Training Resources

The National Weather Service (NWS) and emergency managers host spotter training classes across central Iowa each spring.  Training is delivered by a combination of "in-person" spotter training classes scattered across central Iowa and webinar-based distance learning classes.  In-person spotter training classes are offered in larger cities and towns and in several rural counties and small towns.  Every county in the NWS, Des Moines, County Warning Area (CWA) has a "in-person" spotter training class at least every other year.  To supplement "in-person" training, the NWS conducts weekly webinars using Join-Me internet-based distance learning webinars during spotter trainnig season.  All webinars are open to all spotters!  One "advanced" spotter class is also offeredl. The advanced class will build on what is taught in the regular class. It is intended for those who wish to do mobile spotting and desire a deeper understanding of meso-scale and storm scale meteorology as it relates to storm spotting. 

In addition to live National Weather Service spotter training presentations, there are several on-line training opportunities available.

       On-line spotter training resources

  • Spotter Data Quality Training
  • Spotter Reference Cards - Download PDF spotter reference cards to use while spotting!
  • 2014 Course Notes and Registration Info
  • Spotter's Field Guide - large PDF which may take a while to download (Updated for 2012)
  • Wind and Hail Reference Table
  • Spotter Cards ( .pub | .pdf | .doc )
  • Spotter Do's and Don'ts
  • National Weather Service, Des Moines, Spotter Training DVD - The DVD is available for emergency managers, fire departments and amateur radio clubs within the WFO Des Moines County Warning Area. It is ideal for groups who cannot attend a regular spotter training class,  but still need training.   To request a Spotter Training DVD, please e-mail Jeff Johnson at jeff.johnson@noaa.gov. Please include your name, agency/department/group and your address.  The Spotter Training DVD is NOT available for individual spotters or the general public.
  • On-line SKYWARN Spotter Training - This course was developed by COMET which is a program that  supports, enhances and stimulates learning about atmospheric and related sciences.  It was not developed by the National Weather Service office in Des Moines.  The on-line course does NOT replace the need to attend a National Weather Service spotter training class. 

    The goal of the course is to provide baseline training for all spotters through multiple modules covering the procedures for spotting (including communication and spotter report criteria) and safety considerations for all hazards. As of September, 2011, there were two modules available including the Role of the SKYWARN Spotter and SKYWARN Spotter Convective Basics.  Students must register on the MetEd website to take the course.

    To register as a National Weather Service, Des Moines, IA, please follow the instructions below under Severe Verification Network.  This is in addition to registering as a SKYWARN Spotter at the end of the on-line course.

Central Iowa Spotter Networks

Severe Verification Network

The Severe Verification Network is ideal for anyone who wants to report severe weather directly to the National Weather Service!  There are over 3000 spotters in the Severe Verification Network (SVN) in all 51 central Iowa counties served by the National Weather Service in Des Moines.  Benefits of belonging to the network include easy access to the severe weather operations center at the National Weather Service, Des Moines, IA via a private 800 spotter line, an occasional spotter newsletter (for those who provide an e-mail address), your home location which is a database and used to identify your location information already in the system and a notification reminder of the upcoming spotter training season. 

Interested in joining the SVN network?  Here's how:

    • You must be 16 years or older
    • Attend a spotter training class or complete the COMET SKYWARN Spotter Training cours
  • Register online (NEW and preferred method) - Visit the Mid-Iowa Skywarn Association website at http://www.midiowaskywarn.org.  Note the "Action items for spotters" box a top the page, selecting the "Register as a spotter or update your Information" link.

  • E-mail your registration information directly to the NWS Des Moines Spotter Team via the spotter admin e-mail account (dmx.spotteradmin@noaa.gov).  Information should include your name, residence and mailing address (if different) as well as at least one phone number where you can be contacted.


Emergency Management Spotter Networks

These groups contain fire personnel, law enforcement, local amateur radio groups and local citizens. They are managed and maintained by the county emergency manager, or other designee.  These spotter groups are highly variable depending upon the county.  Most reports are sent to the NWS via the 911 Center Dispatcher, or by county EOC. A spotter can belong to the SVN and county spotter network!

Amateur Radio Spotter Networks

There are numerous SKYWARN amateur radio spotters across central Iowa.  Amateur radio spotters can reach the amateur radio net controller at WFO Des Moines providing the linking systems are operational.  During severe weather, amateur radio net controllers operate from the National Weather Service in Des Moines.  Net controllers receive spotter reports from amateur radio spotters from across central Iowa. Amateur radio is an excellent way to send severe weather reports real-time to the National Weather Service!

Amateur Radio Repeaters

NWS offices around the country utilize various spotter networks for severe and other inclement weather verification and reporting.  The various spotter networks are comprised of emergency management officials, law enforcement, fire fighters, EMS personnel, and road crews.  We also utilize the general public with training taking place during the late winter and early spring as NWS personnel travel to various counties to provide training.  A final group of spotters utilized by our NWS office are amateur radio operators.

Amateur Radio Operators (HAMS) are a vital link in the spotter and communication network used by the NWS during severe or otherwise inclement weather.  Not only do they report what they see with their own eyes, but they can report what others see, and also provide communications to other NWS offices should normal communication modes fail.   The following graphics depict single repeaters, linked repeater systems, or a combination thereof which we utilize often.  New repeaters continue to be installed by dedicated and hard-working hams to expand their  networks.  We also continue to learn of and put into use these new systems as soon as possible.

For now, we will not list 2 meter and 70 cm repeaters outside of our 51 county warning area (depicted by the purple outline), unless they also serve some of our counties.  If you notice errors or omissions, know of new repeaters that need to be added, need to change your spotter address or phone number, or just have a SKYWARN/spotting question, drop us a line at dmx.spotteradmin@noaa.gov  and we take care of your request ASAP.  Note:  This email address is not for sending severe weather reports, but instead is for administrative tasks.  For severe weather reporting via the internet, please click here.

Keep in mind the maps depict approximate signal coverage with radio propagation characteristics, geography, equipment reliability, etc. all affecting coverage of a given repeater. Since many of these repeaters are linked please give them a second or two to connect.

Here's a three page pdf file of the same information in a format that will print nicely on three pages.
