What weather should I check between Seattle and Vancouver?

Check coastal rain, fog near lowlands, and wind near exposed water crossings along the full I-5 and BC Highway 99 corridor. Pacific Northwest systems can make timing useful for rain intensity and visibility. Refresh the forecast close to departure and verify official road information.
