LIVE: Power Crews Mobilize, Prepare for Ice Storm Underway

An ice storm, which could be the worst to hit the U.S. in years, is unfolding across portions of the southern Plains this week.

The most significant icing is expected from Texas to Kentucky through Friday. Widespread power outages are likely as ice weighs down tree branches and power lines, while treacherous travel is developing in areas receiving freezing rain, sleet and snow.

"In some locations, the storm has the potential to allow one half an inch or more of ice to accumulate on the ground and accrue on elevated surfaces," AccuWeather.com Expert Senior Meteorologist Alex Sosnowski said.

Power suppliers in the path of the ice storm are mobilizing in anticipation of major power outages. Entergy Arkansas, Inc., which serves nearly 700,000 customers in 63 counties of Arkansas, lies in the zone expected to receive ice for the longest duration.

"With a major storm that affects a large area of our territory, power restoration for all customers could take between five to seven days to complete, with the majority of customers being back in service much sooner than that," said Brady Aldy, transmission and distribution operations director for Entergy Arkansas, Inc.

In a press release, Entergy Arkansas, Inc., said they are bringing in 6,700 workers to prepare for the storm.

According to Alabama Power, crews are heading to Texas on Thursday in order to help respond to power outages in the path of the ice storm.
