Wider weather episode

As an arctic air mass continued to build southward across the South on February 17th, another wave of precipitation overspread this cold air mass across northeast Louisiana. The main impacts across this portion of the state were from freezing rain and resulting heavy icing, but some significant accumulations of sleet and snow also occurred. Freezing rain continued through the evening hours. Ice accumulated quickly in many locations and downed numerous trees, large limbs, and power lines. Several trees and limbs fell onto power lines, resulting in more widespread power outages as well. Significant impacts to travel and electrical infrastructure occurred in the hardest hit areas. In the Vidalia area, heavy rain flooded several roads due to ice-blocked drainages.
