forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 5 AM PST Friday 15 December 1995 for
today and Saturday.
The next scheduled forecast will be issued at 10 AM.

Synopsis for coastal BC.
  A low pressure system lying near port hardy was producing showers
over most of Vancouver Island and the south coast early this
morning. In the north low cloud was reported near the coast with
clear skies inland.
  The low will continue to weaken as it drifts slowly eastwards
today. Showers and gusty winds will continue this morning but will
ease this afternoon as the system drifts away from the district. A
brief reprieve in the precipitation is expected tonight as a weak
ridge of high pressure attempts to build over the south. But the
next in the series of Pacific disturbances will spread more
precipitation to the coast by Saturday afternoon with another more
vigorous disturbance expected Sunday. Temperatures will continue
unseasonably mild over much of the coast.

mountain forecast guidance for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 4 AM PST
Friday 15 December 1995 valid until midnight Saturday.
The next scheduled guidance will be issued at 2 PM today.

Synopsis.
An upper cold low sits just north of port hardy at 4 AM with an
upper trough extending southwards. The system will slowly migrate
eastwards today to lie east of the south coast mountains overnight.
Convection will be heaviest near and to the east of the upper
trough. Moderate inflow will enhance the convection but this flow
will ease as the day progresses. Rising heights and drier air will
result in only isolated light convection over the north and central
coasts and west of the upper trough in the south. The arctic front
will remain stationary to the northeast of a stewart-nass line with
little weather expected with it.
A nw-se upper trough near 50n 150w is forecast to lie lie along the
mainland coast late Saturday afternoon. System will be weakening in
split flow but there May be enough punch to give a few hours of
light precipitation.

Freezing level..south..1200 metres outer coast to 1000 metres
inland. North..500 metres coast to surface inland.

Extended outlook.
A series of disturbances embedded in a west-southwest flow aloft
will cross the coast through the period. There is some uncertainty
as to where the main waves will cross the coast as the numerical
guidance is not consistent in position of the jet stream. But it
will be wet nevertheless.

South coast mountains.
Warnings.. Snowfall warning Whistler.
Light today with occasional moderate convection this morning. Nil to
light convective tonight. Nil Saturday becoming light in the
afternoon.
Mountaintop winds.. Southwest 50 to 60 km/h easing to west 30
tonight and rising to southeast 50 Saturday afternoon.

Central coast mountains.
Warnings.. None.
Nil to light convection today. Nil tonight. Nil Saturday becoming
light near noon.
Mountaintop winds.. Variable 20 km/h becoming southwest 30 this
afternoon rising to southeast 40 to 60 Saturday morning.

North coast mountains.
Warnings.. None.
Nil to light today. Nil tonight. Nil Saturday becoming light in the
afternoon.
Mountaintop winds.. Northerly 20 km/h today becoming west 20 this
afternoon and southeast 30 tonight. Wind rising to southeast 40 to
60 Saturday morning.

Confidence..good except fair on intensity of saturdays system
crossing coast. It appears system will be weak as it shears out in
split flow aloft.

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
