Gaston, the seventh tropical storm of the 2022 Atlantic hurricane season, formed over the north-central Atlantic on Tuesday – but away from any landfall.
Forecasters are also watching two disturbances, and a high probability of turning into a tropical depression over the next several days and may be something to watch for for Florida.
Here’s what to know:
Tropical Storm Gaston Forecast
According to a 5 p.m. advisory from the National Hurricane Center on Tuesday, Tropical Storm Gaston was about 990 miles west of the Azores.
The system had maximum sustained winds near 40 mph, and forecasters told Gaston for winds to strengthen to about 60 mph before moving out over the next few days. It is not expected to become a hurricane.
“Interests in the Azores should monitor the progress of the system,” the hurricane center said.
Forecasters expect the system to become extra-tropical over the weekend once cold waters, dry air and westerly shear increase.
What about two turbulences?
The disturbance that forecasters are closely monitoring is a few hundred miles east of the Windward Islands on Tuesday afternoon and continues to show signs of organization.
The Hurricane Center said conditions are favorable for it to turn into a tropical depression within the next few days as it rapidly moves from west to west-northwest across the eastern and central Caribbean Sea.
In its advisory at 2 p.m. Tuesday, the Hurricane Center raised the system’s chances of formation to 40% to 60% for the next 48 hours and 70% to 80% over the next five days.
“Interests in the Windward Islands should closely monitor the progress of this system as heavy rainfall and strong winds could affect these islands beginning Wednesday,” the Hurricane Center said.
Forecasters are also seeing a tropical wave that is forecast to move off the west coast of Africa in a couple of days. The Hurricane Center says it has no chance of forming in the next 48 hours and has a low 20% chance of forming as it moves north between West Africa and the Cabo Verde islands by the end of the week.
Hurricane Fiona Forecast
Reaching Cat 3 level strength, Fiona has become the first major hurricane of the 2022 Atlantic hurricane season. It poses no threat to Florida or to the rest of the United States.
According to a National Hurricane Center advisory at 5 p.m. Tuesday, the storm was about 50 miles west of North Caicos with maximum sustained winds of 115 mph. It was crawling to the north-northwest at 8 mph, slowing earlier Tuesday. It is likely to turn northwards on Tuesday night or Wednesday.
“On the forecast track, the center of Fiona will continue to move near eastern Turks and Caicos during the next few hours, away from those islands by tomorrow, and reach Bermuda late Thursday,” the hurricane center said.
For the next several hours, Fiona will continue to bring hurricane status to parts of Turks and Caicos and tropical storm status to parts of the southeastern Bahamas, according to the Hurricane Center.
Forecasters expect Fiona to strengthen into a Category 4 hurricane by Wednesday night as it moves through Atlantic waters. The forecast shows the system as Cat 4 as long as it is near Bermuda with maximum sustained winds of 130 mph.
Turks and Caicos are under a Hurricane Warning and a Tropical Storm Warning is in effect for the southeastern Bahamas. Bermuda is under a tropical storm watch.
