WALLA WALLA — A combination of melting snow in the mountains and widespread rain expected Wednesday have prompted a flood watch for Central and Southeast Washington and Northeast Oregon.
According to the National Weather Service, several weather systems will be moving through the region over the next few days with periods of heavy rain. The heaviest rain is expected Wednesday night and again Thursday night.
Rain amounts through this period are expected to reach 1 to 3 inches along the east slopes of the Washington Cascades with 1 to 1.5 Inches possible over Northeast Oregon.
Streams and creeks that have already been running high due to mild conditions will see rapid rises Wednesday night and minor flooding is possible with a break early Thursday and rises again Thursday night. Large rivers will also see rises but are not expected to flood at this time.
Daytime temperatures will be in the 50s for most locations and snow levels will be 5,000 to 7,000 feet. The weather fronts will also create breezy to windy conditions Wednesday into Thursday.
