What to Expect From the Unusually Divided Global Hurricane Season
This year, we are looking at a deeply divided global setup. While the Atlantic is currently hitting the snooze button, the Pacific Ocean is working overtime. Let’s break down the meteorological mechanics driving this year’s forecasts, the hidden ocean patterns at play, and what it all means for coastal communities worldwide.
The Atlantic Basin: Dust, Cool Water, and a Stifled Start
If you’ve looked at a satellite feed of the Atlantic recently, you might have noticed that the tropics look surprisingly quiet. There are a few major atmospheric handbrakes currently suppressing the development of early-season tropical activity.
First, we have to talk about the Saharan Air Layer (SAL). Right now, massive plumes of Saharan dust are making their multi-thousand-mile trek across the Atlantic Ocean, drifting into the Caribbean and the Gulf of Mexico. Forecasts indicate this dust will eventually spread into the U.S. Southeast and parts of the Southern Plains.
While a little dust might just mean you have to wash your car more often—or enjoy exceptionally vibrant, hazy sunrises and sunsets—it is absolute kryptonite for developing tropical cyclones. The hot, dry air of the SAL acts like a giant atmospheric desiccant, sucking up the moisture that storms need to thrive. It creates a highly stable atmosphere, putting a lid on the Main Development Region (MDR) of the Atlantic.
Furthermore, the dust particles actually reflect incoming solar radiation back into space. This, combined with broader climate patterns, means that sea surface temperatures (SSTs) across the central and eastern MDR are currently running noticeably cooler than the record-breaking warmth we’ve seen in recent years. Cool water and dry air mean the Atlantic’s engine simply won't start.
The El Niño Factor
Beyond the dust, a developing El Niño in the equatorial Pacific is acting as the ultimate bodyguard for the Atlantic coast. Expected to strengthen right through the peak of the hurricane season, El Niño dramatically alters global wind patterns.
When El Niño warms the Pacific, it shifts thunderstorm activity eastward. This shift sends strong upper-level winds tearing across Central America and into the Atlantic Basin. This phenomenon, known as wind shear, effectively decapitates developing tropical systems, tearing their thunderstorm tops away from their low-pressure centers before they can organize.
Because of these competing factors—cool Atlantic waters, Saharan dust, and high wind shear—major forecasting agencies, including NOAA and Colorado State University (CSU), are currently predicting a below-normal Atlantic hurricane season.
The East Pacific: Waking Up Early
While the Atlantic is suppressed, the East Pacific hurricane season is officially off to an active start. Unlike the Atlantic, ocean temperatures near Mexico and stretching westward into the open Pacific are running 2 to 3 degrees above average. That warm water is high-octane fuel for tropical cyclones.
The National Hurricane Center (NHC) is currently monitoring two distinct areas of potential development:
- System One: Hovering off the coast of Mexico, this disturbance currently has a low 20% chance of development over the next seven days. However, long-range computer forecast models suggest it will eventually organize. Even if it remains just offshore as a tropical depression or named storm, it threatens to bring significant, potentially dangerous rainfall to coastal Mexican communities.
- System Two: Located much further out over the open waters of the East Pacific, this system has an 80% chance of development. Models show it organizing rapidly over warmer waters by mid-week. Fortunately, it is expected to stay well offshore, posing zero threat to land. As it eventually moves over cooler waters and encounters stronger upper-level winds, it will naturally spin down.
To put this in perspective, an average East Pacific season produces 15 named storms, eight hurricanes, and four major hurricanes. With El Niño historically supercharging this basin by reducing local wind shear, we could easily see those averages tested or exceeded this year.
The West Pacific: The Engine of Global Cyclones
If you want to see where the real atmospheric heavyweights are born, you have to look at the West Pacific. This basin doesn't really have an "off" season, and it typically churns out a staggering 26 named storms, 16 typhoons, and nine major typhoons annually.
Right now, meteorologists are closely tracking Typhoon Jangmi. Having strengthened into a typhoon over the weekend, the storm is currently churning a few hundred miles west of Guam. Thanks to a dangerous combination of low wind shear and incredibly warm ocean temperatures, Jangmi is expected to steadily organize as it pushes northwest.
The forecast track has Jangmi bringing hurricane-force winds and torrential rainfall to Japan's Ryukyu Islands. By Tuesday, the system will likely begin impacting mainland Japan—including major population centers like Osaka, Hamamatsu, and Tokyo. While Jangmi is expected to be weakening by the time it reaches Tokyo, it could still unleash wind gusts exceeding 50 mph and cause significant localized flooding.
Jangmi is just the latest in an already aggressive season. It follows on the heels of April’s Super Typhoon Sinlaku, a monster storm that rapidly intensified to pack winds of 175 mph. Sinlaku caused extensive devastation across the Northern Mariana Islands and Guam, cementing its place as one of the strongest early-season typhoons ever observed. With El Niño intensifying, the West Pacific is primed to remain highly active.
The Legacy of Storms: Naming and Retiring
When we talk about these massive weather events, it’s easy to get lost in the meteorology and forget the human impact.
Just seven months ago, Hurricane Melissa slammed into Jamaica, bringing catastrophic wind gusts of up to 250 mph to the island. From Montego Bay to Black River—where the storm made its devastating landfall—communities are still in the throes of a long, arduous recovery process. The start of the 2026 season has understandably put these rebuilding communities on high alert.
Because of the sheer death and destruction caused by the storm in October 2025, the World Meteorological Organization (WMO) Hurricane Committee made a unanimous decision: the name "Melissa" has been officially retired. There will never be another Hurricane Melissa.
This brings up a fascinating aspect of how we categorize these storms. The names used for hurricanes in the Atlantic and Eastern Pacific rotate on a strict six-year cycle.
Here are a few quick facts on how the naming convention works:
- Alphabetical Order: Storms are named in alphabetical order, starting with "A" each season.
- The Lists: There are 21 names allocated for the Atlantic season list and 24 names for the Eastern Pacific list.
- Recycling: Because the lists operate on a six-year cycle, the names you saw in 2020 (the ones that weren't retired) are the exact same names being used right now in 2026.
- Retirement: As the NHC notes, a hurricane name is retired permanently if a storm is so deadly or costly that using its name again would be inappropriate and insensitive to the survivors.
As we push deeper into the 2026 season, the divided nature of the world's oceans serves as a powerful reminder of how interconnected our global climate system truly is. Saharan dust in Africa protects the shores of Florida, while shifting waters in the Pacific threaten the coastlines of Mexico and Japan. Regardless of what the seasonal forecasts say, it only takes one storm making landfall to make it an active season for you.
