(CNN)Hurricane Epsilon has strengthened to a major, Category 3 storm as it moves toward Bermuda, threatening the island with dangerous swells.
With winds sustained at 115 mph on Wednesday afternoon, Epsilon is the fourth major hurricane of the 2020 season, along with Laura, Teddy and Delta.
Epsilon is forecast to approach but stay east of Bermuda, where its powerful winds could still be felt and have prompted a tropical storm warning. It is not expected to affect any other land when it turns northward.
"Tropical storm conditions are expected on Bermuda beginning (late Wednesday) and continuing intermittently through late Thursday, when Epsilon is forecast to make its closest approach east of the island," the National Hurricane Center said.
Large swells created by the storm could also affect the island over the next few days, the center said.
"These swells are likely to cause life-threatening surf and rip current conditions," it added.
Epsilon's hurricane-force winds currently extend up to 25 miles out from the center while tropical storm-force winds extend up to 450 miles out, it added.
Epsilon, which formed in the Atlantic Ocean on Monday, is now the 10th Atlantic hurricane this year -- making 2020 only the 5th time since 1966 that this has happened. The last time there were 10 hurricanes was 2017.
Epsilon is the 26th named storm of the 2020 Atlantic hurricane season, which ends on November 30.
