Coastal Flood Watch & High Wind Watch Issued
Grays Harbor Emergency Management is urging all residents to be prepared for possible power outages due to downed tree limbs and power lines during two significant weather events approaching Friday and Saturday night.
High wind watch remains in effect from this 6pm tonight through 6 pm Saturday afternoon.
Winds are expected to reach 20 to 40 mph with gusts to 55 mph Friday night. Damaging winds, downed trees and power outages are possible.
The National Weather Service in Seattle has issued a coastal flood watch, in effect from Saturday afternoon through late Saturday night.
Wave swells of 26 to 29 feet are forecast to reach the coast Saturday night. The largest waves will arrive between 4 pm Saturday and 4 am Sunday.
Waves of this size can overtop levees and cause local flooding. Ocean Shores and Westport are most at risk of coastal flooding.
The largest waves are forecast to arrive during low tides. The highest high tides are predicted to occur at Westport at 8:53 am Saturday and 9:44 am Sunday, and the high tides are predicted to be around 9 feet. The largest waves will arrive when tides are forecast to be 7 feet or lower. Emergency Management told KXRO that “tides will not contribute much to any coastal flooding, the main effect will be from the giant waves themselves.”
Emergency Management asks that residents do not venture near downed tree limbs and power lines; do not operate a portable generator indoors or near open windows or doors; use extreme caution while driving since heavy rain will be associated with the storms and roadway flooding could occur making driving extremely hazardous.
