    Long Range Clues Through Late October

    9/27/2013, 10:00:10 AM

    Before I get to the long range, a series of significant Pacific fronts will impact the West Coast through Monday, bringing widespread heavy rainfall along with strong coastal and mountain winds.

    The map below shows the projected rainfall for British Columbia and the U.S. Pacific Northwest.

    Clearly, the heaviest rainfall will be over western Vancouver Island and into the Coastal Mountains. The west slopes of the Rockies will also see significant rainfall.

    The worst of the rain and wind will be on Saturday, followed by another batch over extreme southwestern B.C. later Sunday.

    Snow levels will be very high on Saturday (above 6,000 feet) then start to fall on Sunday.

    River flooding will be a concern for some areas downstream of the Coastal range through the weekend.

    ------

    Area of low pressure forming near Bermuda this weekend will track up into the Maritimes early next week.

    Looks like this will bring rain and some gusty winds to the region sometime Monday into Tuesday as it intensifies somewhat. However, I do not see this as being anything major for the region due to a lack of energy phasing and cooler water.
