John Keefe of WNYC said anticipate question before your audiences asks them. Is a hurricane headed my way? Am I in a flood zone?

Preparing for an emergency should happen before the storm sirens start blaring. The same goes for your data visualizations, Keefe said. His newsrooms uses Google Fusion tables, Mapbox and Google Spreadsheets to answer listener’s questions in crisis situations.

“Learn and play with (the software) now, because that will help you when things go crazy,” Keefe said. Do it daily, weekly, monthly.Build yourself a library of templates.

Here’s a list to start mapping emergencies before they hit:
Hurricanes, floods, snow, transit strikes, terror attacks, evacuations, toxic spills and releases, fires, shortages of gas, cash and water, zombies (just kidding, but why not?).
