Volunteers of all ages are needed to report valuable rain, hail, and snow measurements.
The National Weather Service relies on volunteer weather observers that take precipitation
readings in their own backyard. Many observers are needed because precipitation is highly
variable. You can help and anyone can join! All you need is a rain gauge as shown below
and internet access
