Meteorologist Jonathan Kegges says the 2026 Atlantic hurricane season could get off to a faster start than usual, not because of a single dramatic computer model run, but because several large-scale atmospheric signals are lining up in a way that deserves attention.
In his recent forecast on the JustWeather channel, Kegges focused on the western Caribbean, the eastern Gulf of Mexico, and the far southwestern Atlantic as the area to watch near the opening days of hurricane season, which officially begins June 1 on the Atlantic side.
He was careful not to frame the setup as a guaranteed storm, and that matters. Long-range tropical forecasting is full of uncertainty, especially more than two weeks out, but Kegges said the atmosphere is showing a consistent signal for rising motion, lower wind shear, warm water, and increased tropical moisture in the same general region.
At minimum, he said, that could mean a surge of thunderstorms and tropical moisture into the southeastern United States. If the ingredients come together more cleanly, however, it could also allow something more organized to form during the first week of June, give or take a few days.
A Signal Near The Start Of Hurricane Season
Kegges said the area he is watching stretches from the western Caribbean into the eastern Gulf and toward the extreme southwestern Atlantic, a zone that often becomes important when early-season tropical moisture begins lifting north.
The timing he highlighted centers around the end of May into early June, especially the May 27 to June 3 period, when long-range guidance shows a strong rainfall anomaly developing near the western Caribbean and eastern Gulf. In some locations, he said the forecast signal suggests rainfall could run four to six inches above normal.
That does not mean a tropical storm is already on the map, and Kegges repeatedly stressed that specific dates, tracks, and strength cannot be pinned down this far in advance. What forecasters can watch, though, is whether the broader environment becomes favorable for tropical development.
That broader environment is the reason this forecast stands out.
Kegges said the first ingredient he looks for is whether the atmosphere has a forcing mechanism that can lift air, increase thunderstorms, and help organize disturbed weather. In this case, he pointed to a strong signal for rising air moving from the eastern Pacific toward the western Caribbean and eastern Gulf as the calendar flips into June.
In simpler terms, the atmosphere may be preparing to create more showers and storms in the exact region where early-season systems sometimes try to form.
The Pancake Problem With Wind Shear
After lift, Kegges turned to wind shear, one of the most important obstacles for tropical development.
He described tropical systems as needing to stack vertically, “like a stack of pancakes,” with thunderstorms rising more or less straight up. When wind shear is strong, winds change speed or direction with height and tilt the storm structure, causing those “pancakes” to slide apart.
That kind of setup can rip developing tropical systems apart before they ever become organized.
For the first week of June, however, Kegges said the forecast shows a broad area of below-normal wind shear in the same region where rainfall and rising air signals are showing up. He noted that wind shear is often lower as May transitions into June anyway, but the signal he showed was still notable because it overlapped with the western Caribbean and eastern Gulf moisture surge.
That overlap is what makes the pattern worth monitoring.
A rainy disturbance in a hostile environment is usually just that – a rainy disturbance. But a disturbance moving into warm water with low wind shear has a better chance to organize, especially if the atmosphere is already encouraging thunderstorms to grow.
Warm Water Is Already In Place
Kegges said the water temperatures are another reason forecasters cannot ignore the setup.
Tropical systems generally need water temperatures around 80 degrees Fahrenheit or warmer to develop and strengthen, and Kegges said the western Caribbean and eastern Gulf are already plenty warm.
He pointed to sea surface temperature anomalies running roughly two to six degrees Fahrenheit above normal in some of the areas being watched. Actual water temperatures in parts of the eastern Gulf are already in the 80-to-85-degree range, which is warm enough to support tropical development if other atmospheric ingredients cooperate.
That does not automatically mean a storm will form, but it does remove one of the main limiting factors.
Early June systems can sometimes struggle because the atmosphere is not fully ready, or because wind shear is still too strong, or because water temperatures are marginal in some regions. In this case, Kegges said the water temperature box is already checked in the region where the signal is strongest.
This is where the forecast becomes less about one model showing one suspicious low-pressure area and more about multiple background factors pointing in the same direction.
The Model Hint Is Not The Whole Story
Kegges did show a European model signal for lower surface pressure near the western Caribbean and Gulf around June 3 and June 4, but he was quick to say that the model itself is not the main reason for the forecast.
He said he does not like hype and was not trying to hype the possibility of a storm. That distinction is important because long-range tropical model maps often get shared online as if they are finished forecasts, when in reality they are better viewed as clues.
Kegges said the model hint is more like the “cherry on top” of a larger atmospheric signal. The stronger point, in his view, is that the broader environment appears to support a surge of tropical moisture, enhanced thunderstorm activity, and possibly some kind of organization near the start of the season.
He also said this is different from simply chasing every long-range model storm that appears in May. On the JustWeather channel, he said he had already pushed back on a previous mid-May signal that did not look legitimate.
This one, he argued, has more support because the background pattern is more consistent.
That is a useful approach for viewers because the early season always brings a wave of speculation, especially when a model paints a low-pressure swirl somewhere near the Gulf. Kegges’ point was not that people should panic, but that they should understand why forecasters are watching the first week of June more closely than usual.
Rain Could Help A Dry Southeast
If something does develop, Kegges said not every outcome would be bad, provided any system remains on the weaker side.
He pointed to drought conditions across Florida and parts of the southeastern United States, including exceptional drought in Florida’s Big Bend region into southeast Georgia and parts of South Carolina, along with extreme drought in other areas including parts of southwest Florida.
A weaker tropical system or broad tropical moisture surge could bring much-needed rain to those areas.
That is the complicated part of early-season tropical weather. A strong storm is obviously dangerous, especially if it brings flooding, surge, or damaging winds, but a disorganized or low-end system can sometimes deliver beneficial rain to places that badly need it.
Kegges made that caveat clear. The region could use rainfall, but the goal would be moisture without a damaging storm attached to it.
For Florida and the Southeast, this means the first week of June may be worth watching not only for tropical development, but also for the possibility of a meaningful shift in the moisture pattern after a dry stretch.
The Pacific May Move First
Kegges also noted that the eastern Pacific may see tropical development before the Atlantic side does.
He pointed to an official Climate Prediction Center highlight showing a greater than 40% chance of tropical development in the eastern Pacific from May 27 through June 2. That region appears to be where the Madden-Julian Oscillation, or MJO, forcing moves first.
The MJO is a large-scale tropical disturbance that can help enhance thunderstorm activity as it travels around the globe. When it moves into the right region at the right time, it can increase the odds of tropical development by providing the lift and thunderstorm support that developing systems need.
Kegges said the key question is whether that same forcing then shifts from the eastern Pacific into the Atlantic basin during the first week of June.
If it does, the western Caribbean and Gulf could become more active right as the Atlantic hurricane season officially begins.
That does not guarantee a named storm, but it does suggest the season may not start quietly.
Kegges said he still expects the broader year may turn quieter for long stretches, something he plans to explain in an updated hurricane season outlook. Still, the opening days of June may carry their own separate risk if the current signal holds.
For now, the takeaway is measured but clear: the atmosphere is showing enough consistency that residents along the Gulf Coast, Florida, and the Southeast should begin paying attention as the calendar approaches June.
This is not the moment to panic over a single model run, but it is the moment to remember that hurricane season can begin quickly when the ingredients arrive together.
