Coast Guard's frantic search for five missing people after fishing boat capsizes in Alaska

The Coast Guard is frantically searching for five people who went missing after a fishing boat capsized in icy Alaskan waters.

The vessel overturned near Point Couverden, a cape near Hoonah on Sunday.

Officials received a mayday call at 12:10 a.m. from the crew aboard the 50ft fishing vessel Wind Walker reporting they were overturning. 

An MH-60 Jayhawk helicopter was scrambled from the Coast Guard's Sitka station, along with a 45ft boat from Juneau.

A passing ferry overheard the broadcast and offered to assist in the search . The AMHS Hubbard was first to arrive on the scene.

Seven cold-water immersion suits and two strobe lights have been located in the water in the search area.

Officials said they had received reports that five people were aboard the vessel, however the number could change. 

Point Courverden is around 24 miles south west as the crow flies from the Alaskan capital of Juneau.

Rescuers are battling six foot seas and icy 27 degree conditions amid the search.

There is a winter storm warning in place which has already seen large amounts of snow deposited in the area as well as howling 50mph winds.

The stormy conditions are expected to continue until Monday morning when the warning expires. 

Anyone with information about this situation should contact Coast Guard Sector Southeast Alaska at 907-463-2980.
