Heavy snow at high altitudes mostly in the South Sierra preserves the:

SNOW TRAVEL HAZARD,
but now mostly limited to higher up the flanks & crest of the South Sierra.

Still lots of snow on South Sierra & protected parts of North Sierra Crest, less on others.

Protected areas full of snow in N & S Sierra.

High Altitude Trips are STILL SNOW TRIPS

Beginning of September

2018

Typical Year : Wet years extends the mosquitoes’ reign past the 15th, Dry years shorten it.
Wet basins and lakes that hold water on vast sheets of solid granite below their green-grass coverings feed the mosquitoes later into the season than terrain that drains.

Thus we will find “holdout zones” where local mosquito populations remain high long after the surrounding terrain has dried out. My advice when you encounter one of these zones: RUN!

2015: Drought. Weird tropical weather through July. August to typical conditions, but under extreme drought context. Thus August began running up into one of the worse fire seasons ever. September's weather will decide. Massive El Nino Conditions are boiling the Central Pacific. Somebody is going to get flooded.

DANGERS
Monitor weather for afternoon Thunderstorms

Beware of dangerous fording conditions

Mosquito conditions are typically going Hog Wild during this time of year.
Not during 2015!
Mosquito Populations are still being depressed by the drought conditions, despite the Spring and Summer tropical rains.

Mountain Safety

Thunderstorms?

As snow travel and fording dangers receede on the High Sierra terrain, the next danger grows in the skies.

July brings the peak of the Summer Thunderstorm Season in the High Sierra.
These are typically local weather, caused by heat waves in the San Joaquin Valley swept up the West Sierra Flank.

Hot wet air on a fast ride up the West Sierra flank to high elevations squeezes out what can be substantial daily rain and lightening activity lasting between 2 pm and sunset.

Don’t cross open ground under one of these storms. They are deadly. Lightening and Fording are the leading causes of High Sierra backpacker deaths.

Story
Caught Out with Bubba & Dave

 

2015 HISTORY
This year's constant series of thunderstorms are tropically born, not local. These thunderstorms are the product of distant moisture-rich tropical air being driven North by air currents generated by the intense tropical thunderstorm activity that generated them in the first place. These moisture rich airs are then sucked across the Sierra by an aberrant series of stubborn unstable low pressure zones over California and the West Coast of the U.S.
