The 2026 Eastern Pacific hurricane season is barely a week old, and forecasters are already watching a patch of disturbed weather that could become the basin’s first organized tropical system. The National Hurricane Center flagged the disturbance in its evening outlook on May 20, noting that conditions across the basin bear monitoring as convection flares south of Mexico’s Pacific coast.
Meanwhile, the Atlantic basin is silent. The NHC’s same-day Atlantic outlook lists no areas of concern, and the agency’s year-to-date tally shows exactly what you’d expect for mid-May: zero named storms, zero hurricanes, zero major hurricanes. That quiet is about to get an official frame. NOAA is set to release its full 2026 Atlantic seasonal outlook in the coming days, and the climate signals shaping it point toward a subdued summer in that basin.
The reason for the split personality between the two oceans comes down to three letters: El Niño.
El Niño is tilting the scales
NOAA’s Climate Prediction Center reports that El Niño conditions are in place and expected to persist well into the heart of hurricane season. El Niño warms sea surface temperatures across the central and eastern equatorial Pacific, and that warmth reshapes atmospheric patterns thousands of miles away.
Over the tropical Atlantic, El Niño ramps up vertical wind shear, the change in wind speed and direction with altitude that tears apart developing storms before they can organize. Over the Eastern Pacific, the opposite happens: shear drops, instability rises, and the atmosphere becomes more hospitable to tropical cyclones.
History backs this up. During moderate-to-strong El Niño years, the Atlantic has consistently produced fewer named storms and lower Accumulated Cyclone Energy totals compared to the long-term median, while the Eastern Pacific has tended to run above average. The pattern is not a guarantee for any single storm, but it is one of the strongest seasonal predictors meteorologists have.
What we know about the Eastern Pacific disturbance
The NHC’s Eastern Pacific Tropical Weather Outlook identifies an area of disturbed weather but stops short of assigning high formation probabilities in its written discussion. That language is deliberate: it tells forecasters and the public that the environment is worth watching without signaling imminent development.
Key details remain unresolved. The outlook does not yet describe the disturbance’s precise location in granular terms, its movement, or the steering currents that will determine whether it drifts harmlessly westward into open ocean or curves toward the coastlines of Mexico, Baja California, or, less commonly, Hawaii. Early-season Eastern Pacific systems can go either way. Some fizzle within days; others intensify rapidly when they tap warm water and low shear simultaneously.
The NHC’s graphical outlook maps, which assign 48-hour and seven-day formation probabilities, update on their own cycle and may contain more specific numbers than the text product. Residents along Mexico’s Pacific coast and mariners operating offshore should check both products regularly as the disturbance evolves.
The Atlantic: quiet now, but context matters
The Atlantic Tropical Weather Outlook issued on May 20 is clean: no areas of interest, no formation chances, no advisories. The official Atlantic season does not begin until June 1, so the empty board is routine, not remarkable.
What will matter more is the content of NOAA’s seasonal outlook, typically released in late May. That product will translate the current El Niño signal, along with Atlantic sea surface temperatures, African easterly wave activity, and other large-scale drivers, into projected ranges for named storms, hurricanes, and major hurricanes. Until that outlook is published, specific claims about how far below normal the Atlantic season might fall are speculation, not science.
And even a below-average season is not a safe season. The 2014 Atlantic season produced only eight named storms during El Niño conditions, but Hurricane Arthur still made landfall in North Carolina on July 4. It takes only one well-placed storm to turn a statistically quiet year into a personally devastating one.
What residents on both coasts should do right now
For communities along Mexico’s Pacific shoreline, Central America, Hawaii, and the U.S. West Coast, the Eastern Pacific season is not a future event. It is happening. The NHC’s full suite of operational products, including formation-probability maps, satellite overlays, and advisory archives, is live at nhc.noaa.gov. Now is the time to confirm evacuation routes, restock emergency kits, and make sure family communication plans are current. Boat owners and coastal businesses should review storm protocols before watches are posted, not after.
Along the Atlantic and Gulf coasts, the pre-season window is a gift, not a pass. With less than two weeks before June 1, this is the moment to verify flood and wind insurance coverage, photograph property for potential claims, trim overhanging branches, and clear gutters and drains. These small steps cost little in calm weather and pay off enormously when a storm bears down.
Where to get reliable information as the season unfolds
Stick to primary sources. The NHC’s text and graphical outlooks are the authoritative word on tropical development in both basins. Local National Weather Service offices add regional detail, including storm surge forecasts and inland flooding risk, that the national products do not cover. Trusted local broadcast meteorologists and newspaper weather teams can translate those products into neighborhood-level guidance.
Social media amplifies rumors and exaggerated model runs faster than any hurricane moves. When a disturbance is on the map, as one is right now in the Eastern Pacific, the temptation to scroll through worst-case scenarios is real. Resist it. The best defense against both complacency and panic is the same: verified data, checked often, paired with a plan you have already rehearsed.
