A huge chunk of Alaska's western coastline is now under flood and storm warnings, as forecasters warn that the remnants of a Pacific typhoon could bring seas up to 54 feet and winds up to 75 knots (86 mph) to the shore this weekend.

"Typhoon Merbok has transitioned into a historically powerful Alaskan storm in the Bering Sea," the National Weather Service said on Friday. "Significant, damaging high winds and storm surges are expected to slam into southwestern Alaska, especially along the southern Seward peninsula."
