2017
Backpacker
Alert through Spring into Summer!
2019 is working out very much like 2017.
Let's review the Status & Conditions
of
2017:
2017 BACKPACKER ALERT:
April 1 thru August 22, 2017. (coverage to 9-11)
The above was preceeded by the
MARCH 22, 2017 BACKPACKER ALERT
Note the parallels between the Winters of 2017 & 2019, and adjust the expectations of your PCT-JMT High Sierra Backpacking start date accordingly with the conditions...
These Old Alerts appear to apply as much today as they did in 2017.
2018
Feb 18, 2018
At this time l ast year, we were wondering if the snowpack would last until June. A cool Spring, with a couple of well-placed storms, barley stretched a thin snowpack into May.
2017
Feb 18, 2017
Two years, during 2017, at this point in time I was estimating the chances of a powerful, hot, tropical Spring storm triggering a potentially catastrophic Spring Thaw on a massive snow pack.
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.

John Muir Trail Hikers:
Past Time to
Order This Year's Permits!
Reserved permits for the whole Summer of 2019 are now available from Yosemite, Hoover, and Desolation Wilderness Areas.
First shot at June reservations began in December.
In other words, Yosemite, Desolation, and Hoover Wilderness Areas all offer advanced reservations about six months ahead of your desired hiking dates, and now the remaining dates across the whole Summer are available.
This means now is the time to get your JMT permit application, along with other popular hikes, into the Man, and see what hiking windows are still open.
For When?

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!
