Sunday, January 10th 2021, 7:13 am - Saturday afternoon was the longest calm stretch people on the Pacific coast can expect for awhile.
The brief break between systems Saturday gave way to another round of rain and strong winds at the coasts by the evenings, set to last into Sunday somewhat, as will snow at the mountain levels. More substantial doses of precipitation area ahead next week, however, though with a reduced impact from snow in the mountains. For a closer look, see below.
- Rain continues into Sunday morning, as does snow for the mountains, with a second round of the latter in the evening
- Strongest winds for Haida Gwaii will peak overnight, in the morning for the north and central coasts Sunday morning
- Multiple systems lining up for next week
SUNDAY: (BRIEF) BREAK BETWEEN UNCEASING DELUGES, WINDS PICK UP
January hasn't been too kind to B.C., with several successive systems ushering in unrelenting rains and alpine snow. After a brief break Saturday morning and afternoon, the next round of rain reached the coast later Saturday, thanks to a Pacific front. But this system won't be nearly as impactful as prior lows this month.
Through Sunday, 5-15 mm is expected for the Lower Mainland and 20-50 mm is forecast for Vancouver Island.
As for the winds, strong gusts in the hardest hit areas, in the 80-100 km/h range, will ease have eased through the overnight in Haida Gwaii, and then diminish over mainland areas of the north and central coasts by early Sunday morning.
In addition to the rain and strong winds, there will also be mountain snow for parts of the alpine regions. Snow, heavy at times will continue Sunday into Sunday morning, and pick up again Sunday night with another front approaching the area.
In addition to the heavy snow, local blowing snow from strong winds will reduce visibilities at times. A winter storm warning is in effect for Haines Road region, with a watch in place for the South Klondike Highway.
Because of the fresh snowpack, avalanche danger ratings remain moderate to considerable through the mountain peaks.
B.C. SOUTH COAST - GET READY FOR PLENTY OF RAIN IN THE DAYS AHEAD
NEXT WEEK: THE DELUGES RETURN
But more substantial precipitation won't be far behind: A moisture-laden system is en route for Monday, and another on Tuesday.
All together, western Vancouver Island and higher terrain north and east of Vancouver are looking at 100-200 mm of rain through next week, and up to 40-80+ mm for parts of the Lower Mainland and Metro Vancouver.
In the mountains, snow/freezing levels will initially be low enough for snow at the ski areas and hard travel through the passes, but milder air will quickly send them above 1500 metres in short order.
"An even milder system is ahead late next week, with rain into the alpine regions," Weather Network meteorologist Doug Gillham says.
