CoCoRaHS March Madness 2018 results as of March 16th (week three) - The Halfway Point

"CoCoRaHS March Madness 2018” (our friendly annual recruiting competition between our CoCoRaHS states to see how many new volunteer observers we can recruit during the month of March) comes to the end of it's third week.

As of Friday morning, the "traditional count" category (total number of new observers) has South Carolina (94) still in first, followed by Minnesota (61), Wisconsin (50), North Carolina (49), Georgia and California (39).

In the "population weighted" category, North Dakota (34.20) keeps the lead, followed by South Carolina (20.32), Minnesota (11.50), Nevada (10.00) and Wisconsin (8.79).

To view this week's standings as of March 16th and learn more about our contest, visit our March Madness webpage by clicking here: "COCO MARCH MADNESS PAGE" . We will post an ongoing update of points by state each Friday/Saturday via our “Message of the Day”. Final results posted on April 1st.

A reminder that this year we are challenging everyone to sign-up a friend or relative as a CoCoRaHS observer during the thirty-one day competition.

Good luck to your state!

The "Total SWE Monday" -- Please continue to report your Snow Water Equivalent measurements throughout the month of March

The National Operational Hydrologic Remote Sensing Center utilizes CoCoRaHS reports of precipitation, snowfall, snow depth and the water equivalent of the snow on the ground every day. CoCoRaHS data provide critical "Ground Truth" information that can improve the skill of their products and models. This will improve the accuracy of flood forecasts in the weeks and months ahead.

Their guidance to us has been that if you can only report one day a week it’s best to all report on the same day. Monday was chosen:

"The analysts at NOHRSC prefer a Total Snow Water Equivalent (SWE) observation taken once a week on Monday. The simple reason is that digging cores every day ruins your sample snowfield area (unless you have a big yard or open fields nearby).

A flood of Monday morning SWE reports gives us a better picture of the overall snowpack instead of a few scattered results trickling in throughout the week. Daily total SWE would be great, but let's make "Total SWE Monday" a habit.

(Note: If you have the room, more frequent observations are appreciated, especially when conditions are changing. For areas that only infrequently get snow, there is no need to wait for Monday -- report SWE whenever you have the chance). For instructions on how to take core samples and report the snowpack SWE, please view our on-line training materials on snow: Training Slide Shows or watch the YouTube short animation on: SWE.
