after the rain ends and how much water is coming from upstream in dams that are going to be released," said Rocky Vaz, director of Emergency Management.
Lake Worth is closed to all boating activities because boat wakes can cause flooding in some homes and some boat docks are under water.

Gov. Greg Abbott spoke Wednesday morning from the state's operations center. He talked about the impact of Bill and money that's been freed up to help with repairs from previous floods.
"FEMA has done an outstanding job, very quickly giving us, I think, everything requested," he said. "Now we just need to follow through and make sure this assistance gets to individuals as quickly as possible."
