NWS Memphis SKYWARN

What is SKYWARN®?

Severe weather  is a consistent and dangerous annual threat across the United States. These events cause hundreds of injuries and deaths and result in billions of dollars in property and crop damages every year. To help mitigate this danger and obtain critical, on-the-ground weather information, the National Weather Service (NWS) established SKYWARN® in partnership with local organizations.

SKYWARN® is a vital volunteer initiative comprising between 350,000 and 400,000 trained severe weather spotters. These dedicated volunteers act as the nation's first line of defense against dangerous storms. They serve their communities by observing weather conditions and providing the NWS with timely, accurate reports of severe weather. While they report on all weather hazards, their main focus is documenting severe local thunderstorms—essential information given that the U.S. averages over 10,000 severe thunderstorms, 5,000 floods, and more than 1,000 tornadoes annually.

Since the program's start in the 1970s, the information gathered by SKYWARN® spotters has been indispensable in protecting the public. This ground-truth data, when combined with advanced technology like Doppler radar and improved satellite imagery, has enabled the NWS to issue significantly more timely and accurate warnings for tornadoes, severe thunderstorms, and flash floods. Ultimately, the efforts of SKYWARN® volunteers provide their families and neighbors with the most precious gift of all: time—minutes that can save lives.

How to become a SKYWARN® Storm Spotter?

Many people ask how they can become a member of SKYWARN. It's important to know that SKYWARN isn't a club you "join," but rather a concept - a network of citizen volunteers who help their community and the National Weather Service (NWS) by observing and reporting hazardous weather in their area. Essentially, anyone can be a storm spotter and submit reports directly to the NWS.

If you want to be part of an official local SKYWARN storm spotter network, you should contact your city or county emergency management office for specific information. Many communities organize their own networks, often comprised of amateur radio operators, fire and police personnel, or other volunteers. These local groups may have specific training and membership requirements, so local officials are the best resource to find out how you can get involved.

What is covered in a SKYWARN® Storm Spotter Class?

• Severe thunderstorm characteristics and associated threats.

• Cloud formations relevant to severe weather.

• How to report your observations effectively.

• Basic weather safety practices.

We strongly recommend everyone attend a SKYWARN® course at least once every two years to refresh these critical concepts. Training certificates are provided at each class if needed. 

Important Note: NWS Memphis does not issue Spotter IDs or Spotter Numbers.
