Maritime Soaker from Sean

11/08/2011, 8:04:27 AM

I am home from work today with a case of bronchitis, so this will be brief as I am certainly in no shape to do a video!

Subtropical Storm Sean will be drawn northward then northeast over the next few days as it gets absorbed by a sharp cold front coming in from the west.

Both the Canadian and NAM models keep Sean intact as it drives up through the Maritimes early Saturday with heavy rain and strong, tropical storm-force winds along and east of the center.

The more reliable GFS and European global models basically split Sean and merge part of it with the front, leading more of a rainstorm with most of the rain on the eastern side of the slowly approaching front. Southerly winds in this case will still be strong along the Nova Scotia coast and over western Cape Breton.

Due to the time of the year, cool water temps and high wind shear I lean toward the weaker GFS/European model. However, with all this tropical air being drawn northward there will be flooding issues.

The bulk of the rain will come late Thursday night through the first half of Friday.
