forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 10 AM PST Sunday 10 December 1995 for
today and Monday.
The next scheduled forecast will be issued at 4 PM.

Synopsis for coastal BC.
  Numerous weather warnings remain in effect for coastal British
Columbia as a layer of cold arctic air is overun by warm moist
Pacific air.  This combination is resulting in intermittent snow or
freezing rain over much of the inland sections of the central and
north coasts.  In addition outflow winds are blowing through most of
the mainland inlets in these regions giving reduced visibilities in
blowing snow along with very cold temperatures.
  In the south most areas are now reporting rain and the threat of
freezing rain has generally ended.  The exception to this is the
eastern Fraser Valley and parts of the howe Sound Whistler regions
where areas of freezing rain are still expected.  Rain from the front
will be heavy at times today and tonight especially along the west
side of Vancouver Island where 24 hour rainfall totals are expected
to exceed 100 millimetres by this evening.  Many inner south coast
regions will see 40 to 70 millimetres.
  Behind the front an unstable marine airmass will give showery
conditions on Monday.

mountain forecast guidance for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 6 AM PST
Sunday 10 December 1995 valid until midnight Monday.
The next scheduled guidance will be issued at 2 PM today.

Synopsis.
Arctic outflow conditions continue across all mainland areas and are
especially strong along the north and central coasts where wind gusts
in excess of 130 km/h have been reported at some coastal stations.
At the same time mild and very moist Pacific air is over-running the
cold arctic air. This is resulting in precipitation of various types
over the mountains. Mainly as snow on the north and central coast
although with some patchy freezing rain and with rain on the
extreme outer coast. The main baroclinic zone is currently stalled
over the south coast mountains. Considerable moisture and very mild
air is entrained in this southwesterly flow. Precipitation is
generally in the form of rain except for eastern sections where the
precipitation is wet snow or mixed rain and snow along with some
freezing rain. The baroclinic zone will move inland tonight and will
lie n-s through Revelstoke by Monday morning. Behind the front
freezing levels will begin to drop and the precipitation will become
showery. Rainfall amounts of 50 to 100 mm are expected on south and
southwest facing slopes in the south.

Freezing level..surface except near 2800 metres over the south
coast mountains. Above freezing layer aloft over north and central
coasts between 700 and 2000 metres.

Extended outlook.  Mild and wet conditions will continue as a
southwest flow aloft brings a series of systems across the south.
Generally cool and showery across north. Upper trough moves closer
to coast giving lower freezing levels and more showery precipitation
over all of coast.

South coast mountains.
Warnings..snowfall warning and freezing rain warning.
Moderate today becoming moderate to heavy tonight. Light locally
moderate Monday.

Central coast mountains.
Warnings..freezing rain  and arctic outflow warnings.
Light locally moderate today and tonight. Light Monday
mountaintop winds..southeast 20 km/h increasing to 40 to 60

north coast mountains.
Warnings..freezing rain snowfall and arctic outflow warnings.
Light locally moderate today becoming light tonight.
Mountaintop winds..southeasterly 40 to 60 km/h.

Confidence..fair. Considerable warm air moving in aloft and mountain
top sites have been slowly warming. However still very cold in some
valleys and outflow winds continue over most of coast. So the big
problem is the phase of precip ie.  Whether snow, rain, freezing
rain. In south most areas should eventually change to rain today but
remainder of coast not so clear cut.

This mountain weather forecast was produced for British Columbia
ministry of transportation and highways, snow avalanche programs and
applies specifically to those areas in the forecast.  If further
