Storm archive
This corridor has three kinds of weather day: the rare winter storm that snows in Mountain Pass and closes the California run, the summer monsoon cell that floods a wash or the Virgin River and stops the Gorge, and the wind day that parks the trucks. The archive below is drawn from the public status history, so every entry is a real logged change, not a remembered one.
The benchmark storm in living memory is the February 2023 sequence, when back to back Pacific storms snowed Mountain Pass hard enough to shut I-15 between California and Nevada, the one closure every regular on this road measures the rest against. The corridor also carries quieter archives: monsoon nights when the Virgin River ran high through the Gorge, and spring wind days when gusts over the passes and the open desert held high profile vehicles for hours.
As the hourly logger records new changes, the storm days appear here in full. For what to do when one arrives, the storm playbook turns this archive into decisions, and the status history keeps every change, storm or not.
