Texas flooding updates: Hidalgo warns it's now too late to evacuate East Fork of San Jacinto River; rescues underway

HOUSTON — Water levels are expected to keep rising on Friday as severe thunderstorms continue to bring heavy rain to parts of Southeast Texas.

Disaster declarations have already been signed in Harris County and further north in Huntsville. Those went into effect immediately after being issued Thursday. These allow for more resources to be deployed.

“This threat is ongoing and it’s going to get worse. It is not your typical river flood,” Harris County Judge Lina Hidalgo said Friday.

The city of Houston opened its joint information center Friday morning. Also, the state is sending extra high-water vehicles to help.

The storms are expected to continue to still have an impact this weekend with more storms in the forecast.

Just before 3 p.m. Friday, Harris County Judge Lina Hidalgo said it’s now too late for residents near the San Jacinto River who ignored mandatory evacuation orders to leave. 

“On the San Jacinto River East Fork, it’s too late to evacuate preemptively & folks are being assisted off their rooftops,” Hidalgo posted on X. “If you are on the West Fork or south of Lake Houston you still have an opportunity to leave. Otherwise, prepare to stay in place for 2-3 days.”

The Harris County Clerk’s Office (HCCO) is prepared to conduct the May 4 Uniform and Special Elections on Election Day, Saturday, May 4, in spite of severe weather concerns. 

Although Harris County has received several inches of rainfall over the past few days, no voting locations had been impacted by heavy rain or flooding as of 1 p.m. Friday, May 3.

All 151 voting locations will open as planned from 7 a.m. to 7 p.m. Saturday, Harris Votes said.

HCCO continues to monitor local weather conditions, including the possibility of heavy rain and flooding. The Elections Department staff is in contact with the facilities serving as vote centers to ensure buildings will open, election workers will remain safe and voters will be able to cast their ballot on Election Day.

The Texas Election Code does not provide specific procedures for emergency weather conditions. However, in the event that a voting location is forced to close at any point on Election Day, HCCO will make every effort to advise voters of changes. Information will be shared on www.HarrisVotes.com and social media.

The special election is the race to fill Mayor John Whitmire’s former Senate seat in the Texas Legislature.

Emergency officials expect the San Jacinto River to rise to 78 feet above sea level, which means there will be significant flooding.

“That is just three feet below where it was during (Hurricane) Harvey. So, we will go 78 feet higher than we were the other day, which means even elevated structures will get water. It also means street side structures will have rooftop flooding,” Hidalgo said Thursday in a press conference.

Officials said the river will likely crest this weekend. That is why mandatory evacuations have been issued.

“Even elevated structures will get water. It also means street-side structures will have rooftop flooding. It means the water will be hitting power lines,” Hidalgo said.

These are the neighborhoods included in the evacuation order.

• Idle Glen
• Idle Wild
• Northwood Country Estates
• River Terrace
• Cypress Point
• Commons of Lake Houston

Voluntary evacuation advisories for several other communities around the San Jacinto River. People in the following areas should leave or plan to be stuck for two or three days.

• Kingwood near the west fork of the river
• Forest Cove
• North Shore
• Bellawood
• River Crest
• Rio Villa
• Kingspoint
• Atascocita Shores

Flooding from heavy rains has led to the closure of several major roadways in Southeast Texas. The Texas Department of Transportation in Lufkin closed US 59 from Shepherd to Splendora due to major flooding in the Cleveland area.

Drivers can detour from State Highway 150 to New Waverly to Interstate 45. 

Loop 336 in Conroe is also impassible. FM 2920 around the Grand Parkway in the Tomball area is also closed.

In Montgomery County, officials issued a voluntary evacuation order and said roads were closed because of flooding along the river. The area got about 5 to 8 inches of rain within 24 hours, with some spots getting as much as 10 to 12 inches of rain, said National Weather Service meteorologist Hayley Adams.

“We are still having to rescue motorists who ignore barricades or water over roadways and place themselves and first responders in harms way,” Montgomery County Judge Mark Keough said Friday in a Facebook post.

A family in McDade Estates in Conroe sent us photos of water inside their home. McDade Estates is a subdivision along the east side of the San Jac W Fork along FM 2854.

Shelters are now open and available for any residents who need to evacuate because of flooding concerns. Pets are welcome at both locations.

The storm brought down trees and left vehicles stranded. It prompted the San Jacinto River Authority to close Lake Conroe and increase water releases from the dam that created the reservoir.

The San Jacinto River Authority said Friday morning that with a reduction in inflows into Lake Conroe and reduced rain overnight, dam operators have lowered the release from Lake Conroe to 48,528 CFS. The lake level is currently 204.3 feet. There will continue to monitor rain and runoff in the area throughout the day. 

Harris County Judge Lina Hidalgo said in a press conference Friday morning she spoke with Polk County Judge Sydney Murphy who told her that more than 700 homes had been flooded. She explained that while people there were prepared to be stuck in their homes for a few days, they were not prepared to be without water.

The city of Huntsville issued a Declaration of Disaster on Thursday morning for severe weather, flooding, damaging winds, down trees, and power outages.

Entergy Texas said recent storms caused significant flooding and damage to some of their transmission lines in the Huntsville area. They added that crews have restored power to 70% of their customers impacted by the storms.

Huntsville ISD canceled classes for both Thursday and Friday. 

Here is their full statement posted Thursday:

“After careful consideration and consultation with local emergency management officials, HISD will continue closure through Friday, May 3. Dangerous road conditions are expected to continue into tomorrow, with more rain likely overnight and many roads outside of town still flooded as of 5:30 PM today. Additionally, our creeks, tributaries and rivers are still rising within our boundaries. While we like to wait as long as possible to make this decision so it can be based on real time information, we also realize the more notice we give families and staff, the better it is for their planning. We fully expect to be back to normal operations by Monday, and any changes or updates will be sent through our mass notification system, posted on the district website (www.huntsville-isd.org) and our official social media pages, and will be communicated to media outlets. Our thoughts and prayers are with those who have suffered loss or damage during this weather event.”

Sam Houston State University in Huntsville and Woodlands Center were closed on Thursday and Friday.

The Texas Parks and Wildlife Department has seen impacts to multiple sites due to the recent, extended rain and flooding experienced by parts of the state.

TPWD officials said state parks such as Huntsville, Village Creek and Fort Parker have closed. Once floodwaters recede, park areas will remain closed until repairs and cleanup have finished and areas are safe for public use.

Here is a complete list of parks that are closed.
