SKYWARN® Program

Skywarn spotters for the National Weather play an important role in our warning process and help our communities stay safe.



SKYWARN Class Schedule


For 2021, ALL classes will be held online in a virtual format. Classes are offered on different days of the week and at different times, but if none of the class times work for you, a recorded version will be available as well. If you sign up for a class and miss it, we'll send you the recording and you can still register as a spotter. 


  1. Click the class you would like to attend below to show the registration link, or simply click here: Basic Class Registration / Advanced Class Registration
  2. Complete the registration form. If more than one person will be watching, you don't need to register more than once - we'll send an email about how to register as a spotter and get your certificate after the class. 
  3. Once registered, you will receive an email with a link to join. Before the class, please visit the GoToWebinar System Check and try a test session to make sure your computer, tablet, or smartphone is ready to attend the class! If you do not have a strong internet connection, you will have the option to call in by phone to listen to the audio. And if you end up having technical problems, you will receive a link to a recording after the class.

2020 Skywarn Spotter Training - Online Recorded Version

Note: A 2021  recorded version is planned but not yet available. We expect it to be posted by late April. If you would like to get trained before then, you are more than welcome to take the 2020 training and follow the instructions below to register! Thank you for your interest.

If you missed the webinars last spring, it's okay! We recorded the presentation and it's available for you to watch anytime. If you're from the Northland and want to register to be a spotter, or you just want to get a bit of refresher training, please check out the recorded version! To register as a spotter (or to refresh your contact information if you're a current spotter), following these three steps: 1) Watch the five-part video series 2) Write down each of the 5 "code words" presented in the videos 3) Fill out the Spotter Registration Form. A few days after filling out the form, we'll follow up with a "hand out" document from the class that has our spotter phone number, a summary of what and how to report to our office, and some links to websites we discussed during the presentation. If you have questions, comments, or feedback on this class or the Skywarn program, please contact Warning Coordination Meteorologist Joe Moore:

Looking for a recording of the Advanced Skywarn training? Once you complete the basic training, please email Joe (above) for a link to the Advanced class recording! Note that we do not have "advanced" spotters or give any special certification for taking the advanced class, it's just an optional supplement to our basic training.

What is SKYWARN?

The National Weather Service's SKYWARN® program provides FREE 2-hour training to volunteers in the community who help identify and report severe weather including large hail, damaging winds and tornadoes.

Since the program began in the 1970s, the information provided by SKYWARN® spotters has helped the National Weather Service issue timely and accurate warnings to protect lives and property. There can be no finer reward than to know that their efforts have given communities the precious gift of time, the seconds and minutes which can help save lives.

Each Spring, National Weather Service offices across the country train volunteers within their area of responsibility. At the Duluth office, we are responsible for training across northeastern Minnesota and northwestern Wisconsin. Our neighboring offices in Grand Forks, Minneapolis, La Crosse, Green Bay, and Marquette offer training for their service areas.

Who can be a spotter?

We encourage anyone with an interest in weather to attend a SKYWARN® class in your community to become an official and trained weather spotter. No registration is required, just show up. Anyone who spends time outdoors, whether working, camping, fishing, golfing, or hiking will also benefit from a SKYWARN® class. Public safety personnel are also encouraged to attend SKYWARN® training.

What does Skywarn Spotter training cover?

SKYWARN® training covers the following topics:

  • The mission of the National Weather Service and how SKYWARN® spotters play an important role in the warning process.
  • Thunderstorm formation and the types of thunderstorms. We'll study the meteorological dynamics involved in thunderstorm production and what it takes for a storm to produce damaging winds, large hail, and tornadoes.
  • Visual indicators spotters can look for to identify possible severe weather. This includes types of clouds associated with specific areas of a thunderstorm, how to identify rotation and discriminate between strong and weak rotation, and discriminating between tornadoes and look-a-likes.

Current SKYWARN® spotters are asked to attend training at least every 4 years in order to refresh their training.


Is there a cost for the training?

No. The National Weather Service provides training free of charge. 


Do you offer an Advanced spotter class? What does the Advanced spotter training cover?

Yes! This class will go more in-depth into thunderstorm development, storm identification, and radar interpretation. Spotters should take the basic/normal course before taking the Advanced course. If you can't make a live version, a recorded version is available upon request - to access the recording, or if you have a topic you'd like to see covered in the Advanced course, please email Joe at

What's my spotter ID? When will I get my spotter ID card?

Going forward, we will no longer be using spotter ID numbers. For future in-person classes, we will still distribute a business card with our contact information and some quick reference information, but we are discontinuing the ID numbers. If you still have a spotter number you can use it when you call our office, but we will no longer assign new spotter ID numbers. 


What other training is available?

In fall 2020, NWS Duluth introduced optional Winter Spotter Training. Click the link to watch a recording and find out more about how you can help us during the winter season!

An alternative online training course is available on the COMET MetEd website (free registration is required). The online training is a great supplement and annual refresher, but we recommend taking our course as well (live or recorded version) to learn about how to best get reports to our office.
