Federal & State Reporting Station Locations

The Yosemite Backcountry is notably devoid of both state and federal real-time reporting stations. That's different from the resources we have drawn upon while hiking down from Lake Tahoe.

Planning our gear selection for our hike South from Lake Tahoe we have referred to a reasonable selection of real-time temp, wind, rain, snow, and humidity ground reporting stations.

This real-time data gives us both current and historical knowledge of the range of temperatures we can expect to experience at various points down the trail.

Alas, we now face a real shortage of ground reporting stations as we enter the highest and hardest section of our trip down from Lake Tahoe to Tuolumne Meadows, the notorious "Five Canyons" of the North Yosemite Backcounty.

The Five Canyons between Wilmer and Virginia Canyon are a quick series of closely-spaced high elevation ridges scrunched close together divided by deep canyons.

Yet the reporting stations around Yosemite should impart the information to give us insights into the conditions we will experience and the gear we'll need.

Trail Guide Information

comments

This Weather Page, like the trail guide it is a part of, covers the High Sierra Trails from Meeks Bay down to the Mount Whitney Portal. Both the trail guide and weather page from Sonora Pass to Tuolumne Meadows are under construction. Therefore the trail guide remains split into two branches tracking both the Tahoe to Yosemite Trail and Pacific Crest Trail routes on their divergent paths South across Highway 108 to their junction below Bond Pass on the way to Tuolumne Meadows.The Pacific Crest Trail hikes through Sonora Pass while the Southbound Tahoe to Yosemite Trail route is offset by 9 miles, continuining South from the Tahoe to Yosemite Trailhead at Kennedy Meadows Pack Station.

Permits

National Forest Boundary runs North and South along the Sierra Crest across Sonora Pass. From Sonora Pass we hike South into the Emigrant Wilderness or North into the Carson Iceberg Wilderness. The NF boundary line bends around the North end of Yosemite National Park. National Forests at Sonora Pass West Slope: Stanislaus National Forest. East Slope: Toiyabe National Forest. WildernessNorthwest of Sonora Pass: Carson Iceberg Wilderness, Stanislaus National Forest. Northeast of Sonora Pass: Carson Iceberg Wilderness, Toiyabe National Forest. South of Sonora Pass: Emigrant Wilderness, Stanislaus National Forest.

Be Ready for the Range: Basic Facts Basic High Sierra Weather Resources for the Backpacker

The Sierra Crest is noted for having the capacity to produce four seasons of weather during a single Summer Day.

Rain, snow, hail, fog, lightening, and a bit of sunshine can all happen in quick sequence.

The High Sierras are noted for rapid changes in weather and temperature, and the sudden appearance of harsh weather trends. You may experience anything from intense heat to bitterly cold Summer snow storms. Or you may not.

In any case, weather must be considered and proper gear preparations made to deal with the range of weather BEFORE entering the High Sierras.

Long Distance Backpackers who were on the High Sierra Crest in early August of 2009 experienced just such a series of Summer Snow Storms.

Temperatures dropped to the high teens and low twenties, snow and hail fell which partially obscured the trails, and all of those who entertained the misconception that the Sierras only have fine weather during the Summertime were bitterly disappointed. Luckily for the many backcountry travelers who were not properly prepared, those storms blew apart, rather than consolidated and deepened.

Weather considerations should guide your gear selection.

High Sierra Weather Resources

 

Always check the National Weather Service Satellites, Maps, and Forecasts

The NWS Satellites will give you an orbital view of potiential storm activity far off the coast of California. Combined with the NWS Maps and Forecasts, you can anticipate weather. Note: especially check the 28km infrared and water vapor animations.

 

Check the National Weather Service Maps

NWS Maps Note: Especially Check the 24 to 48 Hour fronts and Precipitation Maps.

 

Consult the National Weather Service Home Page

The National Weather Service Home Page displays large and small scale weather warnings which may pertain to your High Sierra backpacking plans.
