DESCRIPTION: * WHAT...Water levels 1.5 to 2.5 feet above the normal highest tide line. * WHERE...Along the Kuskokwim Delta coast, including the communities of Kipnuk, Kwigillingok, and Kongiganak. * WHEN...11 AM AKDT Monday through 6 PM AKDT Monday. * IMPACTS...Coastal erosion and flooding of low lying areas is likely. * ADDITIONAL DETAILS...Gale force southerly winds will lead to high water levels along the Kuskokwim Delta coast during the Monday afternoon high tide. Half an inch to 1.25 inches of rainfall are also forecast for the area through Monday afternoon, which may fill low-lying areas that normally take on water during lower level coastal flooding events, resulting in higher than normal water levels in addition to the onshore surge.

Next Topic: Cumulus Clouds
The final form taken by a growing cumulus cloud is the
cumulonimbus cloud, which is very tall and dense.
The tower of a cumulonimbus cloud can soar 23 km into the atmosphere, although
most commonly they stop growing at an altitude of 6 km.
Even small cumulonimbus clouds appear very large in comparison to other cloud types.
They can signal the approach of stormy weather, such as thunderstorms or blizzards.

Weather Topic: What is Drizzle?

Next Topic: Evaporation
Drizzle is precipitation in the form of water droplets which are
smaller than raindrops.
Drizzle is characterized by fine, gently falling droplets and typically does not
impact human habitation in a negative way. The exception to this is freezing drizzle,
a condition where drizzle freezes immediately upon reaching earth's surface.
Freezing drizzle is still less dangerous than freezing rain, but can
potentially result in hazardous road conditions.
