Extreme Weather Conditions

Occasionally, North Vancouver and the Vancouver area experience periods of extreme weather - blizzards and cold, heat and humidity, heavy rainfall and high winds.

The City of North Vancouver receives an average of 177 centimetres of precipitation every year. A heavy rainfall advisory is issued when heavy or prolonged rainfall is sufficient to potentially cause local or widespread flooding or flash floods. Rain that is particularly heavy can cause traffic disruption, flooding and landslips, drainage and sewer problems and potential water contamination from runoff that may result in a water quality advisory.

When seasonal arctic air moves over our region the rains turn to heavy snow and strong winds. A snow warning advisory is issued when 15 centimetres or more of new snow are expected in a 24 hour period or less and wind warning advisories are issued for most B.C. coastal regions when sustained winds of 65 km/h or greater or wind gusts of 90 km/h or greater, are expected. Snow that accumulates can cause traffic disruption as sections of road may be slippery and driving conditions may be treacherous, especially on steep inclines and side streets. Heavy winds may cause trees and branches to fall causing power outages and road closures.
