As Hurricane Irma barrels toward the southeastern US, it can be difficult to stay on top of the storm’s erratic movements and fluctuating intensity. Fortunately, MyRadar, developed by Andy Green, the founder and CEO of the software application development company ACME AtronOmatic, uses NOAA data to display live updates of the location and intensity of the storm, as well as hurricane and storm surge warnings.

The app has a free version and a paid “Hurricane Tracker” upgrade for a one-time fee of $2.99. The free version shows real-time wind and weather patterns that allow you to track the current status of a hurricane, and the paid tracker adds additional details, such as the storm’s past position and strength, its current category and maximum wind speeds, and the “cone of probability”—what path it will likely take over the next couple of days.
