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, we encourage you to find a simple yard stick and take snow depth measurements every 3 to 6 hours -- more often if conditions are rapidly changing.  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.

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