Google has a long history of offering maps-based emergency data, the most recent example being a live replica of the RFS bushfire maps for NSW. The next step in that process: from today, Google will offer NSW live bushfire warnings as you search Google Maps, warning you of potential issues as you plan your travel.
Google will use its Public Alerts service to offer warnings when searches are made in areas in NSW where a bushfire warning is active. Android users may see alerts from Google Now if there is a bushfire where they are located or at a place where they have a scheduled appointment. It's a service you hope you'll never use, but it's a very welcome addition.
Those bushfire alerts haven't yet been added for other states, but the national Google Crisis Map shows all active emergency warnings across the country.
