Thursday September 13 2018
Hurricane Florence has weakened to a Category 2 overnight. Winds are now 110 mph and still very powerful. The lower category does not lower the threat to the east coast as there is still wave memory pushing water onshore and plenty of rain to dump as it slows to a crawl for the Carolinas. The outer clouds have reached Maryland as seen in the satellite loops below. Locally we will get showers, but not the main event. Our biggest impact will be on Friday with some areas seeing another round of showers Saturday afternoon. Overall a glancing blow and minor. See more details of the local impact below.
