Stormtracker 2 breaks down what will happen if local rivers flood

This week, a "perfect storm" is brewing. All of the ingredients needed for flooding are happening right now: heavy rain, warmer temperatures and a lot of melting snowpack.

Our local rainfall totals are already surpassing the normal monthly averages. Another 1-2" is expected through Wednesday night. 

While some flooding will be minor, some flooding could be dangerous and damaging.

So, what if? What if our local rivers reach flood stage by Thursday morning? 

Stormtracker 2  is dedicated to answering that question over the next 48 hours as the rain increases, the snowpack melts, and river levels rise.
