On top of intrusive ads that can prevent you viewing a tornado warning, this app failed to inform me of a tornado warning today. Here in Iowa, I went under a tornado warning that would expire at 5:15 PM. This app would fail to update that the tornado warning got extended to 5:45 PM, and this app showed me as being all clear with no active warnings. It was wrong, and it never displayed the new, current warning even when refreshing the app. 0 stars, as this kind of issue could ultimately kill you
