FLOOD WARNING IN EFFECT FOR THE SATSOP AND CHEHALIS RIVERS – FLOOD WATCH FOR GRAYS HARBOR COUNTY
Widespread river flooding continues, with most rivers cresting this (Wednesday) morning and afternoon, with the exception of the Chehalis River which will crest into later this week. The National Weather Service in Seattle reports If you come across a flooded roadway in your car, do not attempt to drive through it.
Due to large runoff from the heavy rains in the mountains Monday night and Tuesday, the Satsop River very quickly rose to a moderate flood stage level of 36 feet early last night. Flood stage is 34 feet near Satsop. The river has fallen quickly back to 34.4 feet. It is expected to fall below flood stage this morning. The Satsop River is still under a Flood Warning.
The Chehalis River
The Chehalis River has risen past Flood Stage of 21 feet at Porter. It is expected to crest at 22 feet @ 4pm Thursday, Nov 19. It will slowly recede below flood stage Friday night.
At 22 feet, the Chehalis River in Grays Harbor will flood pasture lands and many roads…including SR 12 between Oakville and Rochester. High tidal levels at Aberdeen will worsen flooding along the lower reaches.
Do not drive cars…vans…or trucks through flooded areas…this is the cause of most flood related deaths in Washington. Be alert for rapid changes and monitor developments by listening to NOAA Weather radio or other local media.
