Middle Fork of the Salmon - big storm coming?

There's a storm hitting Idaho right now that has potential to blow the charts away. Check out this image of the North West River Forecasting Center's Middle Fork of the Salmon River gauge:


The Middle Fork of the Salmon, as far from what I can find, has never hit five-feet on the Middle Fork Lodge gauge in August. We'll just have to wait to see what happens... The NWRFC has been known to be off, but nevertheless things could get exciting.
