June 22,1972: Industries, including York facility, closed by devastating floods
Hurricane Agnes struck the northeastern United States on June 22, 1972 and proceeded to drop torrential rains which caused devastating floods over much of the region. As a result, 129 people were killed and hundreds of thousands more were left homeless. Damage from the hurricane totaled nearly $3 billion ($23 billion in today’s dollars).
While the storm was "only" a Category 1 (the weakest level) hurricane, it produced rain amounts of 19 inches in some locations. That fact, along with rivers that were already running high with snow melt, caused record flooding in several states.
Damage from the hurricane totaled nearly $3 billion ($23 billion in today’s dollars).
Pennsylvania was especially hard hit with fifty fatalities and over $2 billion in damages. The entire state was declared a disaster area. In York County, home of the York Division of the Borg-Warner Corporation (York was acquired by Johnson Controls in 2005), hundreds of people were forced from their homes, and industries (including the York plant) were shut down by the flooding rains.
Despite the muddy mess left behind by the storm, the York facility was back to operating at 80% capacity by June 25.
