4. 911-Local/county dispatch office: These reports are then relayed from dispatch to our office; however there may be a delay in this procedure depending on how busy the dispatch center is. Call 911 for emergency services.


5. E-mail: for sending storm pictures and videos. This should be used for storm histories and “after the fact” events.


Here is how to make a good storm report:

  • WHO
    Give your name/spotter #  and any affiliations you may have (i.e. member of a spotter organization, amateur radio club, sheriff's department, etc).
  • WHAT
    Provide a detailed description of what happened, including any damage, measurements, injuries, or fatalities. Mention how you arrived at your values. For instance, don't just say there was "nickel size hail", say whether you measured this with a ruler or estimated.
  • WHEN
    Try to give as precise of a time as possible for the event occurrence.
    Give as exact of a location as you can when reporting. Try to give a distance to the nearest tenth of a mile from the nearest town, village or city. Cross streets can be very valuable to include in your report, especially if you are in an urban area. Be aware of where you are! Also, be sure to distinguish between where YOU are and where the EVENT is occurring.
    "My name is Joe Public, spotter number W999.  I measured quarter sized hail with a ruler at 4:46PM about 1.5 miles west of Greeley. Also, at the same time I can see a rotating wall cloud about 2 miles to the west of my location." is the U.S. government's official web portal to all federal, state and local government web resources and services.
