Power company crews were being mobilized to deal with potential outages.
Appalachian Power spokesman Phil Moye said Sunday that in addition to putting its own workers on notice, more than 350 crews have been secured from others companies within the system of parent American Electric Power, which serves nearly 440,000 customers in 24 West Virginia counties.
"The weather pattern certainly looks like it could impact our service territory and cause power outages," Moye said. "If the weather continues to develop in a way that we could have major power outages, then we'll request more (help)."
West Virginia already has had a busy year dealing with weather-related emergencies. The June 29 windstorms known as a derecho left more than 680,000 state customers without electricity, many for up to two weeks, in the middle of a heat wave.
"With an event this size, the power company is going to be so tied up and they're not going to be able to get to everybody at the same time," Miller said. "So they need to be as ready as they can."
Airlines canceled 19 flights heading in and out of Charleston's Yeager Airport on Monday due to the pending storm. Most involved United Airlines flights and 11 of the canceled flights involved airports in Washington D.C. The other airports are in New York, Chicago and Houston.
Another United flight scheduled to leave Yeager Airport on Sunday night also was canceled.
