HOUSTON — The math is simple, but the potential weather consequences are daunting.
Up to 20 inches of rain have fallen over parts of Texas over the last
few days, breaking some local rain records. In southeast Texas, another
6 to 12 inches were on their way overnight — even more in isolated
spots.
Rain should continue through part of the week.
Add coastal high winds that are driving in high waters on Sunday, and
it all equals flood warnings of almost every type from the National
Weather Service from Corpus Christi up the Gulf Coast to Morgan City,
Louisiana:
— Rivers and creeks were predicted to overflow in Corpus Christi, in
Waco and near San Antonio, Texas, and in Lake Charles, Louisiana.
— Flash flooding in Houston led to 50 confirmed high water locations,
emergency management spokesman Michael Walter said. All exits to
downtown on I-45 were closed.
— Coastal flooding was predicted to push inland from Beaumont east throughout much of the Louisiana coast.
Galveston County is predicted to become inundated on two fronts — up
to a foot of rain is in the forecast, and at the same time tides pushed
by howling winds are projected to rise up to five feet above normal.
Residents of Bolivar Peninsula are advised to evacuate, an official
said.
Wayward streams
In and around Houston, high water led to nearly a dozen road closings late Saturday, CNN affiliate KTRK reported.
When rushing water meets cars and people, danger often results. It
only takes 12 inches of flowing water to sweep away a small car, the
weather service has warned.
“Most flood deaths occur in automobiles. Never drive your vehicle into areas where the water covers the roadway,” it said.
Earlier in the day, flooding washed away cars, and derailed a freight
train. Rescuers pulled motorists out of cars stuck in high water.
One person disappeared in San Antonio, a homeless man who tried to
rescue his dog from a drainage ditch. He was swept away in pre-dawn
hours, a fire official said.
The dog was later found safe. The man hasn’t been.
Records broken
San Antonio broke its all-time single-day rain record Saturday, as did Camp Mabry, a military installation in Austin.
Dallas was in the thick of it Saturday, getting about eight inches of
rain in 24 hours. As the Trinity River approached flood stage, a flood
gate on nearby White Rock Lake opened to release water and keep it from
overflowing.
On roadways in and around Austin, heavy rain prompted the closures of
66 low-water crossings. The city government, via Twitter, urged people
to stay inside.
Rain on top of rain
Though much of the rain has shifted southeast since Saturday,
previously inundated places will get hosed again. Navarro County saw a
jaw-dropping 20-plus inches fall in the last two days. Heavy rain fell
there again overnight, the weather service said.
Navarro is where the train, which was pulling dozens of cars, derailed in high water.
Two workers climbed out then swam to high ground, Union Pacific spokesman Jeff DeGraff told CNN.
“They are in good condition, no injuries, just a little wet and shaken up,” he said.
Patricia’s remnants
The torrents are coming from two weather systems. The first has
hovered over Texas and neighboring states for the last few days, but it
is being joined by remnants of the most powerful hurricane the National
Hurricane Center has ever measured.
At its peak off Mexico’s Pacific Coast, Patricia was a mighty Category 5 with 200 mph sustained winds.
“The remnants of Patricia should be absorbed by a non-tropical low
pressure system over southern Texas later tonight or on Sunday,” the
weather service said. In other words, what’s left of the storm is
feeding a lot of its moisture into Texas torrents.
Some flood warnings last late into the week, the weather service
warned. Even after the rain stops falling, creeks and rivers may
continue to overflow as runoff rushes through their banks.
Drought then flood
Much of Texas has suffered most of the year under the worst levels of
drought on the U.S. Drought Monitor, kept by the University of
Nebraska-Lincoln.
But the state has been inundated twice this year with extreme
rainfall. Over the Memorial Day holiday in May, rain and flooding was
blamed for at least 15 deaths in Texas and at least six in Oklahoma.
