2024 hurricane season brings new risks: WESH long-range forecast reveals crucial 'hot spots' for Florida
The 2024 Atlantic hurricane season is right around the corner, which is why for the last few months I've been working on my own hurricane seasonal forecast. This isn't your standard "X" number of storms style forecast- this is looking at weather patterns to give you an idea of "hot spots" for the season, along with "hot dates" on the calendar, so you can have an idea what the season will look like.
Before we look ahead, let's look at how we did last year. In 2023, our forecast accurately predicted where every named storm went, and when they made landfall. Curious how it looked? Here is last years hotspots with actual storm tracks:
So- how do we look this year?
2024 Hot Spots
What areas are at the greatest risk of seeing a landfalling tropical system in 2024? I have identified a couple of hot spots along the U.S. coast that have a higher than average chance of being directly impacted this hurricane season.
The main thing you should notice, is that THIS year Gulf coastlines are looking at above average threats- a big shift from the last few years. I also want to mention the pattern flows-
Clearly ALL pointing to the eastern Gulf coast. This is particularly concerning for us Floridians, as it tells me that not only are we under a higher threat for tropical impact, but perhaps the greatest threat I've forecast since beginning these long range outlooks years ago.
Now that we've outlined the overall pattern, let's start looking at things storm by storm. We can begin by looking at the part of the pattern most concerning to me- the South Florida part of the pattern.
SOUTH FLORIDA STORM
First spotted in November, this part of the pattern has repeated over and over, showing a clear threat for South Florida, particularly SW Florida.
Potential return dates for this part of the pattern include May 23-28, July 9-15, and August 26-September 1
Gulf to Carolinas Low
First spotted around Halloween 2023- this part of our weather pattern showed a storm system crossing through the big bend... through Florida... and then up to the Carolina coastline. I've observed this weather cycle over and over again- and think it's a key part of our 2024 weather pattern.
Potential return dates for this part of the pattern include June 24-29, August 10-16, and September 26-October 3.
Gulf Coast Low
First spotted October 11th, and observed several times through- this low formed over the gulf waters, and then started working more eastward. The overall large geographical area of this is because of its observed motion each time, moving east along the Gulf coast.
Potential return dates for this part of the pattern include June 6-10, July 23-28, and September 8-14.
Number Of Storms
For this year's forecast, we looked deep into the El Nino/La Nina switchover. We're coming off a quick but strong El Nino pattern- shifting to La Nina this late summer-fall. In the five examples we studied in past years (1966, 1973, 1983, 1998, and 2016), there was a clear signal in the overall numbers. For these example years, the number of named storms came down a bit- but there was a greater percentage of storms intensifying into hurricanes and even major hurricanes. Perhaps the idea there to take away is that things that form could get stronger this year, more-so than 'normal' conditions.
How is this forecast even possible?
As crazy as it sounds, there are many elements that play a role in our forecast puzzle. From sea surface temperatures, to La Niña, and fancy weather terms like 'AO' and 'NAO' you get pieces to the puzzle, BUT, the main thing that helps clear this up and look long range is the LRC.
The LRC, or Lezak's Recurring Cycle (named for the meteorologist who discovered it) is a technique that uses the past to predict the future. The term "what goes around comes around" isn't just for life, Lezak discovered this could be applied for weather as well. Before we get into the forecast, let me explain how this all works:
The basics of the LRC
- A unique weather pattern sets up each fall and becomes established.
- Long-term repeating features are clues to where storm systems will reach peak strength, and where they will be their weakest.
- Once the weather pattern is set it cycles, repeats, and continues through winter, spring, and summer.
The key to this forecast and using the cycling weather technique is by determining the cycle duration. It ranges year to year from 40-70 days- but once you key in on it, you can forecast the weather through the end of the "LRC year," or about the start of October. This means while it's a great tool, the limitation is that by October 2023 we start setting up a new "LRC year," thus the very end of hurricane season can't be predicted this early.
Final Thoughts
First and foremost going into any hurricane season, we need to be prepared. Take the time now to be sure your family has a plan in place and a hurricane kit ready to go if a tropical system were to threaten our local area.
One question that usually arises is locations outside of the hot spots discussed. These areas still could see tropical activity/landfall this season, but the chances are much closer to average or even below average. An example based on the pattern we identified would be the Texas coast- where chances are average to below average of a landfall this season. In contrast, the gulf coast/Florida west coast is in a hot spot. This length of the Florida coast has an above average chance of a tropical system(s) making landfall during the 2024 hurricane season.
These weather patterns represent to me the disturbances with the most potential to produce tropical activity. It's important to keep in mind they are NOT the only features that could produce a tropical systems for the year. Add that the NEW 2024-2025 cycle establishes in October so things will look very different for October and November.
