10 a.m. Update on Hurricane Helene

NEW ORLEANS (WGNO) – We are less than 12 hours ahead of landfall, for what could potentially be the most devastating hurricane of the 2024 season.

Hurricane Helene’s last reported sustained winds were of 100 mph at 7 a.m. this morning. Now, wind speeds have jumped up to 105 mph. Helene is still a Cat. 2. Once winds of 111 mph are recorded, Helene will become a Cat. 3.

Saildrones are essentially unmanned ships placed in the gulf to collect data in storms such as Helene.  They measure atmospheric and oceanographic conditions in real time. NOAA has captured one photo already from SD-1083, which already shows 4 meter waves.

Landfall is expected to be between Apalachicola and the big bend region of Florida. This is where the strongest winds and highest surge will be seen. HOWEVER, this storm is massive. Impacts will spread WELL BEYOND the forecast cone. Rainfall has already began in Florida this morning. Flooding is already starting in portions of the Carolinas and Georgia.

Rainfall amounts of 12-16″ are expected in the western part of the Carolinas and Eastern Tennessee through the weekend. Through the southern Appalachian mountains, landslides are a major concern. The terrain is higher than surrounding areas. Excessive rain will runoff downslope taking mud, land, debris, loose brush along with it.

Georgia will experience hurricane force winds even after Helene has made landfall and crossed over Florida. Helene will keep hurricane strength overnight, posing additional wind and flooding threats to Georgia.

Surge in the Big Bend region of Florida will be up to 15-20 ft. Officials are describing this as “unsurvivable”.
