Tropical depression Ana headed our way


Special Weather Statement updated by Environment Canada at 4:45 am PDT Sunday 26 October 2014. -

The remains of Tropical Storm Ana will move to lie off the BC coast late Monday and Tuesday. Wind warnings have been issued for North Vancouver Island, Central Coast - Coastal Sections and haida gwaii. These warnings may need to be extended to the South Coast later today or tonight as southeast winds near the coast are expected to strengthen Monday night. There will likely be heavy rainfalls as well with 50 to 75 mm possible through Monday night and Tuesday.




Ana has completed the transformation into an extratropical cyclone. Due to strong southwesterly shear...the diminishing cold cloud tops are located northeast and east of the nearly exposed low level center...while cold air stratocumulus clouds are seen wrapping in toward the center from the north and west. 


8pm Monday night


Additionally...the main cloud shield began to resemble a baroclinic Leaf earlier in the night...indicating the transition was well underway at that time.

The initial intensity for this advisory is set at 50 kt based
on a blend of the available subjective and objective satellite
