No, Redoubt is over 200 miles away from Valdez. The Cook Inlet is separated from the Prince William Sound by the Kenai Peninsula; they are very separate bodies of water.

Rumor going around Soldotna is they now have evacuated the western part of the inlet and capped the wells. Air filters are flying off the shelves.
