The storm is forecast to impact Florida today, possibly as a Category 4 storm. If it makes landfall, it would be the most powerful storm since Hurricane Wilma in 2005 to do so, and could cause as much as $15 billion in economic disruption.
This morning, the National Hurricane Center warned of "life-threatening inundation during the next 36 hours along the Florida east coast and Georgia coast."
Matthew has caused at least 26 deaths across the Caribbean.
