The National Weather Service in Seattle is warning that recent heavy rainfall has led to an increased threat of landslides throughout Western Washington.
Between 0.75 of an inch and 2 inches of rain fell within a 24-hour period Wednesday and Thursday.
“The heavy rainfall adds to already saturated soil from rainfall over the past several weeks,” the alert stated. “The recent rainfall has put on extra pressure on soil instability… leading to an increased threat of landslides.”
The Weather Service also issued a flood watch for Grays Harbor, Lewis and Thurston counties.
