Very good app. I drive a semi & this is very helpful when sky looks threatening . As for the alerts , I have them set and they WORK. Recently on I-59 in southern Miss. when alert went off for severe thunder storm. A few min. later it was raining so hard even up in a semi it was hard to see. Be glad to get rid of adds though.
