CHEHALIS STILL RISING – SATSOP RECEDING

Flood Warning, Wind Advisory, High Wind Watch,

Coastal Flood Watch and Flood Watch Issued

The National Weather Service in Seattle has indicated numerous weather patterns will continue to impact the region through the weekend. Strong winds and rain can be expected throughout the week. Rainfall over the last 4 days ranged from 4” – 10” at the coast, and 2” – 7’ inland. Mountain ranges have received very heavy rainfall producing moderate to major flooding issues on many area rivers(Satsop & Chehalis).

Many regional landslides have occurred and continuedrainfall will contribute to landslide possibilities into next week.

The Weather service also alerted us to potential Coastal Flooding Wednesday through Thursday.  Low atmospheric pressures, the Chehalis River above flood stage and a storm impacting us Wednesday into Thursday will heighten the flooding impact to the region. High astronomical high tides could reach 2-3 feet above the predicted levels. (4 foot anomalies are possible).Large surf will occur along our coast Wednesday night andThursday, creating coastal flooding and severe erosion and prevent the flood waters from flowing to sea. Flood impacts will be dependent upon the time of high tide and the arrival of the storm.

COASTAL FLOOD WATCH -

IMPACTS TO ABERDEEN, WESTPORT AND OCEAN SHORES

A Coastal Flood Watch is in effect from 9 am today through Thursday afternoon.  The strong and high surf along the coast Wednesday and Thursday will prevent flow from the Chehalis River into Grays Harbor increasing flooding risk in the Aberdeen area. The astronomical tides, storm surge and atmospheric pressures will contribute to 2-3 feet or higher tidal levels above the projected tides in all coastal areas, (4 foot anomalies are possible).

Coastal flooding will occur during the times of high tideWednesday & Thursday.
