LOCATION/KNOWN FLOOD AREA (KFA)*: Lower Kuskokwim, Akiak down to the mouth

PRODUCT TYPE: Warning

EXPIRATION TIME: Sunday night

PRIMARY CAUSE: Storm Surge

BASIS:
	A strong storm system will track just to the north of the Y-K Delta on Sunday.  Strong SW winds 
        and associated up river storm surge will correspond closely to Sunday's high tide at lower Kuskokwim 
        communities, leading to very high water levels, rapid bank erosion, and flooding.   

IMPACTS:
	Residents reported flooding and rapid bank erosion during Friday and Saturday's high tide at Akiak, Napakiak, Kasigluk,
        and Tuntutuliak.  At Napakiak, a village elder reported the bank in front of the school was eroding rapidly and was
        only about 6 ft from the structure.  Water during Friday and Saturday's high tide had inundated most low spots in
        the village, including the low spot in the road to the dump.  Water levels are reported to be higher than during breakup
        flooding this May.  A resident in Kasigluk reported water was encroaching on low lying residences.  Water levels there
        were the same as seen during this year's breakup, and only a few inches below that during Merbock.  
        In Tuntutuliak, a resident reports the village has been flooding for the past 4 days.
     
        Based on tidal and storm surge forecasts, river levels will be the highest during Sunday's high tide.  At Bethel, water
        levels at the Brown's Slough gage are expected to approach flood stage at 8.5' Sunday afternoon, still lower than seen
        during Merbock, where the gage crested at 9.48'.
