A storm system will bring in heavy rainfall at times over the Olympic Mountains Wednesday and Thursday. Total precipitation amounts will range from 1 to 3 inches, though rainfall amounts will be highly dependent on the convective nature of this storm system and where heavier showers set up. Snow levels will stay above 8000 feet on Wednesday before falling to 3500 feet on Thursday, increasing the potential for river flooding. River flooding remains possible and we will continue to monitor the potential for river flooding during this period. $$ 15
