Much of Indiana has a moderate risk of severe weather tonight, including an elevated risk of strong tornadoes, according to the National Weather Service (NWS) Storm Prediction Center.
Especially disconcerting on Feb. 28 is the forecast that much of the severe weather might arrive after many Hoosiers have gone to sleep.
That makes now a good time for Hoosiers (and everyone else who lives an an area that ever receives severe weather) to make sure they have good ways to know about any warnings their local NWS offices issue.
So here’s my list of the best ways to get tornado, severe thunderstorm and flash flood warnings.
Wireless Emergency Alerts
If you have a modern smartphone, the ability to receive tornado and flash flood warnings via the wireless emergency alert (WEA) system is built in. It should have been enabled when you bought the phone. Unless you have since turned WEA off, it will scream at you if you’re under or near a tornado or flash flood warning.
Severe thunderstorms are often deadly, in part because their straight-line winds can blow trees down on houses, cars, etc. But you won’t get severe thunderstorm warnings via WEA, so you’ll need one of the warning methods below for that.
Several smartphone apps can give you warnings with even more geographical precision than WEA. Plus these apps can warn you about severe thunderstorm warnings, as well as tornadoes and flash floods. My favorites are:
The first two are not free, but they’re inexpensive and effective. The FEMA app is free.
Your local television station might also offer a free app that can provide warnings. Visit your favorite stations’ websites to find out.
The American Red Cross also has a free app, but I do not recommend it. In my experience, its tornado warning alerts have arrived several minutes late.
NOAA Weather Radio
This is a special radio that receives spoken weather information directly from the NWS. Models are available for around $30. You can find them lots of places, including your corner Walgreens pharmacy. You can set these radios up so they remain silent until and unless the NWS issues any kind of warning for your county.
One disadvantage of NOAA Weather Radio is that it only provides county-wide alerts. So, if you live in a large county, you could receive an alert for a storm that won’t affect you. But that’s better than being in the path of a dangerous storm and not knowing! Plus, NOAA Weather Radios might be the best at waking you when severe weather threatens late at night.
I do not consider Twitter to be a primary way to receive weather warnings, but it’s a good supplement, especially if you follow your local NWS office and set your smartphone to give you a push notification every time that office sends a tweet.
The map above shows the coverage area of every NWS office that covers any part of Indiana, as well as the Twitter handle of each office.
Here’s a clickable list, for easy reference. You can use these links to monitor the tweets of each WFO, even if you don’t have a Twitter account:
- Chicago @NWSChicago
- Northern Indiana (North Webster) @NWSIWX
- Indianapolis @NWSIndianapolis
- Wlmington, Ohio @NWSILN
- Paducah, Ky. @NWSPaducah
- Louisville, Ky. @NWSLouisville
If you’re not in Indiana, you can identify the appropriate WFO and social media feeds for any location in the U.S., by ZIP code or city and state name by entering them on the NWS “Social Media” page.
Twitter hash tags can also yield helpful information. Commonly used for posts about the weather in Indiana is #INwx.
Text messages and phone calls
If you don’t have a smartphone, there might be other ways to get alerted of weather warnings, depending on where you live.
Some local governments operate “reverse 911” systems that can text or even place a voice call to you when a warning is issued. To find out if this is available where you live, check the website of your municipal and/or county government and/or emergency management agency, or call the administrative number for your local police department (don’t call 911 for this information!).
Another possibility is that some local TV and radio stations provide weather alerts via text messages. Check the websites of your local stations to see if they do.
What about tornado sirens?
It’s very important to understand that tornado sirens — known in the emergency management community as outdoor warning sirens — are designed to alert only people who are outdoors. You’re not likely to be outdoors late at night. Even if you can sometimes hear tornado sirens inside your house, the sound isn’t likely to be loud enough to wake you (unless you live very close to a siren).
Therefore, you must not rely on tornado sirens to warn you of late-night storms while you’re indoors and possibly asleep. Instead, acquire one of the warning methods described above.
