ESFMFR An atmospheric river arrives Thursday night and persists through Friday, bringing another round of moderate to heavy rain. Rainfall 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. The exact scenario for flooding remains uncertain. This product will be updated as necessary. Watches and warnings may be issued by the National Weather Service if this situation worsens.
