mountain forecast guidance for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 4 AM PST
Wednesday 13 December 1995 valid until midnight Thursday.
The next scheduled guidance will be issued at 2 PM today.

Synopsis.
   At 4 AM an active frontal wave was near southwest Vancouver
Island with a trowal westwards along 50n to spiral into a 980 mb low
near 48n 136w. Deformation zone extended to an e-w line near cape st
james.
   Low has been moving ene 15 knots and is expected to stall near
northern tip of Vancouver Island and weaken tonight. Frontal wave
will cross south coast by early afternoon with trowal weakening over
south section of central coast today. Cool unstable air will move
onto coast in wake of front becoming enhanced in low level inflow
along south coast this afternoon and evening.
   Flow will ease and convection will become light all areas
overnight.

Freezing level..in the north..600 metres mainland coast to surface
inland. In the south..1200 metres rising to 1500 metres this morning
and lowering to 1200 metres tonight.

Extended outlook.  A weak upper ridge will build across the south
Saturday suppressing convection there. A more intense system will
cross the coast Sunday bringing rising freezing levels and
significant precipitation to the coast. A brief respite with
lowering freezing levels and showers or flurries before another
frontal system approaches from the west late Monday.

South coast mountains.
Warnings..snowfall warning for Whistler. Heavy rain warning for howe
Sound. Wind warnings for Sunshine Coast all of Vancouver Island
except extreme south.
Light becoming moderate locally heavy by late morning. Light locally
moderate convection this afternoon and evening. Light overnight and
Friday.
Mountaintop winds..southerly 40 to 70 km/h rising to southeast 70 to
100 this morning and easing to southwest 40 to 60 this afternoon.

Central coast mountains.
Warnings..wind warning for coastal section of central coast.
Light today except locally moderate extreme south this afternoon.
Light convection tonight and Friday.
Mountaintop winds..southeasterly 60 to 90 km/h easing to south to
southwest 40 to 60 km/h late this afternoon.

North coast mountains.
Warnings..none.
Nil to light today tonight and Friday.
Mountaintop winds..southeasterly 20 to 40 km/h easing to southerly
10 to 20 tonight.

Confidence..fair. Track of low near 48n 136w uncertain. Expect it
will track further south than numerical guidance indicates to stall
near northern tip of Vancouver Island tonight. Thus dont expect
precipitation with deformation zone from system to reach further
north than half way up central coast.
