What is black ice and why is it dangerous?

Black ice is a nearly invisible layer of ice on roads that makes them dangerously slick, often blending with the pavement and causing sudden loss of traction for vehicles.

What is the difference between freezing rain and sleet?

Freezing rain occurs when liquid rain freezes on impact with surfaces, while sleet forms when raindrops freeze before hitting the ground due to a deeper cold air layer.

What is the difference between a winter storm watch and a warning?

A winter storm watch is an early alert for potential severe weather within 24-72 hours, while a winter storm warning is issued when dangerous conditions are imminent or already happening.

Invisible Danger: Black Ice on Your Commute

As temperatures drop, winter weather hazards like black ice and freezing rain can transform commutes into perilous situations. Black ice, a thin and nearly invisible layer of frozen moisture on surfaces, poses a significant risk due to its tendency to blend with pavement, causing sudden loss of vehicle traction. This dangerous condition often forms at night or in the early morning, particularly on bridges and overpasses that cool faster.

Freezing rain occurs when liquid rain encounters subfreezing temperatures just above the ground, freezing instantly upon contact with roads and other surfaces, creating extremely slick conditions. This differs from sleet, where raindrops freeze while still in the air due to a deeper cold layer before reaching the ground. Understanding these phenomena is vital for safety.
