NWS Wilmington Online Snow Spotter Program

What Is The Online Snow Spotter Program?

The online snow spotter program is an effort to increase our real time snow reports during and after snow events throughout the winter. The goal is to receive quality snowfall reports from across our area while keeping the reporting and displaying procedures as simple as possible. Snowfall reports will be sent to our office through an online website. These reports will be updated on our webpage during snow events. They will also be included in our snow summaries that are sent out from our office periodically during and after snow events.

Along with measuring snowfall, spotters are asked to report icing due to freezing rain or freezing drizzle, and any time thunder is associated with snow or freezing rain.

How To Become An Online Snow Spotter

If you are already one of our spotters and have attended a storm spotter training session in the past two years, you can use your eSpotter account to enter snowfall reports. If you don't have an eSpotter account, but you are one of our spotters and have attended a storm spotter training session in the last two years, you can request one through the eSpotter website.

If you are not a trained spotter but would still be interested in becoming an online snow spotter, please email us for more information.

On certain occasions, we may call our snow spotters to solicit snowfall reports. We will only call at times you have given us permission to call. If you are a severe weather spotter, this information will be taken off the application you filled out at the training class. If you are an online snow spotter and are willing to be called for snowfall reports, please email us.

When And What to Report

We are most interested in snow amounts during and after an event. The program will key off of Storm Total Snowfall so be sure to report your Storm Total Snowfall (minus any snow already on the ground from previous events) when using the eSpotter program. If you want to report Sleet or Icing, report that amount in the Storm Total Icing section.

An event is defined as weather associated with the same low pressure or storm system, and may extend from a few hours to a few days. A break in precipitation of a day or more usually defines separate events. Other supplemental information that can be reported in addition to Storm Total Snowfall includes the following items.
  • 1" or more of snow per hour.
  • 1" or more of snow during the past 24 hours.
  • When first measuring 2", 4", or 6" of snow.
  • Snow depth.
  • Any freezing rain or freezing drizzle.
  • Any thunder or lightning associated with winter precipitation.
Location Information

Your reports may occasionally be posted to our website on a Google map (not to street level accuracy). If you are interested in having a more precise location for your report, please email us with your address. If you know your latitude and longitude, you can also include that if you like.

Reporting Without eSpotter

If for some reason you do not want to report through eSpotter, you are still welcome to call our office with snowfall reports using the procedures outlined in the spotter training classes. These reports will also be included in the snow summaries issued from our office.

How To Measure Snow
