Although probably no longer of relevance to the question posed, an excellent source is NWHikers.net.
The forums, well moderated, basically cover the spine of the Rockies, from BC-AB down to the US-Mexican border, with spillover on each side (California, Montana, Idaho ...). The site is Washington State-focused, but posters have seemingly been everywhere.
The site is also very good for road and trailhead conditions, including latest round of break-ins. The rangers at info centers try hard to keep up with mischief but rely to some degree on reports from LE and hikers.
Heavy rains may close access roads because of mudslides or streams rerouting and flowing across roads.
It may be easiest to learn about such issues on the forums.
Thank you Coldbrook for posting the info here.
Hiking is what keeps you young of mind and heart. When the going gets tough, the tough get going..............
