The National Weather Service has upgraded a Flood Watch to a Flood Warning in southwest Oregon and northern California.
The Weather Service Station in Medford reports the Flood Warning for Josephine, Jackson, Curry, Coos and Siskiyou counties is in effect through Friday at midnight.
Flooding caused by excessive rainfall and snow melt is expected across the region. That includes flooding of local rivers, creeks and streams as well as low-lying and flood-prone locations.
According to satellite estimates, between one and six inches of rain has already fallen in the area. Additional rainfall amounts of three to seven inches are possible in the Warning zone.
Some higher-elevation areas will receive snowfall that will switch over to rainfall. Rain can melt the snow and cause a higher amount of runoff than rainfall alone.
Weather experts warn motorists to turn around and don't drown when encountering flooded roadways. Most flood deaths occur in vehicles.
