Texas Governor Greg Abbott declared states of disaster in 18 counties on Oct.16 after hard rain saturated the soil of central Texas, causing rivers to flood and lakes to spill over their dams.
Much of central Texas is arid plains and rolling hills. Four to eight inches of rain is all the region might expect to see in the entire month of October. Yet more than 10 inches of rain have fallen on the region in a period of just 36 hours.
The resulting flash floods washed out bridges and roads, stranded people in their homes and in some cases washed them away in their cars as they tried to drive to safety.
And now, according to AccuWeather, more moisture is on the way.
Moist air coming ashore off the Gulf of Mexico will bring more precipitation along a corridor stretching from Corpus Christie on the coast and across the state, hitting San Antonio, Abilene, and the Dallas-Fort Worth area.
“The AccuWeather Local StormMax™ for portions of central Texas is projected to be 14 inches from Friday, Oct. 12 through Friday, Oct. 19,” Sosnowski said.
With all the rain that has fallen already on the state, every additional drop just adds to the risk of more flash floods and dam overflows.
Record Rainfall
Flooding of the Llano River reached near-record levels the morning of Oct. 16. The force of the floods was sufficient to knock down the FM 2900 bridge near Kingsland.The Trinity River at Liberty, Texas, is projected to peak at major flood stage this weekend, possibly just a couple feet shy of the record crest of 32.7 feet, AccuWeather reported.
Lake Buchanan and Lake Travis both neared flood levels on Oct. 16.
For meteorologists, autumn lasts from Sept. 1–Nov. 30. By the middle of October, the Dallas area had already passed the previous record of 21.82 inches of rainfall, set in 2015. And of course, more rain is predicted.
The Future Looks Wetter
“There is the potential for another round of heavy rain during the middle of next week,” AccuWeather meteorologist Sosnowski said.There is a tropical storm forming to the west of Texas in the Pacific, which could gather strength and move east ward across the state in the early days of next week—in other words, just about the time people have come out of their storm shelters to appraise the damage done by this weekend’s storms.
AccuWeather holds out some hope. The Pacific storm will have to cross the mountains of Mexico to reach Texas, and may lose some of its moisture in the process.
