Weather Alert in California
Hydrologic Outlook issued February 19 at 1:26PM PST by NWS Medford OR
AREAS AFFECTED: Siskiyou, CA; Coos, OR; Curry, OR; Josephine, OR
DESCRIPTION: ESFMFR A moderate atmospheric river will likely bring periods of moderate to heavy rainfall later this weekend into early next week. The first frontal system is forecast to arrive late Saturday night into Sunday with multiple waves of precipitation continuing Sunday night through Tuesday morning. Preliminary estimates are showing widespread amounts of 4 to 6 inches along the coast with locally 8 inches in the favored coast ranges of Curry County. Amounts of 3 to 5 inches are possible in the Mount Shasta region and also other favored areas of western Siskiyou County. Small streams and creeks are likely to rise rapidly during this event with nuisance flooding and ponding of water on roadways during periods of heavy rain. Significant rises on main stem rivers and flashier creeks are also expected. Given that rivers are still running fairly low for this time of year, river flooding potential is a bit lower than usual, but there is at least a low probability of some flooding, especially in the Coquille Basin. While the exact scenario for the heavy rainfall and potential flooding remains uncertain, we will continue to monitor the forecasts and update accordingly. Flood Watches may be issued by the National Weather Service if this situation worsens.

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.

Next Topic: Fractus Clouds
Fog is technically a type of stratus cloud, which lies along the
ground and obscures visibility.
It is usually created when humidity in the air condenses into tiny water droplets.
Because of this, some places are more prone to foggy weather, such as regions
close to a body of water.
Fog is similar to mist; both are the appearance of water droplets suspended in
the air, but fog is the term applied to the condition when visibility is less than 1 km.
