A series of storms will cross the northeast Pacific through early next week, the National Weather Service in Portland advises. These storms will send significant westerly swells toward the Pacific Northwest coast resulting in periods of high surf activity well into next week. Surf up to 29 feet in height is forecast for the Long Beach Peninsula for this Friday.
Additional events are expected Sunday through Tuesday. Details remain very uncertain about the latter events and will be refined as they draw nearer.
The weather system early next week is expected to bring heavy rain to the Pacific Northwest. While the details are uncertain, there is potential for 2 to 5 inches of rain in Southwest Washington and Northwest Oregon Monday night and Tuesday, with heaviest amounts in the Willapa Hills, the North Oregon Coast Range, and the west slopes of the Cascades.
Sharp rises are likely on rivers draining these areas, and minor flooding is possible Tuesday and Wednesday.
The timing and location of heavy rain for this storm remains uncertain. If conditions warrant, watches or warnings for specific areas or rivers will be issued.
