This post synthesizes the latest forecasts for an unusually active 2026 Atlantic hurricane season and accompanying U.S. and Pacific weather hazards. Drawing on assessments from the University of Arizona and NOAA, it outlines the driving factors, regional risk hot spots, and practical steps communities can take to reduce impacts as the season unfolds.
Forecast and drivers for the 2026 Atlantic hurricane season
Current analyses indicate an above-average Atlantic hurricane season is likely, driven in large part by persistently warm sea surface temperatures. There is also a credible chance that a strong El Niño could develop and endure through the summer into the peak of the hurricane season.
This would influence storm patterns and intensity. In addition, record warmth is expected to shift eastward, increasing rainfall and storm activity across major U.S. cities.
Key climatic factors driving elevated risk
- High Atlantic sea surface temperatures that fuel the formation and intensification of tropical cyclones.
- Potential El Niño development that can modify storm tracks and moisture distribution across North America.
- Shifts in warmth patterns that may lead to more persistent rain in urban centers and a lingering storm footprint.
Regional risk highlights across the U.S.
With multi-system weather on the horizon, several regions face distinct hazards. These range from severe convective storms in the Southern Plains to heavy rainfall and flooding risks in Hawaii and the Pacific.
A broad pattern of active weather is anticipated to affect infrastructure, air quality, and daily life in many communities.
Southern Plains and Hawaii: Severe storms and flooding threats
The Southern Plains are expected to contend with a heightened risk of damaging winds, large hail, and tornadoes as meteorological conditions evolve. Hawaii, meanwhile, is dealing with repeated heavy rainfall and flash flood concerns after a third Kona Low in a single month drenched the islands.
- Near-term convective outbreaks capable of widespread wind and hail damage.
- Urban flash flood risk in Hawaii associated with persistent rainfall events.
Pacific and West Coast weather patterns
Across the Pacific and western United States, a dramatic and layered weather scenario is unfolding. A powerful typhoon is intensifying in the western Pacific and is forecast to impact Guam.
The West Coast could experience heavy rainfall and even feet of mountain snow as storm systems sweep through the region. A sprawling 1,000-mile storm system is anticipated to prolong severe weather threats across broad areas, amplifying risk to transportation, power, and water resources.
Sinlaku, Guam, and West Coast snow risk
Typhoon Sinlaku has strengthened and is projected to threaten Guam, prompting local meteorologists to prepare for a rare and potentially violent tropical cyclone. Separately, the West Coast faces multiple storms that could deliver substantial rainfall and substantial snowmelt in mountainous terrain.
Some forecasts indicate several inches to feet of snow in high elevations.
- Guam could see direct impacts from a powerful tropical cyclone, necessitating readiness across communities and infrastructure.
- Mountain snow on the West Coast may interact with rainfall to change flood risk and travel conditions.
Urban air quality, wildfires, and overlapping hazards
Across the United States, communities confront overlapping hazards—tropical risks, severe storms, floods, mountain snow, and wildfire smoke. One notable example occurred near Philadelphia, where wildfire-driven smoke affected airport operations.
This illustrates how localized events can compound regional weather risks.
Preparedness and response for communities
Effective planning now can mitigate disruption as multiple hazard streams converge.
Local authorities, emergency managers, and residents should reinforce communication channels, prepare emergency kits, and review evacuation and shelter-in-place protocols in vulnerable areas.
- Monitor forecasts from trusted meteorological agencies and heed official advisories during severe weather outbreaks.
- Prepare for rapid changes in conditions—from heavy rain and floods to high winds and snowfall in mountains.
- Limit exposure to wildfire smoke by staying indoors with filtration when air quality is poor and using masks when outdoor exposure is unavoidable.
