ANCHORAGE, Alaska (AP) — Flood waters are receding in parts of western Alaska battered by the worst storm in a half century. The storm left behind debris flung by powerful Bering Sea waves, the remnants of Typhoon Merbok, which was weakening Sunday as it moved north from the Bering Strait into the Chukchi Sea. Officials say the storm caused widespread flooding and damage along 1,000 miles of the Alaska coastline. Several communities reported homes were knocked off their foundations by the force of the incoming water. The massive storm also influenced weather systems as far away as California, where rare late-summer rains drenched the northern part of the state.
