forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 4 PM PST Monday 1 January 1996 for
tonight Tuesday and Wednesday.
The next scheduled forecast will be issued at 7 PM.

Synopsis for coastal BC.
  A Pacific frontal system will exit the north coast this evening and
cross the central coast overnight then follow across more southern
regions on Tuesday.  Rain associated with this system will be heavy
at times over many areas with snow and local freezing rain expected
through inland sections of the north coast this evening.  As a result
weather warnings for these occurances remain in effect.  Also wind
warnings for strong southeast winds are continued for the northern
mainland coast and northern Vancouver Island until the system passes
this evening.
  A drier and cooler airmass follows in the wake of the frontal
system.  It will invade northern regions Tuesday and reach more
southern areas on Wednesday.  This will bring temperatures down to
more normal seasonal values.

mountain weather forecast for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Monday 1 January 1996 valid until midnight Tuesday.  The next
scheduled forecast will be issued at 6:00 AM PST Tuesday.

Precipitation intensity is forecast as an
hourly rate of snowfall water equivalent.

no pcpn  1 to 2 mm  3 to 4 mm  5 to 6 mm  more than 6 mm

discussion.
   A frontal wave lies over the southern Alaska panhandle this
afternoon with a warm front extending south-southeast along the
mainland coast and a cold front southwestward. The wave will move to
lie near williams lake by 4am Tuesday with the cold front extending
southwest through port hardy. By 4pm Tuesday the wave is in southern
alberta. The cold front extends westward through the southern
interior of BC then becomes a warm front on the coast. This warm
front extends through comox then to a new low pressure centre about
300 miles off the washington coast.
   Precip near the frontal wave is moderate to heavy as far south
as the central coast but becomes lighter and spottier southeast
from there along the warm front. Precip is also locally moderate
along the cold front that extends southwestward and becomes the next
warm front.
   Warming aloft is raising freezing levels with pockets of
freezing rain likely over inland sections of the northern mainland
due to some cold air still trapped in the lower levels. Warm air
will penetrate more southern regions tonight and Tuesday while a
sharp drop in freezing levels will follow in the north behind the
system.

Freezing level..south..1300 metres rising to 2400 metres by Tuesday
morning. North..1400 metres with near freezing layers to 1800 metres
lowering to the surface by Tuesday evening.

Extended outlook.
Cooler air will move to cover the entire coast by Wednesday
afternoon as the front continues to the southeast and away from the
district. A relatively dry northwest flow on Thursday and Friday will
result in only the chance of light convective flurries.  Freezing
levels all three days will be surface except 1000 metres in the
afternoons.

South coast mountains.
Warnings.. None.
Light today and this evening. Becoming moderate from the north
beginning overnight lasting through Tuesday.
Mountaintop winds..west-southwest 20 to 40 km/h rising to 50 to 70
overnight. Winds easing to southwest 40 late Tuesday.

confidence..
Fair to good. Offshore low centre May delay movement of front down
coast. This May give rise to greater precip amounts for central and
southern regions. Will monitor and consider public warnings.
