Weather Alert in Alaska
Special Weather Statement issued August 28 at 4:05AM AKDT by NWS Anchorage AK
AREAS AFFECTED: Northern Copper Valley; Western Copper Valley; Central Copper Valley; Ernestine; Southern Copper Valley
DESCRIPTION: A frontal system moving into Southcentral will usher strong and gusty southerly winds into the Copper River Basin and Valley starting late this morning. The strongest wind gusts will range from around 35 mph to near 55 mph, with the strongest gusts focused along the Copper River Valley north of Kenny Lake and along the Richardson and Glenn Highways north and west of Glennallen. Winds will begin to diminish tonight into Friday morning as the front pushes to the east. People are urged to secure loose objects that could be blown around by the strong winds and use caution while traveling. Winds could coincide with periods of moderate rain, potentially making driving difficult at times. Trees are still fully leafed and will be unusually vulnerable to damage from the strong winds. Localized power outages will be possible due the potential for strong winds to bring down tree branches onto power lines.

Cumulus clouds are fluffy and textured with rounded tops, and
may have flat bottoms. The border of a cumulus cloud
is clearly defined, and can have the appearance of cotton or cauliflower.
Cumulus clouds form at low altitudes (rarely above 2 km) but can grow very tall,
becoming cumulus congestus and possibly the even taller cumulonimbus clouds.
When cumulus clouds become taller, they have a greater chance of producing precipitation.

Evaporation is the process which returns water from the earth
back to the atmosphere, and is another crucial process in the water cycle.
Evaporation is the transformation of liquid into gas, and it happens because
molecules are excited by the application of energy and turn into vapor.
In order for water to evaporate it has to be on the surface of a body of water.
