As Hurricane Irma nears Florida, everyone is in a rush to fill up their tanks. About 40% of the gasoline stations in the Miami-Fort Lauderdale region are now without fuel. Floridians have turned to the Crowd-Sourced ‘Gas Buddy’ App to determine which stations still have gas.

Patrick DeHaan, the senior petroleum analyst at Gas Buddy, said their newest feature – the Gas Availability Tracker – has now been rolled out to those who could be affected by Hurricane Irma in Florida, Georgia and the Carolinas.

“The tool seeks to help motorists in need to find gasoline, and certainly in some cases. will also help motorists find stations that have power,” DeHaan said.

The app was developed during Hurricane Harvey in Texas. People can log in to view gas stations in their area. A red fuel pump icon indicates the station currently has gas. A red lightning bolt icon indicates the station has power, especially helpful for those in areas affected by power outages.

The data is largely crowdsourced by users who submit information through the app.

Florida Gov. Rick Scott announced in Miami that he’s asked the governors of Alabama and Georgia to waive trucking regulations so tankers can get fuel into the city, which is experiencing one of the largest shortages statewide as residents prepare for the hurricane’s landfall.

He told residents of the Florida Keys that “we’re doing everything to get fuel to you as quickly as possible.” Tourists are under a mandatory evacuation order, which began Wednesday morning.

Residents will then be ordered to evacuate, but the fuel shortage is putting a hitch in that.
