A snowstorm dumped around two feet of snow in parts of the Permian Basin in West Texas and New Mexico over the weekend, crimping some crude output and leaving roads dangerous for trucks heading to and from oil wells, forecasters and companies said on Monday. Snow had stopped accumulating by Monday afternoon but "travel continues to be impacted as most roads are slick and snow-covered," and some roads across southeastern New Mexico were still closed, according to a notice from the National Weather Service's Midland, Texas, office.
