Flood watch for Grays Harbor County today and Friday


A flood watch is in effect from Thursday afternoon to Friday afternoon for Grays Harbor County and much of Western Washington. The watch was issued by the National Weather Service in Seattle late Wednesday.

A flood watch means condidtions are favorable for flooding but flooding is not imminent or occurring, the service said.

The heaviest of significant rainfall is expected from the Olympic range eastward. Potentially one to two inches of rain, with amounts of up to four inches in the Cascades could fall during this period. “Thunderstorms on Thursday could produce rain rates of an inch in one hour or less,” the service said.

A short, intense rain could cause flash flooding and overwhelm storm drains which could lead to flooded roads. Excessive amounts of rain could lead to urban and small stream flooding. The service said to “expect significant rises on area rivers but flooding is unlikely.”
