...FLOOD WATCH IN EFFECT FROM FRIDAY MORNING THROUGH MONDAY
MORNING FOR KENAI LAKE AND THE KENAI RIVER FROM COOPER LANDING TO
SKILAK LAKE...

The National Weather Service in Anchorage has issued a

* Flood Watch for Kenai Lake and Kenai River from Cooper Landing
  to Skilak Lake.

PRIMARY CAUSE: Glacial Lake Outburst from Snow glacier dammed
lake.

TIMING: From Friday morning through Monday morning.

REASON FOR FLOOD WATCH:
The Snow glacier dammed lake is releasing at this time. Water
levels on the Snow River are steadily rising and are reflective of
previous outburst events. Expect a significant water level
increase on Kenai Lake through the weekend.

Water will likely rise to the point of flooding the Primrose
campground and other low lying areas by Friday afternoon. Water
may continue to rise on the Kenai Lake and Snow and Kenai Rivers
through the weekend and early next week.

Water levels on the Kenai River below Skilak Lake will likely see
a more moderate increase to bankfull conditions by early next
week.

There is considerable uncertainty of water volumes released and
drain rates during glacial dammed lake outbursts. This particular
event is anticipated to coincide with several days of
precipitation. Please check back for updates at the Alaska-Pacific
River Forecast Center website: www.weather.gov/aprfc/

EXPECTED IMPACTS:
Low-lying areas above Skilak Lake are anticipated to see moderate
flooding at the culmination of this event.

COMMENTS:
This product will be updated daily or sooner if conditions warrant.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A flood watch means there is a potential for flooding.

You are encouraged to closely monitor this weather situation.
Preparation for this potentially dangerous weather event should
begin now.
