...STRONG WINDS SUNDAY AFTERNOON THROUGH MONDAY MORNING ALONG THE
HILLSIDE, TURNAGAIN ARM, AND HIGHER ELEVATIONS...

Another Fall storm moving into Southcentral will cause strong
winds along the Hillside, Turnagain Arm, and higher elevations. At
times, gusty winds will impact lower elevations as well.

On the Upper Hillside, Turnagain Arm and higher elevations, winds
will rapidly increase during the day Sunday, gusting as strong as
70 mph from Sunday afternoon through late Sunday night. The winds
will diminish the most Monday morning, but may continue to gust
up to 50 mph along Turnagain Arm into Monday afternoon.

For the Lower Hillside, gusts up to 60 mph are possible late
Sunday afternoon into Sunday evening down to 1,500 ft elevation.
The winds will diminish Sunday night, as they turn northeasterly
for much of the overnight hours. Then on Monday morning when the
winds return to the southeast, gusts of 35 to 45 mph are possible
for much of the rest of the day.

For most of the event, Anchorage Bowl, Eagle River, and lower
elevation winds will be relatively light and variable in
direction. A stray gust can't be ruled out. Gusty winds are most
likely Monday morning into Monday afternoon, when gusts of 25 to
35 mph are expected.
