...Reduced Visibilities From Snow Bands Across the I-15 Corridor...

Current radar shows snow bands moving across the I-15 corridor
between Shelby and Brady, reducing visibilities down to below a
mile at times. Expect additional snow bands to continue to bring
sudden changes in visibility to below a mile at times, and light
snow accumulations over the next few hours along I-15 between
Great Falls and Shelby. For those traveling, be prepared for
sudden changes in visibility and road conditions.
