Scientists report that the Pacific hurricane region has set a record for persistent and powerful storms, driven by El Niño conditions and warm ocean waters. Since September 20th, this area east of the international date line, which affects Hawaii, Mexico, and parts of the U.S., surpassed its previous ACE (accumulated cyclone energy) record from 2018. The favorable climate pattern weakens wind shear in the Pacific while intensifying it in the Atlantic, promoting storm development in one basin while inhibiting it in the other. Researchers attribute the unusually active hurricane season to both El Niño and long-term global warming trends.

The drumbeat of monster hurricanes in the Pacific has broken a record for nasty long-lasting storms east of the international date line, turbocharged by nature’s supersized El Niño, scientists said.
asserted
scientists → break → Niño
“Since September 20th, when Odalys formed, it’s been berserk,” said Colorado State University researcher Phil Klotzbach, who forecasts and studies storm activity.
asserted
who → form → activity
“This year just everything that forms is just lasting a long time and getting really powerful.”
asserted
that → form → ?
One of the key measurements meteorologists use to judge hurricane seasons is called accumulated cyclone energy, or ACE, which includes a storm’s wind speed and longevity.
asserted
which → use → speed
On Sunday, a section of the Pacific east of the date line, which brews storms headed for Hawaii, Mexico and the U.S. West Coast, passed the old mark set in 2018.
asserted
which → brew → 2018
The area is still going strong with Hurricane Simon and appears on the verge of spawning another one that will really ramp up in strength, Klotzbach said.
asserted
Klotzbach → go → strength
On Tuesday, the Pacific will tie a record for most days with a hurricane spinning and is likely to break it soon after that, Klotzbach said.
“It feels like almost everything that can spin up does spin up,” said University of Arizona atmospheric scientist Kim Wood.
asserted
Wood → tie → Arizona
El Niño and warm water are boosting Pacific hurricanes
asserted
Niño → boost → hurricanes
Several meteorological factors have come together to supercharge the Pacific, chief among them the El Niño, Klotzbach and other hurricane researchers said.
asserted
Klotzbach → come → them
An El Niño weakens and shifts the high altitude vertical winds that otherwise can dampen or even decapitate storms.
asserted
that → weaken → storms
In the Pacific, that wind shear runs east to west, generally with the direction storms travel, so it’s like riding a bicycle with a tail wind, Klotzbach said.
asserted
Klotzbach → run → wind
Meanwhile, the weather pattern has dampened hurricanes in the Atlantic, where the ACE is less than 18% of what’s normal for this time of year.
asserted
what → dampen → year
El Niño makes the wind shear in the Atlantic like riding into a headwind, he said.
asserted
he → make → headwind
Another factor is warm water, which serves as hurricane fuel.
asserted
which → serve → fuel
By definition El Niño is a warming of the equatorial Pacific that changes weather worldwide.
asserted
that → change → weather
In the Pacific storm basin, it’s several degrees Fahrenheit warmer than normal, said University at Albany storm atmospheric sciences professor Kristen Corbosiero.
asserted
Corbosiero → ’ → Albany
Usually in the Pacific, the extra warm storm-friendly water doesn’t run as deep as it does in the Atlantic.
asserted
it → run → Atlantic
So when one storm goes over a patch of water, it brings up cold water and makes it hard for a subsequent storm in the same area to stay alive, Wood said.
asserted
Wood → go → area
Hurricane Rachel, whose remnants swamped Las Vegas over the weekend, didn’t suffer as it went over, churned up by Category 5 Hurricane Polo, Wood said.
asserted
Wood → swamp → Polo
She said the waters are warm from both El Niño and climate change from the burning of coal, oil and gas.
asserted
waters → say → coal
Another factor in recent storms was a counterclockwise atmosphere spin over Central America — called a gyre — that spits out seeds of stormy weather that can form into hurricanes.
asserted
that → call → hurricanes
It spit out both the Atlantic’s Isaias and the Pacific’s Simon at about the same time, Corbosiero and Klotzbach said.
asserted
Corbosiero → spit → time
The last five Pacific hurricanes — long-lasting Nolo, Odalys, Polo, Rachel and Simon — have all reached major status with winds of at least 111 mph (178.6 kph).
asserted
hurricanes → last → mph
Nolo, Odalys and Simon hit Category 4, while Polo set the record for time spent at Category 5 at two-and-a-half days.
asserted
Polo → hit → days
When Klotzbach made those calculations on the record-breaking activity of the eastern and central Pacific, he looked at all storms east of the date line.
asserted
he → make → line
That’s a slightly different approach from the National Oceanic and Atmospheric Administration, which breaks that broad area into two regions.
asserted
which → ’ → regions
Neither NOAA-defined region is quite at record levels for ACE yet; put together they are.
asserted
they → define → ACE
Part of that is because often when one of those subregions is more active, the other isn’t quite as crazy, but in 2026 they both are hyperactive, Wood said.
asserted
Wood → say → 2026
“This is the first year that both sides have been this active together,” Wood said.
asserted
Wood → say → ?
“Usually it’s kind of focused more on one or the other, so that speaks to just the wide extent across this region of where there’s been that lower shear, those warmer waters, and that higher moisture.
asserted
shear → focus → region
Off the Mexican coast is a disturbance that the National Hurricane Center gives a 90% chance of becoming Tropical Storm Trudy, which then could power up to something big, Klotzbach and Corbosiero said.
uncertain
Klotzbach → give → something
“It seems like that area is just one after another.
asserted
area → seem → another
So I would not be surprised to have another storm,” Corbosiero said.
asserted
Corbosiero → have → storm
“This year, because of the El Niño, we do have very favorable conditions.
asserted
we → have → conditions
So as long as there’s some sort of the seeds either from the gyre or from remnant ends of cold fronts, it seems like this is going to continue for a bit.”
asserted
this → ’ → bit
