## extract

High Surf Advisory — Kuskokwim Delta Coast and Nunivak Island
Severity: Minor. Certainty: Likely.
* WHAT...
Kwigillingok, Kongiganak, and Kipnuk: Water levels as
high as 1.0 to 2.5 feet above the normal highest tide line.
Southwest winds 25 to 35 mph with gusts to 40 to 45 mph before
winds transition to west Tuesday morning, diminishing impacts.

Toksook Bay and Tununak: West winds 30 to 40 mph with gusts to
45 to 50 mph beginning Tuesday morning. Water levels as high as
0.5 to 1.5 feet above the normal highest tide line.

* WHERE...Kuskokwim Delta Coast, including Kwigillingok,
Kongiganak, Kipnuk, Toksook Bay, and Tununak.

* WHEN...From 1 PM Monday to 10 PM Tuesday.

* IMPACTS...There is potential for coastal erosion due to high
surf. 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.
