(SitNews) Ketchikan, Alaska - Wrapping up the meteorological summer season (June-August 31), what is there to say about August other than that it was a soaker.

You may ask, where is all of this rain coming from? The phrase that we became all too familiar with here in Southeast Alaska is: “there is a low in the Gulf."

Throughout the month of August, several low pressure systems moved into the Gulf of Alaska bringing wave after wave of weather fronts across the Panhandle. On August 9th, one of the stronger lows caused several impacts throughout the panhandle. High wind along with flood watches and advisories were issued for portions of the panhandle.
