A developing low-pressure system over the Northeast Pacific is forecast to direct a strong atmospheric river (AR) toward California between November 12 and 15, 2025. The Center for Western Weather and Water Extremes (CW3E) indicates a high probability of moderate to strong AR conditions in Northern and Central California, with heavy precipitation possible in the Sierra Nevada and coastal ranges.
A powerful tornado struck the municipality of Rio Bonito do Iguaçu, Paraná, southern Brazil, in the late afternoon of November 7, 2025, killing at least five people and injuring over 130, of whom 30 were seriously injured. Winds exceeding 240 km/h (150 mph) destroyed most of the town’s structures, prompting a large-scale emergency response by Civil Defense, the Fire Department, and state authorities.
Solar activity reached high levels on November 5, 2025, as Region 4274 (N24E40) produced two powerful M-class flares – an M7.4 at 11:19 UTC and an M8.6 at 22:07 UTC. The full-halo CME from the first event is expected to reach Earth late November 6 to early November 7, likely producing G3 – Strong geomagnetic storm conditions and visible auroras across Canada and the northern United States.
A G3 – Strong geomagnetic storm is forecast for November 6 and 7, 2025. The disturbance originates from X-class solar flares and associated coronal mass ejections (CMEs) recorded on November 4, combined with a coronal-hole high-speed stream. Aurora is expected to become visible across much of Canada and the northern United States, possibly reaching as far south as Pennsylvania, Iowa, and Oregon.
Two powerful X-class solar flares erupted on November 4, 2025 — an X1.8 from Region 4274 and an X1.1 from a region just beyond the east limb — launching CMEs largely off the solar limb. NOAA forecasts G1 – Minor to G2 – Moderate geomagnetic storming from late November 6 into 7 as Earth may experience a glancing shock from the flares combined with a coronal hole high-speed stream.
A major solar flare measuring X1.8 erupted from Active Region 4274 at 17:34 UTC on November 4, 2025. The event started at 17:15 and ended at 17:51 UTC. This is the first X-class flare since the impulsive X1.9 from Active Region 4114 at 23:50 UTC on June 19, 2025.
Minor ash emissions were confirmed at Whakaari / White Island, New Zealand, following two short-lived eruptions on October 30, 2025. The Volcanic Alert Level remains at 3 and the Aviation Color Code at Orange, indicating minor eruptive activity with uncertain future development. An observation flight on November 3 confirmed an ash plume rising 400–500 m (1 300–1 600 feet) above sea level, drifting southeast for 5–8 km (3–5 miles).
A newly discovered asteroid designated 2025 UC11 flew past Earth at a distance of 0.017 lunar distances (0.00004 AU / 6 599 km / 4 101 miles) at 12:11 UTC on October 30, 2025. The object was first detected seven hours earlier by the JPL SynTrack Robotic Telescope in Auberry, California.
A long-duration solar flare measuring M5.0 erupted from an active region located at the NE limb of the Sun at 10:11 UTC on November 3, 2025. The event started at 09:38 and ended at 10:37 UTC.
A strong and shallow earthquake registered by the USGS as M6.3 struck central Afghanistan at 20:28 UTC on November 2 (00:58 local time, November 3), 2025. The agency is reporting a depth of 28 km (17.4 miles). EMSC is reporting the same magnitude at a depth of 10 km (6.2 miles).
