A study of more than 8 million people found that heat waves trigger immediate increases in cardiovascular events, while cold waves produce delayed effects over several days. The analysis, covering 2011 to 2020, recorded significant increases in cardiovascular deaths and major adverse events under both temperature extremes.
Blue auroras could be possible over Arctic regions in late April 2026 as seasonal solar geometry allows sunlight to illuminate the upper atmosphere while ground-level skies remain sufficiently dark. The phenomenon is linked to ionized nitrogen emissions that are typically too faint to detect but can be amplified under these conditions.
More than 3 000 residents were ordered to evacuate in Otsuchi, Iwate Prefecture, Japan, by April 25, 2026, as two wildfires ignited on April 22 expanded across mountainous terrain and burned hundreds of hectares. Fire damage to structures has been confirmed as suppression efforts continue.
NOAA’s Storm Prediction Center placed parts of central and southeast Oklahoma under a Moderate Risk for severe thunderstorms on April 25, 2026, with large to very large hail, tornadoes, and damaging winds forecast across parts of the southern Plains and Ark-La-Tex. Hailstones over 7.6 cm (3 inches) and strong tornadoes are possible during the afternoon and evening, where discrete supercells develop.
A rare tornado event occurred in California after three tornadoes touched down in Fresno and Merced counties on April 21, 2026. This was the third time since 1955 that three or more tornadoes have touched down in the National Weather Service (NWS) Hanford Office’s jurisdiction.
Hundreds of wildfires continued burning across southern Georgia on April 22, 2026, prompting authorities to place 91 counties under a State of Emergency for at least 30 days. The fires have burned more than 14 160 ha (35 000 acres) this month, destroyed dozens of structures, and forced evacuations as drought conditions persist.
Amtrak partially suspended rail operations in Florida on April 20, 2026, due to wildfires in Putnam and Clay counties, which have burned approximately 1 093 – 1 214 ha (2 700 – 3 000 acres). Passenger trains were halted as a precaution, including Train 98 from Miami to Jacksonville carrying 232 passengers.
Heavy snow and strong winds are forecast to impact the Sierra Nevada, California, from April 21 to April 22, 2026, as a Pacific storm system moves inland, bringing significant snowfall to elevations above 2 100 m (7 000 feet). Authorities warn that travel through major mountain passes could become very difficult to impossible due to snow-covered roads and reduced visibility.
Heavy snow, sleet, and freezing rain are unfolding across the Northern Plains and Upper Midwest on April 2, 2026, as a low-pressure system tracks northeast. A second winter storm is forecast to intensify from April 3–4, worsening the ongoing hazardous travel and increasing the risk of power outages across the Great Lakes region.
A late-season winter storm is forecast to impact the Upper Midwest and Great Lakes region from late April 1 through April 3, 2026, bringing widespread freezing rain, sleet, and snow across multiple states. Ice Storm Warnings, Winter Storm Warnings, Winter Weather Advisories, and Winter Storm Watches are in effect, with ice accumulations up to 10 mm (0.4 inches) and snowfall exceeding 45 cm (18 inches) in some areas, creating hazardous travel conditions and potential power outages.
