President Barack Obama is warning that Matthew is “still a really dangerous hurricane.”

Meeting in the Oval Office on Friday with FEMA Administrator Craig Fugate, Obama said he was concerned about storm surge and that as the hurricane moves north, areas such as Jacksonville, Florida, and Georgia might be less prepared.

Obama told those living in affected areas that, “If they tell you to evacuate, you need to get out of there and move to higher ground.”

He noted that “because storm surge can move very quickly … people can think that they’re out of the woods and then suddenly get hit, and not be in a positon in which they and their families are safe.”

The president pleaded with people to listen to the warnings of state emergency personnel “because we can always replace property, but we cannot replace lives.”
