...Heavy rain expected in Coos, Curry, Douglas, and Josephine
counties causing quick rises on area streams, creeks and rivers...

An atmospheric river arrives tonight and persists through
Friday, bringing a round of moderate to heavy rainfall. Rain
amounts of 2 to 4 inches are expected, with the highest amounts
likely in Curry County. This is a slight decrease in rainfall
amounts as the focus of the atmospheric river lingers a bit longer
to our north before arriving in Douglas County and farther south.

Despite the slightly reduced rainfall expected, small streams and
creeks are still likely to run high and could result in nuisance
flooding along with ponding of water on roadways during periods of
heavy rain. Significant rises on mainstem rivers are expected, but
the overall concern for widespread river flooding is low at this
time due to antecedent dry conditions and minimal snowpack. We will
be monitoring rivers in the Coquille and Umpqua Basins for flooding
potential.

This product will be updated as necessary. Watches and warnings may
be issued by the National Weather Service if this situation worsens.
