Dense freezing fog has prompted school closures and delays throughout Clark County.
The National Weather Service has issued a dense fog advisory in effect until noon today for the greater Portland and Vancouver areas, the south Willamette Valley and the lower Columbia and Interstate 5 corridor in Cowlitz County.
A spokesman at the National Weather Service says even after that fog lifts in the afternoon, it’s expected to crop up again in the evening hours.
“It might clear up for a bit in the afternoon but it will get right back into the soup tonight, said Gerald Macke, a meteorological technician at the National Weather Service. “The lifting of the fog will be short lived. With no wind out of the gorge, we can expect to see it again tonight and tomorrow.”
The fog is expected to limit visibility to a quarter mile or less at times, with freezing fog may lead to icy spots on roadways.
