Special Weather Statement issued October 17 at 4:48AM MDT by NWS Pocatello ID
Additional Details Here.
At 448 AM, satellite, webcams, and weather stations were monitoring several localized patches of dense fog from the Snake Plain up toward the Montana border. Particular trouble spots have included Interstate 15 just south of Monida Pass, Interstate 15 just north of Idaho Falls, Highway 20 between Idaho Falls and Idaho National Laboratory, and Highway 26 between Blackfoot and Idaho National Laboratory, where visibilities have ranged from 1 mile to as low as one-tenth of a mile at times. Model guidance suggests these localized pockets of dense fog will continue through 10 AM. If traveling or commuting in these areas, be prepared to encounter sudden drops in visibility. When driving into fog, slow down and use low beam headlights. As we are just moving into our cold season where fog starts to occur more frequently, keep in mind that some drivers may not be used to dealing with fog. Use extra caution to watch for other vehicles and hazards.
