- Reports between 6:00 and 10:00 am are preferred, but not mandatory.

CoCoRaHS is Volunteer-Friendly!What if I’m not home?
- Have a friend check your gauge for you.- Or, report a “Multi-Day Accumulation.”- Or, just report “Missing.”
A dense network makes a handful of “missing” observations more acceptable.
