Last Spring Snow Trips?
Once the Spring Thaw gets going the rivers and creeks will rage, making fording very dangerous.

When are the trails along the Sierra Crest going to be passable this year?
Upcoming
Weather
Probabilities
These three years highlighted above offer the potential range of Weather Conditions within which this year's PCTer,
"Start Date," the date you can reasonably expect to encounter fairly snow-free trails with post-deadly fording conditions, will be determined within. These are the historic limits of wet and dry, with a perfectly average year thrown in-between, for good measure.
This date, of course, depends upon your ability to navigate snow at high altitude, along with your ability to cross the various stages of the dangerous thaw waters draining off it.
And your fitness, of course. You are training, are you not?
You can get through before and after the period of high-flow runoff, but not during this phase.
How the conditions of the Winter to Spring
Transition we track this year measures-up to the classic trajectories of these three years cited above will inform potential PCT hikers about the snow/trail conditions along the High Sierra Crest they may reasonably expect to encounter during May, June, and July of this year measure-up against those of the Driest year in history against an Average Year, against the wettest Year in History...
This year of 2020 will fit somewhere between these historic parameters of the record Wettest and record Driest years that happened between
2015 and 2017.
As our seasonal start date for open access to trails along the High Sierra Crest will be adjusted according to the character and trajectory of this year's Winter to Spring Transition, we will watch it carefully.

Alex
We’re open fully and fish have been stocked.
First pct hiker was here yesterday.
Lots of snow up high.
Expect snow and high runoff until mid July at higher elevations.
Highway should be open over pass by memorial weekend.
We’re stocked and ready for hikers.
Thanks, Matt
BIG NEWS
2017:
Summer "Opening" of Trails "Put-Off" until it happens.
Late July?
I mean clear trails across the High Passes. On the Crest Trails.
