U.S. midsection grapples with pesky ice storm ; more on the way 美國中部對付惱人的冰風暴；更多冰風暴接踵而至
Parts of the central U.S. grappled Saturday with a second day of road-glazing ice and braced for more of the treacherous, below-freezing wintry weather expected to close out the holiday weekend.
The storm created travel headaches for many people who opted to go out despite pleas by authorities to stay put. The Oklahoma Highway Patrol said Interstate 40 was closed in two places in western portions of the state because of wrecks, including the jackknifing of several tractor-trailers in icy conditions in Caddo County. There were no immediate reports of injuries.
State troopers in Missouri and other affected states were pressing motorists to limit travel to only necessary outings, allowing road crews the space to treat the slippery mess. Many appeared to heed that advice, drawing kudos from the Missouri Department of Transportation, which scrambled around-the-clock to mitigate the glazed roads.（AP）
