National Weather Service United States Department of Commerce

March 9-15, 2025 is Severe Weather Preparedness Week in Indiana.

Governor Mike Braun has proclaimed March 9-15, 2025 to be Severe Weather Preparedness Week in the state of Indiana.

The National Weather Service, in conjunction with the Indiana State Police, the Indiana Department of Homeland Security, the Indiana Department of Education, the Indiana Broadcasters Association, the American Red Cross, and Amateur Radio Operators will conduct a statewide test of communication systems on Tuesday, March 11 at 10:15 AM EDT/9:15 AM CDT.

Important Notes - while the drill will be sent using live TOR EAS coding (Tornado Warning), it is only a test, and will be postponed to Wednesday, March 12 if weather conditions warrant.  The test warning will activate the Emergency Alert System (EAS) and include SAME activation on NOAA Weather Radio, but will NOT trigger a Wireless Emergency Alert (WEA).  (NWS Wilmington, OH will send the test for their Indiana counties using the RWT coding, per an agreement with their Cincinnati broadcast market partners)


Help the NWS and partners protect your community: become a trained storm spotter!

As part of NWS efforts to build a Weather Ready Nation, the goal of Severe Weather Preparedness Week is to better educate people about the hazards of severe thunderstorms and tornadoes, and to help everyone be prepared when severe weather occurs.

Each day will focus on a different topic.  NWS Indianapolis will make approximately 5-6 posts via social media throughout each day of Severe Weather Preparedness Week. Visit us on Facebook and X (@NWSIndianapolis) for information on the following themes:

  • Sunday: Weather Ready Nation
  • Monday: Severe Weather Outlooks and Watches
  • Tuesday: Severe Weather Warnings and Tornadoes (Statewide Tornado Drill Day)
  • Wednesday: Other Types of Severe Weather Hazards
  • Thursday: Flooding
  • Friday: Response and Recovery
  • Saturday: Recap of Severe Weather Preparedness Week

Flood Threats Often Overlooked


This week, we also remind Hoosiers to be aware of the underappreciated but deadly dangers of flooding.  On average, flooding is the deadliest thunderstorm-related hazard.  Indiana suffered no known flood fatalities in 2024 - for the first time since 2017.  However, 181 lives were taken by flooding last year across the country.  Preliminary flood fatality statistics for the nation can be found here.  The majority of flood deaths are completely preventable and occur as a result of people driving into flood waters.  Click the "Turn Around, Don't Drown!" barriers below to learn more.  Click the flood safety image to see a Turn Around, Don't Drown PSA on YouTube.

Our partners at the American Red Cross have released an "emergency app" for smartphone and tablet users.  It provides location-based severe weather alerts from the National Weather Service, as well as the ability to quickly send an "I'm Safe" message to the Red Cross in case loved ones are unable to contact you.  Additionally, the application provides access to lifesaving tips on actions to take, shelter locations, and more.  Click here to see it and other Red Cross safety applications designed to help you prepare for and respond to life-threatening weather emergencies and other hazards.

Our partners at the Federal Emergency Management Agency have also produced an app that is your personalized disaster resource for all stages of disaster response - plan, protect, and recover.  Find this app and more information here.

As part of NWS efforts to build a Weather Ready Nation with our partners and the public, severe weather preparedness efforts have also gone national in recent years.  Click the image below to learn more about what YOU can do to "Be a Force of Nature."
