The FS is updating this page once a week (Thursday eves) but checking trails far more often. In my experience, they've been really diligent and are opening trails right as they dry out. THese aren't blanket closures stemming from a "we can't be bothered" attitude. And they have to
do some trail work as well...
You can also check here, which is updated more frequently but is bike-focused:
