How many hurricanes in 2024? La Niña could mean active season in the Atlantic
The average number of named storms from 1991 through 2020 in the Atlantic basin (including the east coast of the United States and the Gulf of Mexico) is 14.
Posted — UpdatedWhat is La Niña weather? What is El Niño weather?
Through the spring of 2024, the east coast will be in an El Niño period, but it is weakening.
NOAA expects that La Niña could take over during the June-July-August time frame.
It's very common to have a quick transition from an El Niño to a La Niña.
The hurricane impacts of El Niño and its counterpart La Niña are like a see-saw.
El Niño means stronger hurricane activity in the Pacific, while La Niña indicates stronger hurricane activity in the Atlantic Ocean.
During a La Niña pattern, WRAL meteorologist Kat Campbell says, "It's easier for storms to form and easier for them to strengthen. One of the reasons why is we have stronger westerly trade winds and that lowers the vertical wind shear."
Stronger vertical wind shear tears tropical systems apart. Weaker vertical wind shear is less able to pull apart a hurricane or keep it from organizing into a strong storm.
"It's not a guarantee that we will have a La Niña for the tropical season, but all signs are pointing in that direction," WRAL meteorologist Aimee Wilmoth said.
