TIMBERLINE LODGE -- A mix of heavy rains and dramatic snow melt over the weekend raised river levels quickly and created dangerous flooding on Mt. Hood that locals said they had never seen to that extent before.

KGW Chief Meteorologist Matt Zaffino pointed out a startling statistic that had Mount Hood National Forest rivers gushing.

The North Fork of the Bull Run lost the equivalent of 7.40 inches of water from snow melt, he said. Combine that with the 9.51 inches of rain at Timberline and you have almost 17 inches of rain.

Yes, the two locations are about 20 miles apart, he said, but it's still a lot of water, and the Sandy and Salmon Rivers responded accordingly, no matter how you add it up.

While the mountain was inundated, Zaffino said, interestingly, Portland airport was only about a half-inch above normal with 3.38 inches for January rainfall to date. It's conceivable that it will end the month with below average precipitation.
