NEW YORK – A region of central Texas by New York City was in a winter weather consultation on Thursday because an ice storm brought icy rain, dangerous conditions and power outages.
In Fort Worth, where the roads were slippery and icy, a congestion of at least 50 vehicles on Thursday morning led to multiple injuries, Mike Drivdahl, a public information officer for the Fort Worth Fire Department, USA TODAY said.
Millions propelled along a 1,500-mile trail as the storm moved overnight and moved to parts of Arkansas and Kentucky on Thursday morning. The national weather service can lead to half an inch of ice accumulation in some areas.
A mixture of rain and sleet is predicted to come to an end today, but not before it leaves a long amount of harmful ice accumulations, ‘the weather service said.
According to the weather service, the Ozarks can see a quarter of an inch of ice to the I-64 corridor in eastern Kentucky.
“This amount of ice is likely to lead to dangerous travel conditions, power outages and scattered tree damage,” the weather service said in a forecast.
During the Fort Worth crash, Drivdahl said first responders had to rescue several people from their vehicles with hydraulic tools. Injuries ranged from minor to critical, and some were transported to hospitals in the area. Drivdahl said there was no immediate confirmation of deaths. The incident took place around a toll lane separated by a concrete barrier that created a ‘funnel effect’.
“I’m sure it’s going to come down to some kind of chain reaction,” Drivdahl said. Sand and ice melt were needed to make the roads safe for first responders trying to gain access to the scene of the crash, he added.
