Winter weather can bring a variety of hazards, including snow, sleet, freezing rain, and icy roads, which can disrupt travel, damage property, and pose health risks. A Winter Weather Advisory helps residents and travelers prepare for these conditions.
This guide explains what a winter weather advisory is, the types of winter hazards, regions affected, and safety measures.

- Light to moderate snow accumulation
- Can make roads slippery and slow travel
2. Sleet
- Small ice pellets that bounce on impact
- Accumulate on roads and sidewalks, creating hazardous conditions
3. Freezing Rain
- Rain that freezes on contact with surfaces
- Can cause ice coating on roads, trees, and power lines
4. Wind Chill and Cold Temperatures
