Freezing Drizzle Explained: Tiny Drops, Big Ice Problems
What freezing drizzle is, why it can glaze roads and sidewalks, and how it differs from freezing rain and snow.
Quick answer: Freezing drizzle is made of tiny liquid droplets that freeze on contact with surfaces below freezing.
Why it forms
Freezing drizzle can occur in shallow clouds that lack enough ice crystals to produce snow.
The droplets remain liquid until they hit cold roads, trees, or sidewalks.
Why it is dangerous
Amounts may look minor, but a thin glaze can make roads and steps extremely slick.
It can happen with little visual drama compared with snow.
Safety
Treat freezing drizzle advisories seriously and slow down before bridges, ramps, and untreated surfaces.
Pedestrians should watch for invisible glaze on steps and sidewalks.
