Shreveport, Louisiana – Even small amounts of ice accumulation could lead to significant impacts across north Louisiana and the ArkLaTex, including downed trees and power outages, according to the National Weather Service.
In a recent briefing, the National Weather Service in Shreveport warned that as little as one-quarter inch of ice can begin bringing down tree branches and power lines. Officials note that some forecast models are indicating between one-half inch and one inch of ice accumulation in portions of the region, which would significantly increase the risk of widespread damage.
The NWS outlines a clear progression of impacts as ice accumulates. Trace to one-tenth inch of ice can lead to slick roadways, coated sidewalks, and icy windshields. Around one-quarter inch, isolated power outages and fallen tree limbs become more likely. At one-half inch, damage becomes more dangerous, with widespread power outages and moderate damage to trees and power infrastructure possible. Ice accumulations near or above one inch are considered potentially devastating, with long-duration power outages and severe tree damage.
Officials emphasize that ice storms often cause more damage than snowstorms due to the added weight on trees, power lines, and structures. Travel conditions can deteriorate rapidly as bridges and overpasses ice over, even before significant accumulation is visible.
Residents are encouraged to prepare for possible power outages by charging devices, ensuring access to emergency supplies, and avoiding unnecessary travel if freezing rain develops. Those with trees near homes or power lines should remain alert for falling branches during icing conditions.
