RALEIGH, N.C. (WNCN) — The system forecasters have been tracking this week, 94 L, is now Potential Tropical Cyclone 9. This will become Imelda over the next 48 hours. The National Hurricane Center uses this 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 earl
