UPDATE NOTICE

The Northern Sierra Weather Section is under Active Construction, matching progress on the trail guide.

The Central and Southern Sierra pages are inactive & incomplete, and will remain so until I get to constructing the associated sections of the trail guide.

Consult the All Sierra Weather page for complete information, if not as well organized by Sierra region.

Our goal is to provide pinpoint backpacking weather conditions information to supplement trail guide descriptions with good gear-selection information. Thick information for all aspects of your trip planning considerations.

In the meantime we've got a bird's eye view of High Sierra weather informaton up and down the Sierra Crest on the All Sierra Weather page.

The custom weather pages covering the trails between Tahoe to Sonora Pass are almost completed. The rest will follow, eventually.

In the meantime, use the All Sierra Weather page.

The "point" of these various readings and measurements are to let us know when river flows get ripping.

We can rest assured the High Sierra fords will be raging when the Valley is threatened by high flows or under water.

Combined with our observations of the rate of the snow pack, above, and on the High Sierra Calendar, we can get some idea of river flows way up in the High Sierra.

Our Goal

Clarity

After using the snow and temp reporting stations to track our Fall into Winter and Winter into Spring's snow and temperature profiles we will turn to using them to monitor the change in weather bringing the rise of temps into the Spring Thaw.

We will now use our High Sierra reporting station observation tools to monitor the warming and melting snow pack in conjunction with deploying our water tools to observe the rate of rising rivers.
The pace of the melting and the rising of the rivers should give us a pretty good idea of just when the Spring Thaw River Flows are becoming dangerous, if not impassable in the High Country.

That's the goal, to determine when the main flow of the Spring Thaw reaches critical dangerous phases. In the meantime we can track the line of muck, melt, and mosquitoes as the thaw line leads an explosion of life moving up the Sierra Flanks.

We either want to be there as that happens, or wait awhile until it and the associated dangerous fording conditions calm down a bit. We do want to miss any catastrophic melts and flows... but your timing really depends on what you're in it for. We want to get the best picture of what's happening right now. It's up to you decide if that's good for you.

You decide if those conditions match your expectations, fitness, gear, and skills. But we've got to understand, even with as good a look as we can get using all the technical and personal means at our disposal, we are still entering the unknown.

Know That Clearly!
