TAMPA, Fla. (WFLA) — Crossover tropical cyclones, storms that traverse from one ocean basin to another, are a rare meteorological phenomenon.
Since records began in 1851, only 21 such storms have been documented. These storms either start in the Pacific and move into the Gulf of Mexico or the Caribbean or vice versa.
Only about 2% out of all Atlantic basin hurricanes recorded are crossover storms.
The occurrence of TWO crossover storms in a single year is even more exceptional, having happened only twice before 2024, once in 1988 and again in 1996.
This is the first year that two storms have crossed over from the Caribbean to the Pacific and the Pacific into the Gulf of Mexico.
This year, Tropical Depression Eleven-E formed in the Pacific near the southern Mexican coast. It crossed over into the Gulf of Mexico and became one of the strongest Hurricanes in the Gulf of Mexico, Hurricane Milton.
Tropical Storm Nadine formed in the Caribbean and moved across Central America, reforming as Hurricane Kristy in the Pacific.
