If you are playing outdoor sports, swimming in a pool or at the beach, you can get notified of nearby lightning strikes using the My Lightning App. The app gives you the warnings you need to plan ahead and be safe.
The app shows you where the most recent lightning strikes have happened. Zoom in for more detail. Red dots show the most recent strikes, yellow dots are strikes from 15-30 minutes ago and Gray dots are older.
Set the mile radius to get automatic notifications when lightning starts to strike within that distance of your last known location. You can monitor the storm in real time.
This gives you advance notice to clear the field or get out of the water and find shelter.
My Lightning Tracker is free.
