Very warm weather will cause creeks to rise!

Black Eagle Falls Friday afternoon.

The warmer weather is causing snow pack to melt and creeks and streams to rise. This photo I took this afternoon shows the Missouri full but little water going over the top of the dam. The National Weather Service has put out a special statement about the rapid melting and runoff. I have placed their statement below, please be careful if you are going to be outdoors around creeks and streams, or areas that flood easily.

Our temperatures for the weekend stay in the mid to upper 70’s with plenty of sunshine.  By Monday we could see an 80 degree day. It really doesn’t cool off much Tuesday and the rest of the week with highs in the upper 60’s to low 70’s, so that is the concern for rapid runoff.

I hope you have a great weekend, it’s nice to be able to get outdoors and take care of those long put off chores!
