CWOP SNOW SIGN-UP

CWOP Snow Sign Up (US only)

Snow observations from your location can be useful to others who may have had snowfall from the same storm. These data are also of interest to NOAA. Your snow data will be included in the MADIS data set and distributed to user organizations including the NWS. Before signing up to do this public service, read snow project description and snow measurement instructions to be sure you understand it.

CWOP members can sign up to send snow data. If you are not yet a CWOP member but would like to contribute snow data, please click here.

Entering and viewing snow observations

To enter CWOP snow data, use the snow data entry form. To see any of the snow data, use the NOHRSC snow data viewer. A good help page can be found here.
