Weather Alert in Alaska
Flood Watch issued September 2 at 7:41AM AKDT until September 7 at 10:00AM AKDT by NWS Anchorage AK
AREAS AFFECTED: NW Kenai Peninsula; Skilak Lake
DESCRIPTION: * WHAT...Flooding caused by the Skilak glacier-dammed lake release is possible. * WHERE...Skilak Lake and the Middle Kenai River near Skilak Lake and the Kenai River Downstream of Skilak Lake. * WHEN...Through Sunday morning. * IMPACTS...Kenai River level forecasts: Currently expecting the Kenai River to rise steadily at Skilak Lake outlet another 2 feet, cresting at moderate flood stage Friday or Saturday. At the Kenai Keys, expecting the Kenai River to rise another 2 to 2.5 feet, cresting just below moderate flood stage of 12 feet Friday or Saturday. Down river at Soldotna, expecting the Kenai River to rise steadily through week, cresting Saturday above bankfull levels near 12 feet. IMPACTS: Expect steady river level increases next 4 days on lower Kenai River. Flooding of low lying areas in the Kenai Keys area, boat dock issues and extended period of high water and bankfull conditions is likely. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. * ADDITIONAL DETAILS... - Skilak Glacier Dam Lake is likely releasing. This combined with recent significant rain in the upper Kenai River basin will cause Kenai river levels to rise steadily from the outlet of Skilak Lake to the mouth through the end of this week. Some uncertainty exists due to recent rain as to when the Skilak Glacier Dam lake began releasing which could impact the crest timing and height. Planned aerial reconnaissance of Skilak Glacier Dam Lake will confirm whether a release has taken place and the extent of any release. - Http://www.weather.gov/safety/flood

Next Topic: Cirrus Clouds
Cirrostratus clouds are high, thin clouds that form above
20,000 feet and are made mostly of ice crystals. They sometimes look like giant
feathers, horse tails, or curls of hair in the sky.
These clouds are pushed by the jet stream and can move at high speeds reaching
100 mph.
What do they indicate?
They indicate that a precipitation is likely within 24 hours.

Condensation is the process which creates clouds, and therefore
it is a crucial process in the water cycle.
Condensation is the change of matter from a state of gas into a state of liquid,
and it happens because water molecules release heat into the atmosphere and
become organized into a more closely packed structure, what we might see as
water droplets.
Water is always present in the air around us as a vapor, but it's too small for
us to see. When water undergoes the process of condensation it becomes organized
into visible water droplets. You've probably seen condensation happen before on the
surface of a cold drink!
