Hydrologic Outlook issued February 20 at 1:44PM PST by NWS Medford OR

Summary: 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
