Powerful wind gusts and thunderstorms target B.C

Wednesday, August 21st 2019, 8:47 am - Powerful wind gusts, snow and thunderstorms. B.C. wins this week's "weather bingo."

Just as parts of northern B.C. were blasted with some ridiculously inappropriate summer snowfall amounts over the weekend, the province remains the target zone for more wild weather through the first half of this week. Heavy rain, powerful winds, more snow and thunderstorms are all on the table through Wednesday with a brief warm-up expected ahead of a drastic cooling pattern. More on the timing and risk areas, below.


WEATHER HIGHLIGHTS:

  • Heaviest rain slides down to the Lower Mainland by Wednesday morning
  • Brief bump in temperatures before cooling pattern through late week and weekend
  • Stay up-to-date on the ALERTS in your area

HEAVY RAIN PROMPTS WARNING OVER THE NORTH COAST

A rainfall warning was issued for parts of the North Coast and Haida Gwaii Tuesday as a system pushing into the province threatened more than 50 mm expected in the hardest-hit areas. Though the threat for localized flooding in heavy downpours lingers, rain should ease through Wednesday morning in the north.

The South Coast and Lower Mainland saw a relatively dry Tuesday but showers are on the way for Wednesday. With much of the system's moisture spent in the north, however, much less significant rainfall amounts are likely for Vancouver Island and parts of the South Coast through the day.

In addition to the rain, powerful winds will strengthen through the pre-dawn hours on Wednesday with gusts over 100 km/h possible off the Pacific Coast.

Places like Sandspit in Haida Gwaii could potentially see hurricane-force wind gusts near 120 km/h early Wednesday, while northern Vancouver Island will see winds gusting close to 60-80 km/h on Wednesday afternoon.

"And once that trough crosses over southern B.C., the risk of scattered isolated thunderstorms develops for parts of Vancouver Island and across the South Coast on Wednesday afternoon," Hamilton says.

Temperatures will briefly soar across the south, but the warmup will be extremely shortlived thanks to a cold front, which sends temperatures tumbling by 10+°C by Thursday.

"We'll see some cool and unsettled weather persist across the province late week and through the weekend with a threat for rain showers and thunderstorms," says meteorologist Dr. Doug Gillham. "We're also watching the potential for a much warmer and drier pattern to develop during the final week of August."
