NOAA National Hurricane Center stated at 5:00 AM EDT (August 31, 2023) that the center of Idalia moved offshore of the coast of northeastern South Carolina. Strong southwesterly vertical wind shear has displaced the deep convective bands and heavy rainfall well north and northeast of the center over eastern North Carolina and the adjacent Atlantic.
Idalia has turned east-northeastward between a mid-level anticyclone over the Bahamas and a mid-tropospheric trough moving eastward over the northeastern United States. The anticyclone is forecast to retrograde over Florida during the next couple of days, causing Idalia to turn east-southeastward tonight and Friday.
Little change in strength is predicted today, but strong upper-level winds and drier mid-level air are likely to cause some gradual weakening by the weekend.
Key Updates:
- Areas of flash, urban, and moderate river flooding, with considerable impacts, will continue across coastal North Carolina through today.
- Coastal flooding is expected within the Storm Surge Watch area in North Carolina today. Residents in these areas should follow any advice given by local officials.
- Tropical storm conditions are expected in northeastern South Carolina and portions of eastern North Carolina today.

Real Time Buoy Data for Idalia
Idalia projected path is expected to impact the southeast U.S. coast through early next week. As the storm moves north, explore mooring stations in the Southeast supported by SECOORA. The information collected provides real time updates on the storm’s wind speed and more.
Florida buoys are operated by University of South Florida Coastal Ocean Monitoring Prediction System.
North Carolina and South Carolina buoys are operated by UNCW Coastal Ocean Research and Monitoring Program.
The WebCOOS (Webcamera Coastal Ocean Observing System) allows users to stream live camera feeds in real-time as Idalia approaches the Southeast. The cameras are being used to remotely monitor flooding, document the timing, duration, and extent of dune impacts, and predict rip currents.
