* WHAT...For the High Surf Advisory, large breaking waves of 2 to 3 feet above the normal high tide line. Water levels peak Tuesday afternoon. For the Coastal Flood Watch, coastal flooding possible at Hooper Bay. Water levels could reach up to 4 to 6 feet above the normal high tide line at Hooper Bay with the Thursday and Friday high tides. * WHERE...For the High Surf Advisory, Yukon Delta Coast. For the Coastal Flood Watch, Hooper Bay. * WHEN...For the High Surf Advisory, until 4 AM AKDT Wednesday. For the Coastal Flood Watch, from Thursday morning through late Friday night. * IMPACTS...For the High Surf Advisory, localized beach erosion may occur. For the Coastal Flood Watch in Hooper Bay, low lying areas may be inundated, including the airport access road. Shore erosion may occur. * ADDITIONAL DETAILS...Wind gusts will peak around 40 to 50 mph out of the south/southeast Tuesday. For the Coastal Flood Watch, the rest of the Yukon Delta coastline are expected see lower water levels in the 2 to 4 feet above the normal high tide line possible with the Thursday and Friday high tides.

What to do: If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. Precautions should be taken to protect property.

* WHAT...Visibility down to a quarter mile or less in dense fog. * WHERE...NW Kenai Peninsula, SW Kenai Peninsula, and Skilak Lake. * WHEN...Until 10 AM AKDT Wednesday. * IMPACTS...Hazardous driving conditions due to low visibility. Near to below freezing temperatures may lead to frost on bridges and roadways. * ADDITIONAL DETAILS...Areas of dense fog will affect portions of the Sterling Highway corridor tonight into Wednesday morning, including in and around Kenai, Soldotna and Cooper Landing.

What to do: A dense fog advisory means visibilities will frequently be reduced to less than one quarter mile. If driving, slow down, use your headlights, and leave plenty of distance ahead of you.

Between 4 and 7 inches of heavy, wet, snow fell across the Fairbanks Metro Area Monday. Warming temperatures Monday evening into Tuesday have caused portions of that snowfall to melt, creating many slushy areas of melting snow and pooling water. Overnight low temperatures Tuesday night into Wednesday morning are expected to fall into the upper teens to low 20s which will allow much of this slush to refreeze. Slick surfaces are very likely Wednesday morning as wet surfaces and small water puddles freeze. Areas of heavy, wet snow will also refreeze giving the slush a sturdier, more ice like texture. Travel may be impacted, especially during the Wednesday morning commute. Additional rain and snow showers are expected overnight Wednesday into Thursday with much lighter accumulations than Monday. Less than an inch of new snow is possible with only a few hundredths of an inch of liquid equivalent expected.

* WHAT...Southeast winds 30 to 40 mph with gusts up to 55 mph expected. * WHERE...Kuskokwim Delta Coast * WHEN...From 10 PM this evening to 10 AM AKDT Wednesday. * IMPACTS...Gusty winds will blow around unsecured objects and a few power outages may result. * ADDITIONAL DETAILS...Southeast winds will become strong and gusty by Tuesday night. Winds are expected to be strongest along the coast. Winds will begin to diminish Wednesday morning.

What to do: Winds this strong can make travel difficult. Use extra caution.

* WHAT...South winds 30 to 45 mph with gusts up to 65 mph expected. * WHERE...Eastern Alaska Range North of Trims Camp and Windy Pass. * WHEN...From 7 AM Wednesday to 7 AM AKDT Thursday. * IMPACTS...Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result.

What to do: Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.

* WHAT...Water levels of 1 to 2 feet above the normal highest tide line. * WHERE...Kuskokwim Delta Coast, including Kipnuk, Kwigillingok and Kongiganak. * WHEN...Until 10 AM AKDT Wednesday, highest water levels expected during each upcoming high tide through Wednesday morning. * IMPACTS...Nuisance flooding of low-lying areas. Coastal erosion is possible. * ADDITIONAL DETAILS...Steady south to southwesterly flow is expected to continue for the Kuskokwim Delta coastline through Wednesday morning as a series of low pressure systems track across the Bering Sea. Coastal erosion and perhaps nuisance flooding of low-lying areas will be possible with each upcoming high tide due to the persistent onshore winds. Maximum water levels will reach between 1 and 2 ft above the normal highest tide line, including in and around Kipnuk and Kwigillingok. A brief break in winds and elevated water levels is forecast late Wednesday, but a second round of elevated water levels and persistent southerly winds are forecast with the arrival of yet another front late Thursday into Friday.

ESFAFG Areas of concern are between Nome and Council, particularity streams and rivers draining the south aspects of the high elevation terrain of the Seward Peninsula. Rivers and streams in the Nome and Council area are already high following rainfall over the weekend. 1-3 more inches of precipitation are expected by the end of the week which will keep water levels high. No flooding is expected at this time, however residents living near local rivers and streams should be vigilant of the potential for ice in culverts and other stream passage structures to restrict flow resulting water flowing over roads in affected areas.
