Hurricane forecast update ups the ante in Atlantic
Veteran hurricane researchers at Colorado State University have updated their forecast for the 2024 Atlantic hurricane season, and it isn’t good news.
After predicting an active season in their initial outlook in April, CSU forecasters are doubling down, predicting even more storms before the season officially ends on Nov. 30.
And they said they have a higher amount of confidence in their forecast than usual.
The team of experts, led by Dr. Philip Klotzbach, have slightly increased the numbers in their forecast and “continue to call for an extremely active” rest of the season.
The reason? Continued near record-warm temperatures in the tropical Atlantic, and the likely emergence of La Niña during the peak of the season.
Hurricane Beryl is also to blame in a way.
Beryl was the second named storm of 2024 in the Atlantic, the first 2024 hurricane and the earliest Category 5 hurricane on record in the basin. Beryl made its third and final landfall on Monday on the Texas Coast as a Category 1 hurricane and killed at least 10 people in the U.S. alone.
The CSU team said Beryl, which also brought destruction in the Caribbean and on Mexico’s Yucatan Peninsula, is “a likely harbinger of a hyperactive season.”
There have also been two tropical storms so far this season: Alberto and Chris. Both of those were on the weaker side and made landfall on Mexico’s Gulf Coast.
Forecasters added that they believe there is a “well-above-average probability of major hurricane landfalls along the continental United States coastline and in the Caribbean” during the rest of the season.
The updated forecast now is expecting:
* 25 named storms (April outlook: 23)
* 12 hurricanes (April outlook: 11)
* 6 major hurricanes (April outlook: 5)
Here are the updated forecasts for U.S. landfall probabilities of a major hurricane (Category 3 or stronger storm):
* Entire U.S. coastline: 57 percent
* U.S. East Coast including Florida peninsula: 31 percent
* U.S. Gulf Coast (from Florida Panhandle westward): 38 percent
The CSU team thinks La Nina will make its presence felt during the peak of the season, which usually falls in September. La Nina tends to decrease wind shear in the tropical Atlantic, making it easier for storms to develop and intensify.
There also continues to be very warm water in tropical development hot spots across the Atlantic basin, which would only serve to fuel storms as they track westward.
The researchers also looked at Beryl, which formed much farther east much earlier in the season than what’s typical.
The report said that activity that deep in the tropics this early “is often associated with hyperactive seasons.”
The Atlantic hurricane season began June 1 and ends on Nov. 30.
NOAA issued its Atlantic season outlook in late May and is also expecting an active season:

NOAA forecasters plan to update their forecast in August.
