Snow, strong winds, below zero temperatures and dangerous wind chills could create hazardous travel conditions, with near-zero visibility.
We are currently sliding into a really deep freeze that, if a traveler doesn't plan right, could turn deadly. Much of the northwest part of the state already has experienced snowfall of as much as five to 10 inches. Winds have increased through the afternoon and are expected to reach 20-40 mph today, creating dangerous wind chills.
As the snow diminishes through the day on Wednesday, temperatures will continue to fall. Combined with the strong winds, that could create dangerous wind chills and life-threatening conditions for anyone caught in the open. Even in areas of the state where the snowfall is less heavy, actual temperatures and wind-chill readings well below zero are expected.
This weather combination will create hazardous driving conditions, including near zero visibility at times. Roads are already snow covered and slippery in many areas and conditions will continue to deteriorate during the overnight hours. Drivers can also expect drifting snow, especially in sheltered areas and at the ends of bridges.
Travelers should be alert to changing conditions and be prepared to adjust travel plans if necessary.
"This is a significant winter storm that is going to make travel extremely difficult at times throughout much of the state overnight and through Wednesday," says Transportation Secretary Darin Bergquist. "Conditions will deteriorate rapidly as the storm moves through South Dakota and people should make plans to stay put or extend their stay until it is safe to travel."
People who must travel should drive with extreme caution and are encouraged to visit www.safetravelusa.com/sd or dial 511 to check the latest road conditions and travel advisories before heading out.
Motorists are reminded that SDDOT crews will maintain roads until early evening hours as conditions allow. After that, winter maintenance will be suspended and resume early the next morning, weather permitting.
If you must travel, the departments of Transportation and Public Safety recommend travelers also take the following steps.
