flood
Abnormal high tides combined with low pressure may produce minor/moderate coastal flooding.
Elevated water levels accompanied by strong winds and waves are expected, exceeding highest astronomical tides.
What:
Risk of coastal flooding due to storm surge coinciding with high tides.
When:
This weekend, with the highest risk of coastal flooding on Sunday.
Additional information:
The South Coast is entering a period of high astronomical tides as Earth reaches perihelion (Earth's closest point to the Sun). Also, a low pressure system will cross the region this weekend. This falling atmospheric pressure will help further elevate coastal water levels beyond predicted tides, thus increasing the risk of coastal flooding.
The exact track and timing of the low pressure centre remain uncertain at the moment. Wind strength will be contingent on the position of the low.
Moderate winds and storm surge can lead to washed up debris and erosion along coastal areas. Minor to moderate coastal flooding is likely along exposed shorelines, especially in the low-lying areas. There is a risk of locally significant flooding especially where onshore winds compound on the highest tides. Roads and walkways may be difficult to navigate due to flooding and/or debris, such as driftwood and rocks.

fog
Near zero visibility in fog is expected.
What: Widespread fog reducing visibility to near zero.
Where: Metro Vancouver.
When: Now until early this afternoon.
Remarks: A ridge of high pressure has settled over the Lower Mainland with cool and humid marine air trapped under a warm, stagnant airmass aloft. This has resulted in widespread fog this morning. Conditions are expected to improve early this afternoon when temperatures will start rising and mixing near the surface will help the fog to dissipate.

Special Weather Statement
Significant rainfall over the past week has increased soil moisture
to high levels across western Washington. This significant rain
has put extra pressure on soil instability, leading to an
increased threat of landslides and debris flows, especially from
recent burned areas. Precipitation will remain fairly light
through most of the weekend but a frontal system will move through
Sunday night into Monday, bringing a quick hit of heavier
rainfall which could act as a trigger.
Numerous landslides have already occurred across the area. More
landslides continue to be possible.
Areas most susceptible to landslides debris flows under these
conditions are steep coastal bluffs, other steep hillsides or
road cuts, and recent burned areas. A diminishing threat of
landslides and debris flows will continue for several days after
the rain ends.

Additional information:
More rainfall is in store over the upcoming days for the already saturated Fraser Valley.
A weather system is expected to move onto the South Coast today with heavy rain beginning tonight. On Monday, another system arrives with a more significant push of moisture. Rainfall amounts with this system are more similar to typical fall storms and will likely range from 40 to 60 mm. Strong winds gusting up to 80 km/h will also accompany this system.
Given the impacts from the recent atmospheric river and current vulnerability, rainfall warnings may be issued Sunday.
Also, there is an increased risk of landslide activity with the additional precipitation causing further slope destabilization.
