What’s the must-have weather app, according to longtime meteorologist Paul Douglas?

It’s one his company provides called Aeris Pulse Weather, available to download on both i0S and Android for a one-time cost of 99 cents. The app personalizes local weather threats for the user.

“It gives you alerts, notifications based on your GPS location,” he says. “It tells you where the hail is, the lightning, the heavy snow in relation to where you are, so you get these updates on the big weather days.” For an added cost, optional in-app subscriptions allow access to forecast models, lightning strike data and weather-related traffic hazards.
