The sea could be unleashed from Florida to Newfoundland. Erin will not touch land directly, but the hurricane will still demonstrate all its strength.
The most powerful …. so far
Hurricane Erin, who already stands out as one of the most imposing phenomena of the 2025 season, continues its progression above the Atlantic. If its center should not hit the coasts, neither American nor Canadian directly, its effects will nevertheless be felt over several hundred kilometers, even in the Atlantic provinces.
Water walls
What particularly worries experts are the colossal waves generated by the system. Fucked by winds up to 175 km/h and the exceptional heat of ocean waters, Erin could give birth to water walls reaching 30 meters in height. We therefore speak of the equivalent of a ten -story building. Even if these extreme waves will form mainly offshore, the swell they will generate will travel the ocean to strike the North American coast, from the American coast to Nova Scotia and even Newfoundland.
To Newfoundland
In Canada, meteorologists expect particularly agitated seas at the end of the week. Nova Scotia and Newfoundland, in particular, will see their shores exposed to a long and powerful swell, capable of accentuating coastal erosion and making the navigation perilous. Even without direct landing, Erin can transform fishing areas and Atlantic ports into risky sectors. Lovers of beaches, on the other hand, will have to be extremely vigilant: the return currents generated by this swell are considered one of the main threats to the safety of bathers.
Bad memories
Recent history also recalls how many such waves can upset the daily life of coastal regions. In 2019, Hurricane Dorian had projected waves of almost 20 meters on the islands-the-Madeleine, causing major erosion and considerable damage. Three years later, Fiona had in turn left her mark: offshore, some waves had come close to 30 meters, an intensity worthy of the most powerful storms of the North Atlantic.
The strength of the water
With Erin, the current scenarios evoke a similar context. Even if the inhabitants of Atlantic Canada will probably not have to undergo destructive winds on the ground, they will have to compose with a raging sea, weakened shores and a sometimes dantesque swell. The storm acts as a reminder: in this part of the world, the power of hurricanes is measured as much by what they leave in the water as by what they unleash in the air.
