The National Weather Service in Anchorage has issued a High Surf Advisory, which is in effect from 10 PM Tuesday to 10 AM AKDT Wednesday. * LOCATION. Primarily for the southern Bristol Bay coastline from the mouth of the Kvichak River to Port Heiden, including the communities of Naknek, Egegik, and Pilot Point. High surf is possible but less likely from the mouth of the Kvichak River west to Cape Newenham. * WINDS AND WAVES. Southwesterly winds of 30 to 40 mph are expected, with gusts as high as 50 to 65 mph. Waves up to 10 feet breaking on the shoreline. * TIMING. Strong southwesterly winds peak between about 10pm Tuesday and 6am Wednesday, around the same time as high tide. The worst conditions will occur around or shortly after midnight, then improve through the early morning hours on Wednesday. * IMPACTS. Winds and waves are forecast to bring about a 4 to 6 ft surge on top of the high tide, which may inundate or move property along the shoreline. Coastal erosion during high tide is likely. * ADDITIONAL DETAILS. While the strongest winds are expected for the southern Bristol Bay coastline, a long duration of south to southwesterly winds from Tuesday morning through evening could also lead to high surf along the northern Bristol Bay coastline, including the communities of Dillingham and Togiak.
