forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 10 AM PST Monday 18 December 1995 for
today and Tuesday.
The next scheduled forecast will be issued at 4 PM.

Synopsis for coastal BC.
  A moist and slightly unstable airmass has moved in behind a frontal
system that crossed south coastal regions this morning.  This will
result in generally cloudy skies and spotty shower activity for the
remainder of the day.  A few breaks in the cloud cover are also
possible through the afternoon hours.  This airmass will linger
tonight producing little if any precipitation.
  In the north skies will also remain mostly cloudy with a few
showers expected today and tonight.  The next Pacific frontal system
is moving quickly towards the coast and this system will spread
periods of rain to the queen charlotte islands this evening.
The rain will move to the remainder of the north coast overnight
reaching northern Vancouver Island by Tuesday morning.
Strong southeasterly winds will redevelop over exposed coastal
locations as the front approaches.
  On Tuesday the rain and windy conditions will continue across the
north.  The south can expect partly to mainly cloudy conditions but
only isolated shower activity is expected.

discussion
a low pressure system 250 kilometres southwest of the queen
charlotte islands will move northeastwards today and fill. The low
will lie over the Alaska panhandle near wrangell Monday morning. A
Pacific front associated with this low currently lies southwards
from the Charlottes. It is forecast to move eastwards to lie from
the eastern Cariboo to southern Vancouver Island by Monday morning.
The front will continue eastwards during the day tomorrow ending up
east of hope by the afternoon. Strong southeasterly winds and
occasionally heavy precipitation accompany the front. Wind and
precip will ease behind the front after it passes eastwards.

Freezing level..south coast..near 1800 metres east of the front
lowering to near 1200 metres west of the front Monday.
North coast..near 1100 metres east of the front with near or below
freezing layers inland lowering to 700 metres west of the front with
below freezing temperatures near the surface inland.

Extended outlook.
The southwest flow will continue. The next front will hit the north
coast Tuesday then slide down the coast to the south coast by
Wednesday where it will hit in a weakened form. Another front will
reach the north coast early Thursday and it too will slide down the
coast reaching the south late in the day. Freezing levels will
continue to be high in advance of these fronts.

confidence..poor. Precipitation amounts are very uncertain as
numerical models differ on their forecasts. No reports of heavy snow
have been received even though the weather pattern supports such a
prediction. Precipitation intensities will be quite variable in the
north behind the front due to the unstable nature of the airmass.

This mountain weather forecast was produced for BC ministry of
transportation and highways, snow avalanche programs and applies
specifically to those areas in the forecast.  If further information
or other products are required for local operations, please call
