JEFFERSON CITY, MO - High winds and blowing snow across much of the state means motorists are advised to use caution if they venture outside today. The Missouri Department of Transportation reports that as of noon on Feb. 5, most state routes are still covered or partly covered with snow or ice."The additional snow accumulation overnight, combined with the strong winds means roads that were plowed yesterday will need additional effort today," said Beth Wright, state maintenance engineer. "Now that the heavy snow has stopped, we are already making progress and expect road conditions to improve throughout the day."While MoDOT's snow plow forces continue their 24-hour schedule, motorists should be advised that it may take some time before Missouri state routes return to normal conditions. It's also possible motorists may encounter slick spots due to refreeze or where blowing snow covers an already-plowed roadway."The colder it is, the less effective our materials become," said Wright. "At 30 degrees, one pound of salt melts 46 pounds of ice, but that same pound of salt melts less than four pounds of ice when it's zero degrees."MoDOT uses abrasive materials, such as sand, in combination with salt to help provide traction on snow-covered roadways when bitterly cold temperatures occur.One of the best ways to prepare for winter travel is to check MoDOT's Traveler Information Map, located at www.modot.org.
