May 25, 1980 ash fall East County

Most interesting was the medium vulnerability rating in the Grays Harbor County plan.

While prevailing winds nearly always would carry ash fall east away from this county, its vulnerability determination appears based on the May 25, 1980 ash fall from Mount St.Helens. The county’s plan stated this event deposited from one-quarter to three quarters of an inch of ash in the east-county area leading to power outages, hazardous travel conditions, and stranded tourists.

This is from the Analysis of Local Hazard Vulnerability which is part of Washington State Enhanced Hazard Mitigation Plan.

Imagine that - ash fall here in the area that could cause dangerous conditions.
