If that latest update verified, it would definitely be a nightmare - i.e., coastal southeast Florida appears to be in the relative center of the cone's extrapolated "central line". There are strips of barrier islands all up and down the coast and with it being low-lying and swampy anyway, any storm surge would probably travel quite a bit inland. Just seeing the real-time storm surge video from Michael's landfall in the pan handle last year, was jaw-dropping.
