TVI Alert: Heavy Rain for BC Coast November 16 – 17

Posted November 14, 2019 - 4:49pm

Environment and Climate Change Canada has released a weather notification for heavy rain on BC’s Coast, from early Saturday morning through mid-day Sunday. This weather event could cause localized flooding, increased risk of landslides and debris flow, high streamflow, and debris-related power outages.

  • Total rainfall amounts are currently forecast between 90 and 140mm over the 36-hour period spanning early Saturday morning to mid-day Sunday.
  • The heaviest rainfall is expected over the West Coast of Vancouver Island from Ucluelet to Winter Harbour, with 140mm expected for Tofino, and up to 200mm expected for Zeballos.
  • High streamflow is expected in the North Island, especially in the Port Hardy and Port Alice areas. The River Forecast Centre will monitor streamflows and high streamflow advisories or flood watches may be issued.
  • Strong southerly winds with gusts up to 90km/h are forecast along exposed coastal sections of West Vancouver Island on Saturday.
  • A drier pattern is expected from Sunday evening onwards with seasonal temperatures and freezing levels returning to approximately 1000m.

How to Drive Safely in Strong Wind and Rain:

1. Anticipate gusts and take special care in high-wind areas.

2. Notice larger vehicles, such as tractor-trailers and recreational vehicles. They are more susceptible to high winds and drivers may have difficulties staying in their lanes.

3. Keep a firm grip on the wheel with both hands.

4. Take your time. Slow down to help avoid hydroplaning.

5. Turn your full headlights on, not just your daytime running lights.

6. Give other vehicles more space.

Other Tips for a Safe Stormy Weekend:

1. Make sure that your outdoor furniture and accessories are safely stored or firmly secured and that all gates and doors that need to be locked, are.

2. Remember that just 15cm of moving water can knock you off your feet and water just 60cm deep can sweep a vehicle away.

3. Just in case: Have flashlights, spare batteries, bottled water, a power bank fully charged, food supply that doesn’t require cooking, and a first aid kit.

4. Telephone service, both land-line and mobile, could be interrupted. Plan alternative ways to communicate and receive emergency information for both staff and guests.

5. Test generators regularly, fill fuel tanks in advance of the event and protect fuel tanks from rising waters. Even if the generator is unaffected, water in the fuel will prevent it from running.
