In anticipation of Hurricane Irma, Florida governor Rick Scott has announced that the state is working with Google’s emergency response team to mark closed roads on Google Maps in real time. This will help with evacuation plans.

Irma is currently a Category 5 hurricane barreling through the Caribbean, and it's expected to impact Florida over the weekend and early next week. Yesterday, officials ordered mandatory evacuations in major parts of Florida, including Miami-Dade County and Fort Lauderdale.
