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.
