A man walks through floodwaters in Austin, Texas, after heavy rains brought flooding to the area on Thursday, Oct. 31.
A ferocious and deadly storm system hurtled from Texas to the Northeast Thursday, lashing a long arm of the U.S. with buckets of rain and high winds, meteorologists said, as officials in four states postponed trick-or-treating to Friday.
Meteorologists warned people in the Ohio Valley, the lower Mississippi Valley and western Gulf Coast to brace for harsh gusts of wind, hail and even tornadoes — a scary forecast just in time for Halloween revelry.
All or parts of 16 states are under a wind advisory – and as the storm raced to the Northeast, it will intensify. The storm system has even forced some cities to cancel or delay Halloween. The Weather Channel's Mike Seidel reports.
"I think it's a good idea," said Tara Dudzik, a meteorologist for the National Weather Service in Indianapolis. "Winds of up to 60 miles per hour, and lightning - those are the main threats we'd be concerned about."
And Two men were killed as heavy rains across Central Texas swelled rivers and creeks and triggered flash flooding Thursday, prompting dozens of rescues across a region that's been dealing with a long, punishing drought.
Austin police reported that the body of a man 50 to 60 years old was found Thursday in the city's flooded Onion Creek. The body was found in a pile of flood-strewn debris Thursday afternoon, according to a police report.
Earlier, thee Caldwell County sheriff's office said a man died Thursday after driving on a low-lying portion of road overtaken by flooding. The victim was swept out of his vehicle in Dale, south of Austin.
No identities have been released for either man.
Some areas surrounding Austin were slammed by as much as 15 inches of rain, according to Austin-Travis County’s Emergency Medical Service (EMS). Meanwhile, emergency crews staged 15 water rescues across Austin and Travis counties throughout the early morning, EMS spokesman Warren Hassinger said.
On Thursday morning, an EMS team saved a pregnant woman cut off by two low-water crossings who had gone into labor, according to NBC affiliate KXAN in Austin.
Hassinger said there were reports from neighboring Hays and Comal Counties of people calling for help who were trapped in vehicles or clinging to trees.
The Texas Department for Public Safety said there were no firm numbers yet for the four worst affected counties of Williamson, Hays, Comel and Travis, but that there were at least 20 homes affected in Hutto, a town of more than 18,000 in Williamson County.
