Kelvin wave threatens coastal flood coverage in British Columbia
A coastally trapped Kelvin wave linked to a strengthening El Niño is moving north from Mexico's Baja peninsula and is expected to raise sea levels by roughly 6 to 12 inches where it reaches California, then continue up the Pacific coast toward British Columbia. That rise will elevate the baseline for every high tide and storm and could increase coastal storm surge impacts in weeks. In Canada most home and business policies exclude storm surge and coastal flooding, leaving many coastal households exposed despite one insurer, Co-operators, offering a Comprehensive Water product.

Context
A powerful El Niño is strengthening this year. Satellite-tracked Kelvin waves have moved north along the coast before. If the wave reaches British Columbia, baseline tides and storm surges could be higher for months.
