Volunteer Observers Needed (Blaine, Canadian, Kingfisher, Garfield, Logan, Payne counties)

The short and quick of it, this network still needs observers everywhere!   Many thanks to the dedicated observers that are already spread across the area.  However, as the map here shows, there are some large holes to fill!  The stations painted green on the map are active stations.  Red stations are those that have either been closed out, or haven’t submitted an observation in several months.

As the coordinator for the above listed counties, I am particularly interested in new volunteers in those areas.  If you need more information or help signing up, please contact me at david@okweatherwatch.com

The CoCoRaHS network is needing observers nationwide.  Information on how to sign up can be found at http://www.cocorahs.org
