Storm archive
Storm days are the days this site exists for, and they deserve a record. Every storm day leaves its trace in the status history: the traction postings, the closures, the reopenings, timestamped as they happened. This archive collects those traces so a February argument about what the canyon did in January has an answer.
How a storm day gets archived
The archive is automatic, which is what makes it trustworthy. The hourly logger writes an entry whenever a corridor's status or traction posting changes, and a storm day is simply a day dense with entries: the evening before, a Class posting up to 24 hours ahead of the snow; the morning, control closures in the Cottonwoods; the afternoon, reopenings in sequence. Nothing here is written up after the fact from memory.
On the day itself, the work follows the storm day playbook: verdicts refreshed, closure pages live, and the media page updated so local news and radio can quote the status with a source attached.
