Hurricane, Storm Surge Warnings Up for Carolinas; Florence May Stall Near Coast

Hurricane and storm surge warnings were issued Tuesday afternoon ahead of Hurricane Florence, which is increasingly likely to deliver one of the most destructive and prolonged disasters ever seen in the Carolinas. As of 8 pm EDT Tuesday, a hurricane warning was in effect from South Santee River, South Carolina, to Duck, North Carolina, including the Albemarle and Pamlico Sounds. A storm surge warning covered the same area, as well as the low-lying Neuse and Pamlico Rivers just inland. Hurricane and storm surge watches extended southward to Edisto Beach, SC, and north to the Virginia-NC border. A tropical storm watch covers the southeast Virginia coast up to Cape Charles Light and Chesapeake Bay south of New Point Comfort.

Florence was again on the upswing in intensity late Tuesday after its strength was briefly dented Monday night by an eyewall replacement cycle, as explained by Dr. Jeff Masters in our previous post. A new, larger eye (about 30 miles across) is now in place, and that will allow the hurricane’s wind field to expand as well. Satellite images on Tuesday night showed that Florence was still adjusting to its new eye, and had an asymmetric shape with a relatively thin area of heavy thunderstorms on the southwest side. Florence’s top sustained winds were raised to 140 mph by the National Hurricane Center at 5 pm Tuesday. Sustained hurricane-force winds now extend up to 60 miles out from Florence’s center, and tropical-storm-force winds extend out 175 miles. These numbers may grow even larger as Florence matures and expands. At its current size, Florence rates as an average-sized hurricane.

No hurricane-hunter flights gathered data from Florence on Tuesday afternoon, but an Air Force plane penetrated the eye at 9 pm EDT Tuesday, and found a central pressure near 944 mb, just 1 mb below what NHC was estimating in their 8 pm EDT advisory. The mission will last into the early morning hours Wednesday.
