| Powerful Hurricane Milton in the Gulf of Mexico last October on its way to devastating parts of Florida. Forecasts predict another busy hurricane seasons in 2025. The season start June 1 |
The NOAA forecast is for 13 to 19 named storms; six to 10 hurricanes and three to five major hurricanes during this season, which officially begins June 1.
Major hurricanes have sustained winds of at least 111 mph.
The average season has 14 named storms, seven of which develop into hurricanes.
NOAA's forecast is actually a game of chances. They give a 60 percent chance that this season will be busier than normal, a 30 percent chance that it will be close to average and a 10 percent chance it will be on the light side.
At least in recent years, "normal" hasn't really happened, Every Atlantic hurricane season has produced more storms that average, a standard based on data from 1990 to 2020, reports CBS News. Four of those season only produced two or three major hurricanes, which is at or slightly below normal for the particularly strong storms.
REASONS WHY
Several factors went into 2025's forecast for above normal activity.
Neither El Nino or La Nina is going on in the Pacific. These two phenomenon affect ocean temperatures off the west coast of South America and have worldwide effect on the weather.
An El Nino tends to suppress Atlantic hurricanes because it creates stronger upper level winds over the areas of the Atlantic where hurricanes develop. Those strong upper level winds tear apart the thunderstorms that are essentially baby hurricanes, preventing them from developing.
The neutral conditions in the Pacific mean those strong upper level winds in the Atlantic are less likely in the late summer and fall, so tropical storms would have a better chance of developing.
There's warmer than average water in most of the areas where hurricanes tend to develop. Warmer water is jet fuel for hurricanes, helping them develop and get stronger. Though this year the water isn't quite as hot as it was in 2024, which proved to be a hyperactive hurricane season despite an odd lull in activity during August.
That might mean 2025 might be busier than usual, but not insane.
Finally, monsoon activity in West Africa is forecast to be above normal.. Disturbances coming off west coast of Africa emerge into the Atlantic and sometime develop into hurricanes. The more of these disturbances that head into the Atlantic, the greater the chance that some of them will develop into hurricanes.
OTHER FORECAST
The closely-watched Colorado State University hurricanes season forecast also call for an above normal 2025.
Their forecast, issued April 3. predicts 17 named storms, nine hurricanes and four major hurricanes. The University will offer an updated seasonal hurricane forecast on June 11
Ominously, Colorado State says there's an above normal chance of a major hurricane hitting the U.S. coastline in 2025.
We're already had an unusually high number of major, destructive hurricanes hitting the United States in recent years.
They include hurricanes that cost $1 billion or more like Harvey (Texas) and Irma (Florida) in 2017; Michael (Florida), 2018 Laura and Zeta (Louisiana) in 2020; Ida (Louisiana) 2021; Ian (Florida), 2022; Idalia (Florida, 2023) and Helene and Milton, (both Florida), 2024.
As you can see, Florida in particular has been especially punished in recent years. So the prospect of more major hurricanes hitting that state has to strike a nerve,
Forecasting where hurricanes will go before the season starts is exceedingly difficult. Meteorologists can detect patterns that could tell where these storms are a little more likely to go, but all kinds of factors can make that happen, or make that not happen.
Though hurricane season starts June 1, the storms are usually relatively infrequent until August hits. (In some years, tropical storms can form before June 1) In the short term, no tropical storm developing is in the forecast for at least the next seven days.
