Expect dense fog to stick around this week
The fog that made the commute more hazardous for drivers around the Puget Sound Monday morning is expected to last through at least part of the week.
KIRO 7 Meteorologist Nick Allard told Seattle’s Morning News that a temperature inversion is causing the fog. Essentially, cold air is trapped at the surface with warmer air higher up.
“So instead of cooling with height, you warm with height,” Allard explained.
The phenomenon caused dense fog around Central Puget Sound and the southern interior Monday morning. The National Weather Service says visibility was down to one-eighth of a mile in some areas.
The National Weather Service reports the fog will likely impact flights around the region as well.
