Today is the end of the 2021 water year (WY) with a total rainfall of 36.42 inches at my CoCoRaHS station (OR-DG-22). The 30 year average here is 42 inches. For the month of September I recorded 2.86 inches, compared to the 30 year average for the month of 1.17 inches.
Here is a look at the last 5 years:
WY 2017 = 60.93 inches
WY 2018 = 33.71 inches
WY 2019 = 48.75 inches
WY 2020 = 33.64 inches
WY 2021 = 36.42 inches
5 year average = 42.69 inches
It will interesting to see what the new 30 year average will be as they are calculated every decade. The present 30 year average is based on rainfall from 1981 to 2010. New averages from 1991 to 2020 are due at the end of this water year. This is accessible through the PRISM Portal.
The forecast call for a wet and cold fall and winter in the Pacific Northwest under La Nina conditions.
I'll believe it when I see it.
Thank you Mike, this information is very helpful, and helps me to keep things in perspective. I appreciate your weather forecast of a wet and cold fall and winter. I had hear La Nina was back, but hadn't heard if that was good news for us, as we so desperately need rain and snow. in preparation, we are tucking in our 8+ cords of wood.
