Special Weather Statement issued by Environment Canada at 1:30 PM PDT Monday 27 October 2014.

 --------------------------------------------------------------------- 
Special Weather Statement for: Metro Vancouver Greater Victoria Fraser valley Howe Sound Whistler southern Gulf islands west Vancouver Island inland Vancouver Island. Rain and wind tonight.  

Discussion- A typical October low pressure system will cross the BC north coast tonight. The path of the low has prompted wind warnings for most areas on the outer coastline north of and including North Vancouver Island. Tropical Storm Ana weakened and was absorbed into this system over the Pacific. Despite the tropical influence, this storm is not as powerful as the system that knocked out the power throughout the lower Mainland last week. The fast-moving cold front accompanying this low will cross the South Coast tonight. Wind warnings for sustained or steady winds to 70 km/h have been issued for East Vancouver Island and the Sunshine Coast. Wind gusts can be 25 percent higher than the steady wind forecast. The Pacific storm prediction centre does not expect to extend the wind warning to any other public forecast regions. Rainfall from this system will not reach the rainfall warning criteria in any region. However, given the tropical influence on the storm, rainfall may be intense at times...approaching 5 to 10 mm per hour and as high as 20 mm per hour across the mountain peaks. The public is advised to monitor future forecasts and warnings as warnings may be required or extended.
