Amazing Rain Intensity
An hour ago, an amazingly intense line of thunderstorms passed through central Puget Sound. At my house there was nearly .4 inches over 15 minutes--and my gutters did not do very well with that volume of water. Take a look at the radar--you can see areas of red...those are intense rainfall areas...and one went over my house--and there wasn't any hail, which is usually associated with such high values. Just amazingly intense rain with big drops. An image from the new Rainwatch system (which will become public soon) is show below as well...many lowland locations have gotten 1.5-2 inches over the last day. Some areas received over two. Scattered urban flooding has occurred. No issue with the Green River--early in the season and its watershed did not get sufficiently large amounts of precipitation for any concerns.
