Tracking hurricane patterns: Why do hurricane tracks shift throughout the season?

The Northeast Florida & Southeast Georgia area tends to see the greatest tropical system impacts in September, October

With this Saharan dust suppressing the tropics for a moment, it’s a good time to talk about why hurricane tracks differ throughout the hurricane season.

During the Atlantic Hurricane Season, hurricane tracks change monthly, generally following the same pattern year after year.

That means certain areas in the tropics tend to see a higher number of storms during certain parts of the season.

Throughout July, hurricanes tend to track into the Gulf and Caribbean, but as the season progresses, those tracks tend to move eastward into the Eastern Gulf and the Atlantic.

Hurricane Beryl, the first hurricane of the 2024 season, began its formation in the Eastern Atlantic but tracked south toward the Caribbean and curved into the Yucatan Peninsula, ultimately making landfall in Texas as a Category 1 hurricane.

So, why did Beryl take this particular track and not head toward the Sunshine State?

Well, the short answer is steering flow.

You’ve heard The Weather Authority say it many times: Warm water favors thunderstorm organization.

But because the Atlantic is larger and deeper than the Gulf, more energy is needed to heat the Atlantic.

So during this time of the year, it’s likely to see the majority of hurricane tracks in the Caribbean and Gulf, where waters are warmer.

In the later parts of the season, when the Atlantic is warmer, you start to see tracks shift toward the eastern Atlantic.

That’s why our area tends to see its strongest hurricane impacts in September and October.

But once a storm system organizes into a tropical cyclone what moves it along?

The Bermuda High plays a huge role in steering these storms westward.

A stronger Bermuda High leads to hurricanes that push further west before they curve north.

When the ridge is weak, gaps may develop, allowing systems to track northward in the Atlantic.

Now, because water temperatures are abnormally high for this time of the year, and with the help of a La Niña phase, the National Weather Service has predicted an abnormally high number of named storms for this season.
