PRECAUTIONS AND OPPORTUNITY
Some backpackers are observing patterns and trajectory of Winter storms and temps to find Hiking Windows into the
Winter Wonderland.
Others are watching the snow activity/pack to determine when the trails will clear enough to begin their Pacific Crest Trail or John Muir Trail backpacking trips.

Time to
Order Next Year's Permits!
Reserved permits for June 2018 now available from Yosemite, Hoover, and Desolation Wilderness Areas. In other words, Yosemite, Desolation, and Hoover Wilderness Areas all offer advanced reservations about six months ahead of your desired hiking dates.
This means now is the time to get your JMT permit application, along with other popular hikes, into the Man.

Last year, during 2017, at this point in time I was estimating a powerful, potentially catastrophic Spring Thaw.
We had snow along the Sierra Crest through the whole Summer. Again, each year's thaw depends on the Winter snowpack against the profile of Spring temps and precip.

Bookends of Extremity
2015 & 2017
Driest Year in History?
2015
2015 was the driest year in my life observing the Sierra, California, Nevada, and the Southwest, and likely across all of modern history, requiring a punch deep back into Ancient history to find its equal.
I had just started keeping the calendar in 2015, and did not specifically start noting the lack of snow across February, not until March, and we can see how it was ALL gone by the First of May.
2015
Earliest PCT Launch EVER
Bloom was resupplying PCT hikers in May, 2015, unprecedentedly early.
Extremes
2015 was an extreme example of a West Coast Drought during these drying and warming times.
2017
WETTEST YEAR
LATEST PCT LAUNCH EVER
The incredible dryness of 2015 was quickly followed by the deluges of 2017, which presented us with a three year streak where we recorded both the wettest and driest years in modern history within a rapid three-year succession.
What does This Mean
in
2019
?
These recent-past extremes are indicative of a system, more specifically, our region of the planatary weather system, that's out of, "wack."
Extremes
are the
New Normal
I'd say we are still looking at a system that will continue to produce extreme results, as the ancient balances that centered and held the range of our traditional weather patterns continue to break down from the inside-out, and the outside-in.
Not only are extreme events possible, they have become likely. |

There is a vast storm off the North Coast of Australia, (in the Southern Hemisphere!) that's totally suppressing Westward movement of heat along the Equatorial Band far to the East of Indonesia, which is helping to clog-up, and feed vast amounts of tropical moisture splitting-off up to the Northwest, from Southwest of Hawaii.
This map, when viewed today, shows this vast storm:
Note the Vast Low, off the coast of Australia. That's blocking and feeding the storrm activity we see, the TTM, that's flowing North-West from the Equatorial region hitting us today...
If you look at this, today, you will see that it is nothing short of amazing that the low off Aus is feeding Tropical downpours here!
