2024-12-14 · South Washington Coast, Washington

Event narrative

Several highways and roads in the low-lying areas around Willapa Bay flooded due to the combination of high astronomical tides, large surf, and rainfall. A surge of 2.4 ft MLLW was calculated by subtracting the astronomical tide height from the observed total water level from the NOAA NOS Toke Point Tide observing station. Highway 101 flooded in three locations resulting in closures that impacted the city of Raymond. The South Bend Highway was closed west of Naselle near the State Route 4 intersection. Water and rocks across State Route 105 impacted travel near mile marker 20. Tokeland Penn near Toke Point had 3 ft water across it with 12 to 18 inches of water observed across Lower Peter Street.
