RALEIGH, N.C. (WNCN) — The system forecasters have been tracking this week, 94 L, is now Potential Tropical Cyclone Nine and will likely impact the Carolinas next week. This system will become Imelda over the weekend as it slowly moves north through the Bahamas. The National Hurricane Center uses this naming system to warn areas of tropical storm conditions before a storm forms into a tropical system.
The system has been moving west-northwestward at about 10 mph during the past 12 to 24 hours. However, this motion is expected to change as the disturbance is forecast to turn northward in southerly flow between a large-scale trough over the eastern U.S. and a subtropical
ridge over the central-western Atlantic.
This track should take the system across the central and northwestern Bahamas over the weekend. The models are in good agreement through that time period, but they diverge significantly early next week when the synoptic pattern becomes complicated.
The track is a complicating factor in the forecast. The National Hurricane Center (NHC) shows just 40 miles between forecast positions. That’s a forward movement of 1.6 mph. With a slow-moving system, expect either near shore or just onshore. Rain is the main concern for the Raleigh area, as the storm moves to our south.
With the track uncertainty beyond Monday, make sure to keep up with the forecast this weekend and early next week as this continues to evolve.
