Recent weeks brought several strong systems with rainfall warnings for North Shore areas. This pattern often continues into November which increases the chance of high streamflow and localized flooding.

Where the risks rise in November

The North Shore mountains and Tri Cities hills focus moisture. Long rain events saturate soils which drives water toward foundations and creeks. City programs across the region have strengthened fall storm readiness with more pumps, sandbags, and drainage work.

Home preparation checklist

• Clean gutters and extend downspouts well away from the foundation.
• Test sump pumps and add a battery backup with a high water alarm.
• Keep storm drains and driveway grates clear of leaves.
• Move valuables and documents off the floor in basements and crawlspaces.
• Place water leak detectors near the water heater, laundry, and mechanical room.
• Prepare an emergency kit with water, food, and needed medications for at least three days. [oai_citation:6‡Vancouver Coastal Health](https://www.vch.ca/en/storms-and-flooding?utm_source=chatgpt.com)

What to do in the first 24 hours if flooding starts

1. Protect people first. Stay clear of power and deep water. If safe, switch off power to affected areas.
2. Stop or divert water. Check exterior drains and downspouts. Use a utility pump if water pools.
3. Document the loss. Take photos and short videos inside and outside. Save all receipts.
4. Extract standing water. Use a wet dry vacuum or pump. Never use a household vacuum.
5. Start controlled drying. Set dehumidifiers and fans. Keep windows closed to hold humidity in range.
6. Call for assessment. Get moisture mapping and a clear scope for repairs and insurance.

FAQs

Where can I see live alerts for my neighbourhood

Use Environment Canada for local weather warnings and the BC River Forecast Centre for river advisories and flood watches or warnings. [oai_citation:10‡Weather Canada](https://weather.gc.ca/warnings/report_e.html?bcrm1516=&utm_source=chatgpt.com)

What is a High Streamflow Advisory

It means rivers are rising or expected to rise quickly. It warns of fast currents and possible minor flooding in low areas without a formal flood watch. [oai_citation:11‡BCRFC](https://bcrfc.env.gov.bc.ca/warnings/?utm_source=chatgpt.com)

Should I open windows during heavy rain

No. Keep windows closed and run dehumidifiers and fans for controlled indoor drying.

Call when water reaches walls or multiple rooms, when there is sewage, or when you cannot remove water and start drying within the first day.
