• Weak La Niña supports wet north-dry south pattern across the western U.S. through March 2026

    Experimental seasonal forecasts from the Center for Western Weather and Water Extremes (CW3E) suggest that a weak La Niña is reinforcing a wet–north, dry–south precipitation pattern across the western United States during January–March 2026. The outlook shows high-confidence signals for below-normal precipitation in Southern California, while model uncertainty remains higher across central and northern California.

  • Freeze warnings issued across Florida Panhandle and parts of the southeast U.S.

    Freeze warnings are in effect across the Florida Panhandle, northern and central counties, and parts of southeast Georgia from 23:00 EST Thursday, January 15, 2026, through 09:00 EST Friday, January 16. Temperatures are forecast to drop as low as −6°C (22°F) in inland areas, producing frost capable of damaging unprotected crops and causing water pipes to freeze and burst.

  • Red Flag Warning and High Wind Watches issued across central U.S. as strong northwesterly winds develop

    Strong northwesterly winds and very low humidity will bring critical fire weather conditions across eastern Colorado and western Kansas on Thursday, January 15, 2026, prompting the National Weather Service in Goodland to issue a Red Flag Warning and Fire Weather Watch. At the same time, high wind watches have been issued across the northern and central Great Plains, with gusts up to 120 km/h (75 mph) expected Thursday through Friday, January 16.

  • La Niña breakdown underway as models point to ENSO-neutral conditions in early 2026

    La Niña conditions in the equatorial Pacific show signs of a transition toward ENSO-neutral conditions, with potential for El Niño development later in 2026. Observations from the National Oceanic and Atmospheric Administration (NOAA) and the European Centre for Medium-Range Weather Forecasts (ECMWF) show subsurface ocean warming and westerly wind anomalies across the central Pacific, indicating the breakdown of the three-year La Niña phase.

  • Santa Ana winds bring damaging gusts up to 70 mph, elevate fire weather concerns across Southern California

    Strong Santa Ana winds intensified across Southern California on Friday, January 9, 2026, prompting the National Weather Service to issue high wind warnings and advisories for mountain, valley, and coastal regions. Gusts reaching up to 115 km/h (70 mph) were recorded in canyon and foothill areas, raising risks of power outages, tree damage, and hazardous travel conditions through the weekend.

  • Remnant Alaska atmospheric river to merge with second plume, bringing prolonged AR conditions to western Washington

    An atmospheric river that impacted Alaska on January 9, 2026, is forecast to propagate down the coast and merge with a second plume, delivering a 48–72-hour period of AR conditions over western Washington from January 10 to 12. Forecast guidance indicates 100–150 mm (4–6 inches) of rain over the Olympic Peninsula, 50–100 mm (2–4 inches) over the northern Washington Cascades, and 25–50 mm (1–2 inches) over the Cascade foothills, with freezing levels rising above 1 830 m (6 000 feet).
