Many state highways impassable

Oklahoma highway officials say many roads are impassable because of wintry weather, downed power lines or flooding.

Parts of western and central Oklahoma are under a winter storm warning until midday Monday, while flooding is a major concern in the southern and eastern part of the state.

The Oklahoma Department of Transportation says roads in northwest Oklahoma and Interstate 35 in central Oklahoma are slick and hazardous.

The National Weather Service says "disastrous" flooding will occur in eastern Oklahoma, where some areas received up to a foot of rain over the weekend. The state DOT says high water has caused the closure of some roads in counties in the southern and eastern part of the state.
