Residents along Wilderness Road in The Woodlands are loading as many of their possessions as they can into U-Hauls and car trunks Friday.
They spent much of the day and night working quickly, before the overflowing creek that claimed the end of their street takes over their homes.
The high water from hours of heavy rains already seeped into several houses close to Spring Creek Friday.
Montgomery County Emergency Management officials said the creek is likely expected to crest at 29 feet by midnight. They warned the flooding could be as damaging as what residents experienced during Tropical Storm Allison in 2001.
"When I see it coming that far up it scares me because it did that before," said Delilah Leverett.
"It's so frustrating because it can happen so fast," said Alena Garcia.
Lorene Radford has lived on Wilderness Road for more than 40 years and watched several homes disappear under flood water in years past.
"We were just hoping and praying you know that it wouldn't be that bad," Radford said.
Red Cross volunteers opened a shelter at Glen Loch Elementary School, a few blocks from the flooding.
However, some resident have decided to stay in their homes. Leverett moved some of her belongings to higher ground, but she said she won't move until her home is submerged in water and rescue crews come for her.
"If I have to go out in a boat, I'll go out in a boat," she said.
