CHICAGO (STMW) – Dense fog continues to blanket the area causing limited visibility for motorists, according to the National Weather Service. It has also been declared an air pollution action day.
A dense fog advisory issued early Monday remains effect until 10 a.m. Tuesday for northern Illinois — including Cook, DeKalb, DuPage, Kane, Kankakee, Lake, McHenry and Will, according to the National Weather Service’s Web site.
A dense fog advisory means visibilities will frequently be reduced to less than one-quarter of a mile, the weather service said.
No fog-related accidents have been reported as of 2:45 a.m. Tuesday, according to police News Affairs Officer Ron Gaines.
Illinois State Police personnel received several phone calls asking for advice for driving in low-visibility conditions — but all ISP Districts have also reported no accidents caused by the weather as of 2:45 a.m.
Callers to the Chicago District State Police office have not been advised to stay off the road as of early Tuesday morning, according to Trooper Ivan Bukaczyk.
“We’re not encouraging people to stay off the road,” Bukacyzk said. “If drivers have fog lamps, we’re encouraging they use those. Also, give yourself plenty of following distance so you have advanced warning and adequate room to stop should you need to.”
Drivers should not drive with their high beams on, Bukacyzk said.
Widespread fog is expected to continue developing early Tuesday as temperatures will remain just above freezing. The fog is expected to mostly be gone by 9 a.m. Tuesday, when temperatures will reach the mid-40s with showers “likely” in the afternoon.
Tuesday will also be an Air Pollution Action Day and the weather service has issued an air quality alert. The day is declared when widespread particle matter levels are expected to be above the unhealthy level for sensitive groups.
The weather service advised motorists to slow down, use headlights and leave plenty of distance between vehicles.
