British Columbia flooding risks remain elevated Saturday as another moisture-laden system moves across the South Coast, bringing heavy rain, strong winds and the possibility of coastal flooding.
Environment and Climate Change Canada has issued a yellow rainfall warning for Howe Sound and the Sea to Sky region, where 40 to 70 millimetres of rain is possible from Saturday afternoon through Sunday night.

British Columbia Flooding: Rainfall warning covers Howe Sound and Sea to Sky
The latest warning says already saturated ground will have less capacity to absorb new rainfall after several storms earlier in the week.
Officials are warning that water could pool on roads and in low-lying areas, while washouts may occur near rivers, creeks and culverts.
The rainfall warning covers areas including Squamish, Whistler and surrounding parts of Howe Sound and the Sea to Sky corridor.
Environment Canada is also maintaining wind warnings and coastal flooding statements for several areas of the South Coast, including parts of Metro Vancouver, the Strait of Georgia, Greater Victoria and the southern Gulf Islands.
The coastal statements warn that higher-than-normal ocean levels, strong winds and enhanced wave activity could produce localized flooding along exposed shorelines.
Flood alerts and evacuation measures remain in place
In the Pemberton Valley, the Squamish-Lillooet Regional District has expanded an evacuation alert to cover all properties within the Electoral Area C portion of the valley.
The alert means residents must be prepared to leave on short notice if conditions worsen.
Emergency officials said significant impacts remain in the area, including localized flooding, damaged roads, debris, unstable slopes and difficult access.
The regional district removed a shelter-in-place advisory for the Pemberton Valley on Friday, November 13, but the evacuation alert remains active.
The Village of Pemberton continues to maintain emergency measures, including an evacuation alert for properties between 1674 and 2000 Airport Road and an alert covering the rest of the village.
Residents in affected areas have been told to monitor official notices, prepare essential medication and documents, and be ready to move quickly if an evacuation order is issued.
Road closures affect Squamish and Pemberton areas
Flooding has closed sections of Squamish Valley Road and Pemberton Meadows Road, according to current provincial travel information.
Squamish Valley Road is closed in both directions from approximately the three-kilometre mark to north of Pilchuk Creek Bridge.
Pemberton Meadows Road is also closed in both directions between Erickson Road and a point two kilometres south of Erickson Road.
Authorities are warning drivers to expect pooling water, debris, washouts and short-notice closures on routes across the South Coast.
Highway 99 through the Sea to Sky corridor and the Pemberton Valley remain among the areas requiring particular caution during the storm sequence.
Drivers should check current provincial road conditions before leaving and should never attempt to cross flooded roads or bridges.
River levels have eased, but hazards remain
The B.C. River Forecast Centre downgraded portions of the South Coast, including Howe Sound, the Sea to Sky region and the North Shore Mountains, to a high-streamflow advisory on Friday.
The centre said rivers in the region had generally peaked earlier in the week and were receding, although floodwaters beside rivers could take longer to drain.
Additional rain forecast for Sunday could cause river levels to rise again, even though rivers were not expected to return to flood stage at the time of the latest advisory.
High streamflow can still create dangerous conditions along riverbanks, including erosion, unstable banks, swift water, submerged roads and landslides.
The combination of saturated ground and renewed rainfall means conditions can change quickly, particularly near steep slopes, creeks and drainage channels.
What residents should do next
People living in evacuation-alert areas should keep phones charged, gather medications and important documents, and plan where they would go if they had to leave.
Residents should follow instructions from local governments, First Nations and emergency officials rather than relying on unofficial reports or attempting to bypass barricades.
Anyone in immediate danger should call 911.
The latest weather, road and emergency notices should be checked before travelling, particularly in the Pemberton Valley, Squamish Valley and other low-lying coastal locations.
Further updates are expected as rainfall totals, river levels and road conditions are assessed through Sunday.
