Surface Analysis 1800 UTC 4 Jan

Short term… A strong storm will pass through the gulf of
maine tonight bringing a large area of hurricane force gusts
to the outer waters. Casco bay and penobscot bay remain at
storm force as some of the strong gusts are likely to mix down
even along the shoreline.

Long term… Cold and windy conditions will likely lead to
freezing spray through Sunday morning. Winds gradually diminish
and finally fall below advisory levels at least briefly on
Sunday, but will increase again on Monday as another trough
moves through.
