Detailed Forecast


Synopsis: A weakening surface low will continue moving east into British Colombia, occasionally pushing frontal bands northward across the region this weekend. High pressure building over the Yukon on Saturday will intensify northerly winds through the northern inner channels, particularly during overnight and early morning hours. Early next week, a more robust low pressure center is projected to track northward along the eastern Gulf coast, causing an increase in winds and seas near Dixon Entrance.
