(CNN)Flash flood watches are affecting nearly 11 million people along the coasts of Texas and Louisiana as Beta, now downgraded to a tropical depression, moves slowly inland, dumping more rain on an already saturated region.
Beta downgraded from tropical storm as it dumps more rain on already soaked Texas
Beta moved inland from the Gulf of Mexico, producing heavy pockets of rain over parts of Houston. The storm has already dropped up to a foot of rain in some areas with more on the way Wednesday.
The storm was producing 30 mph sustained winds, according to the National Hurricane Center, and was centered around 60 miles from Victoria, Texas, as of late Tuesday night.
It is not Beta's slow speed that is producing widespread rain, but pockets of heavy rainfall -- which are leading to flash flood conditions as it stalls over Texas. It's not expected to move out of the area until Wednesday night.
A group of volunteers in Houston used kayaks to rescue those stranded from the flooding, CNN affiliate KPRC reported.
In Jamaica Beach, Texas, Ann Williams was driving to check her rental property when she was met by severely flooded streets due to Beta's storm surge.
"We have seen the water high before with storms, but not like this," she told CNN. "So it was a little scary driving down the street to get to the house."
The water levels were also high at her rental home, rising over the docks in the back of her property. Williams says the water levels have since receded somewhat and believes the worst is over.
A family in southwest Houston near Keegans Bayou was seen leaving a nearby restaurant, wading through the water to higher ground after a waiter had warned them that the flood waters were rising, according to CNN affiliate KTRK.
Many businesses closed, leaving employees whose cars were unreachable to ask loved ones to come pick them up.
The storm is expected to pick up speed and should be out of Texas on Wednesday night and into Louisiana, and then Mississippi through Friday.
Louisiana Gov. John Bel Edwards said the state is still anticipating continued impacts from Beta even after the storm was downgraded.
Coastal flooding continues to be a concern at least through Thursday, Edwards said. Grand Isle is engaged in an active flood fight and many communities outside of the major flood protection systems are experiencing some levels of flooding, the governor added.
"We're keeping a close eye on those areas and will deploy flood-fighting assets, should the need arise," he said.
Edwards said there were just over 11,000 individuals still sheltering across the state after Hurricane Laura last month, with more than 4,000 Louisiana residents still sheltering in Texas.
