SPC has upgraded the severe weather risk from "Slight" to "Moderate" over about the southern half of the peninsula. While that may not sound too bad, keep in mind that they only use three risk levels (slight, moderate, high), with "High" risk generally reserved for big tornado outbreak-type days in the Plains. A Moderate Risk is pretty rare for a landfalling hurricane scenario, so the risk of tornadoes is considered to be somewhat greater than normal for a tropical cyclone:
