Forecasters are getting ready for a busy hurricane season in 2024. Here's why

Some forecasters are calling for an above-average hurricane season. Here's a closer look.

WASHINGTON — Forecasters are gearing up for what could be a busy hurricane season.  While the official forecast from the National Oceanic and Atmospheric Association won't be released until May 23, early indications are that the atmosphere will be primed for above-average activity. 

Colorado State University tropical meteorology experts are calling for an "extremely active" season.  CSU is calling for 23 named storms, 11 hurricanes, and five major hurricanes.  A major hurricane is classified as Category 3 and above.  On average, the Atlantic basin sees 14 named storms, seven hurricanes, and three major hurricanes. 

Why so busy?

The short answer: Very warm water and a potential lack of wind sheer.  Hurricanes love warm water. It helps to provide energy for the storm. Water temperatures of about 80 degrees is what it takes to get hurricanes and tropical systems going. The current (surface) ocean temperatures are above average for spring and that trend is expected to last into the summer. 

"A very warm Atlantic favors an above-average season, since a hurricane’s fuel source is warm ocean water. In addition, a warm Atlantic leads to lower atmospheric pressure and a more unstable atmosphere. Both conditions favor hurricanes," experts at CSU wrote.

Wind sheer is a change in wind speed or direction with height.  Imagine someone wildly flapping their arms around as a figurative example of wind sheer.  Newsflash: hurricanes don't like wind sheer. It disrupts their ability to form.   

By the time we get to peak hurricane season — typically August, September and October — there may not be much wind sheer around. 

We are forecasted to be in a La Nina weather pattern, which favors higher hurricane activity due to the lack of wind sheer. 

Will all of the predicted storms make landfall?

Not all of the named storms will make landfall.  Some will stay at sea and not make landfall, but could send big waves ashore. 

What does this mean for me?

If you live along the coasts or even here in the Mid-Atlantic where the remnants of storms often pass, just be prepared to protect yourself and your property. This means if you hear of any type of tropical storm or hurricane watch or warning, have a plan to either evacuate or safely ride out the storm if it's possible.  

What about climate change?

Research suggest that climate isn't necessarily causing more hurricanes, but rather stronger hurricanes.  Research from the Geophysical Fluid Dynamics Laboratory, a division of NOAA, found that hurricanes may produce higher rainfall rates.  More rain, means more intense flooding.   Expert analysis found that with sea level rise, storm surge could be more intense. We could also see more intense hurricanes, those of category 3 and above.
