Snap Maps went from creepy Big Brother to helpful tool during Hurricane Harvey in August, when people in Texas used the feature to document the storm’s destruction in real time. Now, thanks to Hurricane Irma, it’s Florida’s turn.
Currently, Floridians are using the feature to document their storm preparations —stocking up on groceries, covering windows, leaving town — for Irma, which could make landfall tomorrow.
For now, people are posting lots of pictures from the beaches as Irma’s winds begin to pick up:
Snapchat isn’t the only tech company that’s proving useful during the storm. Google, in conjunction with the Florida government, is posting road closures in real time on Google Maps as a service to those trying to evacuate. Already, 5.6 million people — over a quarter of the state’s population — have been told to leave.
Snap Maps are a relatively new location-sharing feature that let you view videos from your friends and strangers whose posts are public.
To view Snap Maps, open Snapchat and pinch your fingers together on the camera tool. You can then scroll to Florida to see what’s happening.
