Record-Breaking Dense Fog Engulfs U.S., Affecting Over 100 Million People

Unprecedented fog event linked to climate change disrupts travel and daily activities across the nation.

Dense fog alerts have reached record levels for the third consecutive day, impacting over 90 million people across the United States.
The fog is a result of a storm drawing large amounts of moisture from the Gulf of Mexico over a layer of cooler air left by last week’s Arctic blasts.
Visibility has been reduced to a quarter mile or less in many areas, causing disruptions in flights, vehicle accidents, and school delays.
The fog is expected to persist throughout the week, affecting 100 million people in the U.S. and Canada.
The unusual weather pattern is linked to unseasonably warm temperatures and rapid snow melt due to climate change.
