Flash fog is a meteorological phenomenon characterized by the very rapid and sudden formation of dense fog, often reducing visibility to near zero within minutes.
It typically forms when a mass of warm, moist air suddenly encounters a much colder surface or air mass, causing rapid condensation of water vapor into tiny droplets.
The primary danger is the extreme and sudden reduction in visibility, which creates hazardous conditions, particularly for transportation, leading to a higher risk of accidents.
Drivers should immediately slow down, turn on low-beam headlights (not high beams), use fog lights if available, increase following distance, and avoid sudden braking. If possible, pull over safely.
