As fall progresses, solar energy shifts from the Northern Hemisphere to the Southern Hemisphere and more northerly latitudes rapidly cool down, Trepanier explains. Hurricane Eta hit Nicaragua as a category 4 storm, followed two weeks later by another category 4 hurricane, Iota.Īny storms that do form in November tend to be weaker for the same reasons they are somewhat rare. More recently, “November was crazy in 2020,” Truchelut says, thanks to exceptionally warm waters in the Caribbean. Three November storms, one of them a hurricane, formed in 2005. There are some years that are true outliers. during November going back to 1851, he says, so on average such a landfall would happen about every 10 to 15 years. Only 10 tropical storms and three hurricanes have struck the U.S. landfall activity,” says Ryan Truchelut, a meteorologist and co-founder of WeatherTiger, a private weather-forecasting group. That drop means November is also “the quietest month from the perspective of U.S. Storm activity “starts to decline pretty quickly once November 1 hits,” says Jill Trepanier, a hurricane researcher at Louisiana State University. The season peaks sharply from the end of August through early October, when ocean warmth at end of summer coincides with wind conditions that are generally more favorable to storm formation. Hurricane season, which begins on June 1, brackets the time of year when atmospheric and ocean conditions are most suitable for storm formation. And storms can form even after that point, as notably happened during the blockbuster 2005 season when Tropical Storm Zeta shockingly formed on December 20 and lasted until January 6. Though such tropical systems are less common at this time of year, the official Atlantic hurricane season actually lasts through November 30. It’s generally not a time people associate with destructive tropical cyclones churning toward the U.S.-but that’s exactly what is happening as Tropical Storm Nicole bears down on Florida, where it is expected to make landfall as a hurricane. November weather in most of North America is synonymous with chilly breezes rustling through red, yellow and orange leaves as fall edges closer to winter.
