Measuring and Reporting Snow to the National Weather Service

The National Weather Service needs your help!  During snow storms, your snow depth measurement, especially if you live in a rural area, is valuable information for determining the impact of the event and accuracy of our forecasts.  When it snows or sleets, we encourage you to find a simple yard stick and take snow depth measurements every 6 hours -- or more often if melting has already begun to occur.  Please report your snow depth (in inches) using our Storm Report Form.  Your report will be immediately sent to and viewed by a NWS forecaster.  Also feel free to share your reports and pictures with us on our social media pages.

Taking accurate snow observations is very important. Please click the following slides for a short primer on how to correctly measure snow and sleet depth.

Report your snow depth measurement on the Storm Report Form
