Doing an anniversary or a recap? Switch any replay to a clean presentation view: the view tabs, Layers and Share drop away, leaving the map, the clock, the chapters, the playback bar, the map credit and the safety line. Cue it to the minute you want before you're on air. Every chapter comes with a headline and the facts behind it, so you have your beats.

Emergency preparedness

Walk back through a real storm, in order.

Use a real storm for an after-action review or a tabletop exercise. See when the warnings went out, when the reports and outages followed and what the airports did. Pause on any minute and ask what was known then and what came next. Send your team a link to the exact moment you want to discuss.
