Snowpack Summary Dec. 14, 2018
Posted by Allen Giernet @ 10:00am
This summary applies to backcountry areas only.
The Bottom Line - Limited snow/ early season
Due to the recent temperature swings of the past week we can expect to find fast and firm conditions in the morning and softening midday. We have experienced warm afternoon temperatures with below freezing or near freezing overnight temps. A week ago we received reports of wet loose natural avalanches. There is the possibility of small wet loose avalanches on E,SE,S and SW slopes as the day progresses where snow still exists. Ultimately we have little snow at this time and can expect settling where snow has remained due to the warm afternoon temps.
Our bigger concerns will be firm conditions in the morning that could remain through the day on Northerly and Sheltered locations. A slip could result in a slide for life situation. Early season conditions exist with many obstacles that could lead to catastrophic results if any type of slip or slide is experienced. Travel with caution and be well aware of your terrain and surroundings at all times.
Avalanche Concern #1
Wet Loose avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
General Summary
As we have warm temperatures forecast for the weekend the afternoon warming will create a possible potential for Wet loose avalanches. Sunday evening into Monday will bring a a cold front through the area with a slight chance of snowfall. Accumulations will be minimal at best as forecast for now. This will maintain firm conditions throughout the mountains where snow exists. Tuesday through the end of the week brings warmer temperatures and the possibility of wet loose avalanches in the afternoon on E,SE,S,SW and W slopes.
Always practice use of avalanche skills when entering avalanche terrain and on steep slopes. Travel with a partner, use proper safe travel practices and carry a beacon shovel and probe. Most importantly know how to use them!

Avalanche level 1 presented by National Ski Patrol & SCSAC
Class session is Jan. 8 & 10, 2019 With field session options #1 Jan. 12-13 #2 Feb. 9-10 #3 March 2-3 To sign up go to Registration |
12-17-18 Colder today with cloudy skies, moderate Southwest winds shifting to Northwest this evening and a slight chance of snow showers. Snow levels will be around 7,000'/ 2,134m with minimal accumulation of trace to 1"/ 2.5cm if at all. The chance of snow will be slightly stronger the farther North you go in our mountains. This is the very edge of a diminishing low pressure trough passing to the North. Tuesday will see the return of high pressure and much warmer, dryer conditions through the week. Temperatures will be above seasonal average by mid week through Friday. The high pressure system will weaken for the end of the week and bringing cooler temperatures for the weekend.

Fundraising
campaign
We are raising funds to purchase and install the first of several weather stations at remote locations in our local mountains. This will bring us much needed pertinent data from above snow line that we doe not have reliable resources for. Satelite link up will bring us snow depth and amounts, along with wind, temperature and much more and will be available to the public.
Our goal is to raise $10,000 to purchase the equipment, cover installations costs and provide for a much needed overhaul of the website.
Please contribute to make this a reality for us all. Click on the donate button below and come out to join our annual fundraiser event at Mt. Baldy
Goal: $10,000 Recieved: $2,500.00

Awareness
There are avalanches in So Cal. This sign is on the road just before Mt. Baldy trailhead
General Caution
You should always use safe terrain management and carry avalanche rescue equipment in the backcountry. Most avalanches are triggered by someone in the party or the victim. Practice with your rescue gear often and be prepared should the worst happen. Though we do not have an avalanche forecast center in this area as of yet, the information posted and shared here as well as the resources available on this site will help to make informed decisions for your backcountry travels. Use avalanche forecasts in your travels wherever available and be aware that avalanche ratings are general information. Elevation, location, geographic variability’s, slope aspect and angle all have effects on the particular area you travel in. This is only one piece of the information you should use in your decision making process. There is no substitute for avalanche education, for more resources and information as well as education please refer to our resources page.
