Tropical Storm Fiona has formed in the Atlantic, becoming the sixth named storm of the 2022 Atlantic hurricane season, the National Hurricane Center said.

The storm, packing winds of 50 mph with even higher gusts, was only about 75 miles east of Guadeloupe, late Friday morning.

The tropical storm conditions (winds 39 mph or higher) which extend 140 miles from the center of the storm have prompted multiple governments across the northern Leeward Islands to issue tropical storm warnings.

A tropical storm watch has been issued for the US Virgin Islands and Puerto Rico, including Vieques and Culebra, according to the National Hurricane Center.

They also cover Antigua, Barbuda, St. Kitts, Nevis, Montserrat, Anguilla, Saba, St. Eustatius, St. Maarten, Guadeloupe, St. Barthélemy, and St. Martin.

A tropical storm warning means that tropical storm conditions are expected somewhere in the warning area within 36 hours.

“Tropical storm conditions are expected across portions of the Leeward Islands within the warning area beginning this afternoon and will spread westward to the US Virgin Islands on Saturday and across Puerto Rico late Saturday and Saturday night,” the NHC wrote.

A tropical storm watch is in effect for Dominica, the south coast of the Dominican Republic from Cabo Engano westward to Barahona and the north coast of the Dominican Republic from Cabo Engano westward to Cabo Frances Viejo.

A watch means tropical storm conditions are possible within the next 48 hours.

“The center of Fiona is expected to move across the Leeward Islands Friday night and early Saturday, and move near the Virgin Islands and Puerto Rico late Saturday into Sunday,” the hurricane center wrote.

The storm could fluctuate in strength through the weekend, but isn’t anticipated to strengthen significantly.

Flash floods and mudslides are big concerns

Fiona’s primary impact will be heavy rain from the Leeward Islands to Puerto Rico. Flash flooding of urban areas and mudslides in the higher terrain will be possible due to 4 to 6 inches of rainfall, with isolated amounts of over 10 inches, according to the center.

Flash flooding explained: What it is and why it's so dangerous

Flash flooding of urban areas and mudslides in the higher terrain will be possible due to 3 to 10 inches of rainfall, with isolated amounts topping 16 inches, according to the center.

“Considerable flood impacts are possible across eastern portions of Puerto Rico,” the National Hurricane Center warns.

Here is a breakdown of how much rain is expected in each location according to the NHC.

  • Leeward Islands and Northern Windward Islands: 3 to 6 inches
  • British and US Virgin Islands and Puerto Rico: 4 to 6 inches with local maximum totals of 10 inches
  • Eastern Dominican Republic: 6 to 10 inches with maximum totals of 16 inches possible
  • Turks and Caicos: 4 to 8 inches

By early next week, the system is forecast to be near Hispaniola, where watches may be required later on Friday, the NHC said.

The forecast now calls for Fiona to reach hurricane status by mid-week north of Turks and Caicos.

Beyond that time period, the computer forecast models have it linger east of the Bahamas for days. Still, then they disagree on where it goes next. It is undoubtedly a storm to watch, especially if you live on the east coast of the US.
