RALEIGH, N.C. (WNCN) — Tropical Storm Ian has sustained winds of 50 mph Sunday morning, and is moving west-northwest at 14 mph. A gradual turn to the northwest, and then north is expected today. Ian is also becoming more organized, and rapid intensification is possible.

Ian is expected to strengthen into a hurricane with maximum sustained winds of 80mph within the next 24 hours. Forecasters at the National Hurricane Center predict Ian will become a strong category 4 hurricane with sustained winds of 130 mph in the southern Gulf of Mexico early Wednesday.

The eventual track of Ian beyond Wednesday, however, remains a bit uncertain. Global forecast models have been shifting west over the last 24 hours, but still contain a large degree of uncertainty.

Friday’s forecast track was quite literally all over the place as weather models were struggling with the exact placement of Ian’s center, and the overall steering pattern in the upper layers of the atmosphere to the north. Over the last 72 hours, however, model guidance has gotten into somewhat better agreement. It can be noted the spread is much lower, especially within the first 2-3 days of Ian’s path as it reaches Cuba. However, uncertainty remains about where Ian will eventually make landfall across the southeast. Stay tuned for additional updates.

Elsewhere, the tropics remain active with Tropical Storm Gaston still hanging on in the north Atlantic. Tropical Storm Hermine has dissipated off the coast of Africa, but there is another disturbance in the Atlantic which has a 20% chance of development. Other than Ian, none of these systems will have an impact on the United States.
