Authorities posted an interactive map of evacuation routes showing lane reversals on numerous other state and local roads ahead of the total shutdown of coastal South Carolina on Wednesday. Matthew isn’t expected to arrive until the weekend but greater impacts will be along the coast of Florida, coastal Georgia, South Carolina and North Carolina. “Right now, the storm itself is the size of Arizona,” Jim Butterworth, director of the Georgia Emergency Management Agency, told to the media. Hurricane warnings were in effect for Palm Beach and Broward counties and Lake Okeechobee in Florida. Broward County and Miami were added Tuesday to the hurricane watch area. “And things can become much worse than what’s projected at this time,” Gov. Rick Scott warned. Port Canaveral, one of the busiest cargo and naval ports in the world, ordered a total evacuation late Tuesday afternoon for all marinas, port businesses and tenants. In North Carolina, the University of North Carolina at Wilmington issued a mandatory campus evacuation for all students by noon Thursday.
