Ice Storm Warning: what it means and how often it is issued

The National Weather Service issued 38 ice storm warnings in 2025 and 25 a year on average in 2008-2025; Pennsylvania, Oregon and West Virginia got the most in 2021-2025. 2026 through September: 26, 51% above the average of 17 for those months in 2008-2025.

What is an ice storm warning?

An ice storm warning means freezing rain will build up enough ice to bring down trees and power lines and make travel dangerous. Each office sets the amount. A warning means the hazard is happening, about to happen, or very likely: act now to protect people and property.
