The coastal flood threat is low to medium for Kwigillingok, Kongiganak, and Kipnuk (30 to 40 percent). The coastal flood threat is low (10 to 20 percent) for Toksook Bay and Tununak. * ADDITIONAL DETAILS...A developing low pressure system will drive a fetch of strong southwest winds towards the Kuskokwim Delta Coast early Monday afternoon, which will result in increased wave activity. Large breaking waves of 3 to 5 feet for the Kuskokwim Delta coast will continue into Tuesday morning, which will also coincide with high tide, enhancing coastal impacts. Southwest winds shut off later Tuesday morning for the Kuskokwim Delta Coast and attention then shifts to Toksook Bay and Tununak as west winds take over and the low moves inland. Strong west winds will bring in higher seas of 1 to 3 feet for Toksook Bay and Tununak. Conditions are on track to improve as the low moves farther inland Tuesday night. Additionally, periods of moderate to heavy rainfall will precede the advisory duration. PRECAUTIONARY/PREPAREDNESS ACTIONS... A High Surf Advisory means that high surf will affect the coastline in the advisory area, producing rip currents and localized erosion. -AM &&
