El Niño update: Westerly wind bursts during January were very unusual and record-breaking in some areas. Warm water is now moving across the subsurface Pacific and will probably start to surface in February and March. By mid-2026, ocean-atmosphere El Niño coupling is possible.

In case you missed it live, a full recording of my rapid-response livestream regarding news surrounding the proposed imminent and sudden dismantling of the National Center for Atmospheric Research (NCAR) is now available. youtu.be/FTKW68RqdkE

Holy shit…

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, & disaster research underpinning half a century of progress in prediction, early warning, & increased resilience.

Okay… I’ll step back out from under my rock for this one. 🫣 That is one wild run coming out of the European model suite tonight… Feast your eyes, but be wary of the modeling whiplash ahead. 00Z ECMWF deterministic model wants to drown Southern California. #CAwx

Cuts have consequences, illustrated. As seen on TV 📺

SHELTER IN PLACE. SB County areas associated with the Lake Fire. Flooding/debris flow may be imminent or occurring. Go to innermost room or higher ground such as a second floor.

Update: DOGE has ordered firings and buyouts at the federal agency that operates water infrastructure in California. "Water experts should manage our water systems, not tech executives." latimes.com/environment/stor…

This is deeply troubling. NWS forecasters don't just come in and put a forecast together. They make processes for all forecasters so much better. I encourage you to read @mammatusman last forecast discussion he wrote to see how deep this cut really is. This is just one example: forecast.weather.gov/product…
