For the second time in three days, another warning for heavy rainfall has been issued for the Tri-Cities.
This time, up to 120 mm of downpour is expected near the mountains across the region and 60 mm in southern sections of B.C., which includes Coquitlam, Port Coquitlam, Port Moody, Anmore and Belcarra.
As of 11:21 a.m. today (Nov. 26), the rain is forecast to start midday Saturday (Nov. 27) and potentially ease off by Sunday night (Nov. 28).
According to Environment Canada meteorologists, the amounts will vary for Metro Vancouver as another weather front system moves along the coast.
"Strong warming will accompany this system causing snow levels to rise well above the mountain tops on Saturday," the update reads, noting winds should be on the lighter side at about 20 km/h inland and 40 km/h near the water.
"Snowmelt will contribute to run off, increasing the risk of flooding and possibly impacting vulnerable landscapes and infrastructure."
Flash and localized flooding, as well as water pooling on roads, is to be expected in the Tri-Cities, the national service adds, so residents are encouraged to watch out for possible washouts near rivers creeks and culverts.
The rain may also alter patterns at given times on the weekend from heavy to drizzle.
During the previous rainfall warning — which began Wednesday morning (Nov. 24) lasted for 48 hours — Coquitlam's Burke Mountain gauge recorded more than 125.5 mm of rain.
In the last 24-hour period that ended at 11:55 a.m. today, 46 mm was recorded at the Harper Road station.
City environmental and worksite bylaw officer Angela Yeung encourages residents to prepare their homes, businesses and worksites for the incoming inclement weather.
"Erosion and sediment control measures must be implemented and maintained," she says.
"Disturbed surfaces should be well protected and catch basin filters should be cleared of debris or removed in areas prone to flooding."
HOW CAN I PREVENT POTENTIAL FLOODING?
The City of Coquitlam has provided safety measures to consider before, during and after a rainstorm, including avoiding any unnecessary travel.
At your own homes, you're encouraged to:
- Check on neighbours who might need assistance, including prior to the storm to see if they need help to get prepared
- Use the city's catch basin map to find catch basins close to your property and keep them clear of leaves and debris
- Ensure gutters on buildings are clear of leaves and debris, and rake up leaves to prevent them from plugging drains
- Secure anything that might blow away in a storm, including garbage carts and lawn furniture
- Bring carts in from the curb after they have been emptied to avoid the risk on high winds knocking them onto the road
- If you have a missed collection due to a knocked-over cart, contact Waste Connections Canada at 604-636-3520
If you must travel across the city in the next day or two, consider the following:
- Follow all road signs, including detours and road closures
- Do not walk or drive around barricades on roads as they have been placed there to protect public safety
- Treat any traffic signal that is dark or flashing as an "all-way stop"
- Report downed power lines to BC Hydro (1-800-224-9376) or *HYDRO (*49376) on your mobile
- If you come across a downed or damaged power line, stay back at least 10 metres
If you need to get in your daily 10,000 steps:
- Postpone hiking through forested parks and trails, in particular pathways along ravines or steeper slopes due to increased landslide risk
- Stay clear of fast-flowing rivers, creeks and potentially unstable riverbanks
- Watch for falling trees or branches
- Watch out for and avoid walking or driving through pooling water on roads and pathways
- Do not wade through flood water
