The 1998 Ice Storm

The 1998 Ice Storm was one of the most destructive natural disasters in North American history. In early January 1998, an unusual weather pattern brought five consecutive days of freezing rain to eastern Canada and the northeastern United States. This storm coated everything in up to 4 inches of solid ice.

Freezing rain occurs when supercooled water droplets fall through a layer of cold air near the ground. These droplets remain liquid even though their temperature is below freezing. When they hit surfaces like trees, roads, or power lines, they instantly freeze into a layer of ice called glaze ice. During the 1998 storm, ice accumulated day after day. Evidence shows that some areas received over 100 millimeters of freezing rain, far more than most infrastructure can withstand.

The weight of the ice caused catastrophic damage. Over 1,000 electrical transmission towers collapsed under the enormous load. These tall metal structures carry high-voltage power lines across long distances. When they fell, they created a domino effect that knocked down other towers. About 4 million people lost electrical power. Some communities remained without electricity for more than a month during the coldest part of winter. Scientists explain that the combination of prolonged freezing rain and vulnerable infrastructure made this disaster especially severe.

The storm's impact extended beyond power outages. Trees snapped under the ice weight, blocking roads and damaging buildings. The disaster killed 35 people and caused between $4 and $6 billion in damage. Emergency workers struggled to restore services in dangerous conditions. The 1998 Ice Storm demonstrated how natural hazards can severely disrupt modern society. Understanding these events helps communities prepare better infrastructure and emergency response plans for future extreme weather.

Interesting Fact: Some transmission towers accumulated over 110 pounds of ice per foot of cable. That weight is similar to having a large adult sitting on every foot of power line.
