The National Weather Service in Hastings issued a dense-fog advisory October 30 for eight Nebraska counties, warning that reduced visibility could make overnight and Saturday-morning driving hazardous.
The advisory covers Greeley, Howard, Nance, Sherman, Valley, Buffalo, Dawson and Gosper counties. It takes effect at midnight Central Daylight Time at the start of Saturday, October 31, and is scheduled to end at 11 a.m. CDT that morning.
Forecasters said visibility could fall to one-quarter mile or less. The bulletin was issued at 7:18 p.m. CDT Friday; its issue time is separate from the midnight start of the advisory period.
The Weather Service advises drivers in fog to slow down, use headlights and leave additional space between vehicles.
The notice describes expected low-visibility conditions within its listed counties. It does not establish that visibility is already equally poor throughout the advisory area, or that conditions will improve everywhere precisely at the scheduled ending time.
