forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 10 AM PST Tuesday 19 December 1995
for today and Wednesday.
The next scheduled forecast will be issued at 4 PM.

Synopsis for coastal BC.
  A cloudy and unsettled weather pattern will persist across coastal
British Columbia for the next few days as a series of frontal systems
continue to move across the coast.
  A moist onshore flow will give clouds and patchy drizzle or showers
to most areas of the south coast today.  In the north a frontal
system will give steady rain and windy conditions from northern
Vancouver Island northward.  This front will edge towards the inner
south coast over the next 24 hours but it will continue to weaken as
it does so.  By the time it reaches the south coast tonight
precipitation amounts will be relatively light.
  The next frontal system will reach the queen Charlottes islands
Wednesday afternoon bringing more rain and wind.  In the south the
moist onshore flow from the Pacific will continue maintaining mostly
cloudy skies and scattered showers.  Temperatures will remain near or
slightly above normal.

mountain weather forecast for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Tuesday 19 December 1995 valid until midnight Wednesday.  The
next scheduled forecast will be issued at 6:00 AM PST Wednesday.

Precipitation intensity is forecast as an
hourly rate of snowfall water equivalent.
  Nil        light          moderate       heavy
no pcpn   up to 2.5 mm   2.5 to 7.5 mm   more than 7.5 mm

discussion.
A Pacific frontal system stretches from the Charlottes southwards to
just offshore Vancouver Island. This front is forecast to move
eastwards during the next 24 hours to lie from the central interior
to near Vancouver by Thursday morning. The front will weaken as it
moves eastwards and should dissipate during the day Wednesday.
Precipitation is generally light along the front and should remain
that way as the front moves across the coast. Freezing levels will
not drop significantly behind the front. A second weak front will
reach the north coast late Wednesday.

Freezing level..1500 metres coastal sections sloping to 1200 metres
inland south coast and about 800 metres inland north coast.

Extended outlook.
The mild southwest flow will continue with a split in the flow
offshore weakening approaching fronts. The front crossing the north
coast late Wednesday probably won't reach the south coast before it
dissipates. Computer models show another front crossing the coast
on Friday.

South coast mountains.
Warnings.. None.
Light locally moderate tonight and Wednesday morning. Nil to light
Wednesday afternoon and evening.

confidence..fair. Front is weakening and models show only small
amounts of precip with it and none behind it. This might be a bit
too optimistic but heavy precip is not anticipated.

transportation and highways, snow avalanche programs and applies
specifically to those areas in the forecast.  If further information
