This is a question for meteorology buffs – as you may be aware, the Carolinas are being assaulted today by Tropical Storm Gaston.
Hurricanes usually form in the Tropical Atlantic, off the Cape Verde Islands, in a rather broad area of extremely warm ocean. They regularly form in the Caribbean and the Gulf of Mexico, though those storms are failry uncommon.
But Gaston formed from a stationary low sitting in the Atlantic off the coast of Georgia and Florida, in the bight of sorts that the coastline forms there.
And that is something I’ve never heard of happening before.
I’m aware of the theoretic possibility of tropical storms forming anywhere the water temperature is 27.5 C or higher and a low begins to form – but is Gaston just a bit uncommon, a “normal rarety” in the sense that something like this is known to happen, but only once every 50 years or something, or truly odd – like a Force 6 tornado, it’s theoretically possible but so improbable as to be inconceivable – until it happens.
