The flood watch for central Douglas County and the south central Oregon Coast went into effect Thursday and remains in effect through Friday, forecasters said.
"A strong slow moving storm will bring moderate to heavy rain to the region today into Friday. Flooding of creeks and small rivers is possible," forecasters said. "In addition, debris flows are possible across the steeper mountain terrain, and street flooding may impact city areas. More storms will bring additional rainfall later Friday through Sunday."
Forecasters predict the Coquille River will pass flood stage at Coquille and Myrtle Point on Friday night.
"A flood watch means that flooding is possible but not imminent in the watch area," weather service forecasters said. "Persons living along or planning activities near rivers and small streams in the watch area should continue to monitor the development of this weather situation."
