The forecast shows Fiona approaching Bermuda late Thursday as a Category 4 hurricane with maximum sustained winds of 140 mph.
“Fiona is expected to affect portions of Atlantic Canada as a powerful hurricane-force cyclone late Friday and Saturday, and could produce significant impacts from high winds, storm surge, and heavy rainfall,” the hurricane center said. “Interests in these areas should closely monitor the progress of Fiona and updates to the forecast.”
Fiona’s swells also continue to affect the northern coast of Hispaniola, the Turks and Caicos, and the southeastern and central Bahamas.
“These swells will continue to spread westward across the southwestern Atlantic toward the northwestern Bahamas and the east coast of the United States during the next day or two. Swells from Fiona are expected to reach Bermuda by late tonight,” the hurricane center said. “The swells could cause life-threatening surf and rip current conditions.”
—Tropical Storm Gaston
Tropical Storm Gaston is maintaining its strength in the north central Atlantic, with maximum sustained winds near 65 mph with higher gusts, according to the hurricane center’s 8 p.m. advisory. Gaston is about 705 miles west of the Azores.
The storm, which is far from the U.S., is quickly moving northeast. An amplifying ridge associated with Fiona is expected to trap Gaston’s circulation late this week and this weekend. This could result in a clockwise loop and an eventual turn westward.
“It appears that the opportunity for strengthening has ended,” the hurricane center said. “A slow weakening trend should begin in the next day or so when Gaston moves over cooler waters and into a region of drier air and slightly stronger westerly vertical wind shear.”
Hermine is the next storm name on the list for the 2022 Atlantic hurricane season.
