Ohio, Michigan, Pennsylvania, and New York Brace for Massive Lake Erie Seiche With Waves Up to 20 Feet
OHIO — Forecasters warn that another powerful seiche event is developing on Lake Erie, with early projections showing conditions that could rival November’s major episode — one of the biggest in years. Water levels near Toledo are expected to drop nearly 4 feet below low water datum, signaling a strong push of water out of the western basin and toward the eastern half of the lake.
Water Levels Expected to Plunge Near Toledo
According to early estimates, the water will be forced eastward by intense winds Thursday night into Friday morning. This rapid displacement could produce dangerously low water levels around the western basin, including Toledo and nearby coastal communities.
The forecast graphic highlights water levels plunging 48 inches below LWD, which can expose shoreline structures, create hazardous navigation conditions, and rapidly shift water masses across the lake.
Waves of 15–20 Feet Possible in Eastern Lake Erie
As the water rushes toward the east, the resulting rise could create extreme wave heights for areas downwind. Projections indicate:
- 5–10 foot waves developing from Toledo to Cleveland
- 10–15+ foot waves extending toward Erie
- Up to 20-foot waves possible near Buffalo and the eastern basin
These monster waves could impact shoreline roads, lakeside homes, breakwalls, and marinas across Ohio, Pennsylvania, and New York.
Timing: Thursday Night Into Friday Morning
Meteorologists emphasize that the prime window for this event appears to be late Thursday into early Friday, although refinements to the timeline are expected as updated data arrives.
Residents in shoreline communities along Ohio, Michigan, Pennsylvania, and western New York should monitor official alerts, secure loose items, and prepare for rapidly changing water levels and intense wave action.
