Expect 1-2 Feet Of Lake-Effect Snow<\/p>\n

Winter Storm Ezra brought 60\u2013 to 80-mph wind gusts, blinding snow and subzero temperatures, but it also delivered something especially fascinating along Lake Erie: a seiche (pronounced \u201csaysh\u201d).<\/p>\n

Imagine picking up a bathtub and sloshing it back and forth horizontally. That\u2019s essentially what happens during a seiche. Water piles up dramatically on one side of a lake while water levels drop sharply on the other.<\/p>\n

Here\u2019s how it happened:<\/p>\n

On Monday, winds gusting up to 80 mph blew across Lake Erie for several hours, pushing enormous amounts of water toward the eastern end of the lake. In Buffalo, New York, water levels surged by nearly 8 feet, flooding shorelines and producing freezing spray as waves crashed ashore in subfreezing air.<\/p>\n

That freezing spray coated trees, benches and shoreline infrastructure in ice, causing damage, according to The Weather Channel\u2019s former winter weather expert Tom Niziol.<\/p>\n

Meanwhile, 225 miles away on the western end of the lake, Toledo, Ohio, experienced the opposite effect.<\/p>\n

As water was forced east, Lake Erie\u2019s western basin was essentially drained. Water levels dropped by about 6 feet, exposing bare lakebed and revealing shipwrecks typically hidden beneath the water. That’s a net difference of roughly 13 feet from one end of the lake to the other.<\/p>\n

Locals ventured out to take photos of the unusual sight.<\/p>\n

But that water doesn\u2019t stay away forever. Once winds relax, the displaced water rushes back, sloshing across the lake and often oscillating for hours before finally settling.<\/p>\n

Seiches On Lake Erie Aren\u2019t Unheard Of<\/p>\n

Lake Erie typically experiences a strong seiche every few years when powerful winds blow from southwest to northeast, which perfectly aligns with the long, narrow shape of the lake.<\/p>\n

Lake Erie stretches roughly 225 miles long, but is only 40\u201350 miles wide and is the shallowest of the Great Lakes. That combination makes it especially susceptible to dramatic water movement during strong wind events.<\/p>\n

In December 2022, Winter Storm Elliott triggered a major seiche on Lake Erie, causing water levels to drop to their lowest on record, according to the National Weather Service.<\/p>\n

While the phenomenon can be jaw-dropping to witness, seiches can also be dangerous. Rapidly rising water levels can lead to flooding, shoreline damage and hazardous conditions. Over the years, seiches on the Great Lakes have caused extensive property damage \u2014 and in some cases, even claimed lives.<\/p>\n
