As high as it is possible to get!

South Coast Date Issued: 1/17/2005 12:00:00 AM
Valid Until: 1/19/2005 12:00:00 AM
Forecast of Avalanche Danger: Monday Tuesday Wednesday
Alpine Extreme Extreme High
Treeline Extreme Extreme High
Below Treeline Extreme Extreme High


Travel Advisory: Anytime rain falls on cold dry snow a large avalanche cycle is imminent. We are now in this situation where rain is falling up into the alpine abruptly after very cold weather. The avalanche danger is now Extreme and will remain Extreme or High through Wednesday. You can expect to see monster slides in well defined paths and small avalanches in unexpected locations. The best thing to do in times like these is stay well away from avalanche terrain. In the longer term, let’s just hope that there is still some snow left by the weekend.
Avalanche Activity: A widespread avalanche cycle is expected to occur Monday night through Wednesday. Some of these avalanches may be very large and destructive running well into or beyond normal runout zones.
Snow Pack: Very weak snow layers that formed near the surface during the cold bout of weather during the past few weeks are being soaked by rain.
Weather: A Pineapple Express has set up with a warm tail of moisture all the way back to Hawaii. With strong jet stream support acting as a conveyor belt for storms, expect copious amounts of precipitation. Unfortunately, after 20 cm of snow expect up to 150mm of rain. The freezing level is supposed to rise between 2300 and 2500 m on Monday night and remain there through Wednesday. Associated with these storms are very strong southwesterly winds.

I'm scared. If the avalanche risk is EXTREME even below treeline, am I safe even in the house in Chilliwack??? I think I will sleep with the Barryvox on tonight.

Twink - okay Mr. Stupid spilly-pants soggy-bottomed - rain on my parade - pineapple stupid-head express.

Dru - If you do - better make sure you have it set to send.

Heard something about a bunch of houses in Chilliwack getting new "sunken" livingrooms. With all this rain, perhaps the ABS would be a better choice?

I just love the term Pineapple Express. I always imagine sweet, sugary tasting rain for some reason

Maybe I should order a Hawaiian pizza tomorrow and wash my poorly neglected vehicle (in the rain) before it freezes up again!

the SAS handbook my boss gave me for x-mas (which i silently gaffawed at) proved worth keeping. in anticipation of a major outside flood it recommends pre-flooding your house with clean water to mitigate all that dirty gucky flood water damage. can't comment on the insurance end though...not insured from outside flooding?; but insured for inside flooding?

Rather than flood it with water why not just rapidly fill the whole house with waterproof polystyrene?

Forecast of avalanche danger beginning Tuesday, January 18, 2005:

Day:\Monday p.m.\Tuesday\Wednesday
Alpine:\Extreme\Extreme\Extreme
Treeline:\Extreme\Extreme\Extreme
Below Treeline:\Extreme\Extreme\Extreme

Update: Tuesday January 18, 17:00 Continued heavy rain will further destabilize the snowpack and cause an Extreme avalanche danger on Wednesday. We are concerned that continued rain will further weaken the snowpack causing unusual wet avalanches and even slush flow avalanches. These slides can initiate from very low angle terrain and have the potential of traveling long distances across relatively flat terrain. We recommend that people stay away well away from avalanche terrain. Routes through the forest may also not be safe due to unstable slopes high above in the alpine.

Travel Advisory: Anytime rain falls on cold dry snow a large avalanche cycle is imminent. We are now in this situation where rain is falling up into the alpine abruptly after very cold weather. The avalanche danger is now Extreme and will remain Extreme or High through Wednesday. You can expect to see monster slides in well defined paths and small avalanches in unexpected locations. The best thing to do in times like these is stay well away from avalanche terrain. In the longer term, let's just hope that there is still some snow left by the weekend.
Avalanches: A widespread avalanche cycle is expected to occur Monday night through Wednesday. Some of these avalanches may be very large and destructive running well into or beyond normal runout zones.

more EXTREME, HIGH, HIGH this w/e . but i think you're onto something here - have you considered the inflatible foam insulation? a drawback or possible benefit, if you don't anchor the house well, is that your abode might float away

I don't think there is any avalanche risk below treeline around here because there is no snow below treeline. It's like June but with rain!!
