PermitCast forecast
It is off-season. No permit is needed until June 15
Central Cascades does not ask for a permit here until June 15.
We pause the odds while a permit is off season or closed, because there is nothing to catch. They come back when it reopens.

It draws at 140 recorded openings across its 28 squares. Under that, the darkest square is chance rather than a pattern. Set an alert and every opening counts toward it.
