Washington Snow Survey Program

Finally we get runoff. Unfortunately due to very high temperatures, if only for a few days, significant flooding was experienced on a few streams in the state. Below average precipitation during May most likely helped curtail worse flooding. Even with the mercury pushing near triple digits the average temperatures for May remained near to below normal except in the Okanagan and down through the Yakima area where above normal temperatures prevailed. Record high snowpack remains in some basins as well; driving streamflow forecast projections higher than previously thought. Weather forecasts for the next three months are calling for continued cool temperatures with best chances of near to slightly below average precipitation. This will be the final Water Supply Outlook Report published for this water-year.
