SAVANNAH, Ga. (WSAV) — We are tracking two difference systems in the Atlantic Ocean. One is strengthening while the other is weakening…quickly. Hurricane Sam is expected to become a major hurricane by the end of the weekend.

Hurricane Sam

Tropical Storm Sam became a hurricane early Friday morning and is now a major hurricane. It is now a category 3 hurricane with 120 mph winds as of the 11 am advisory from the National Hurricane Center. The center was about 1095 miles east-southeast of the Northern Leeward Islands, moving west-northwest at 10 mph.

Sam is currently in a very favorable environment for rapid intensification. It could be a major storm as soon as this evening and become a category 4 hurricane by Sunday.

Through the middle of next week, Sam will still be east of the Leeward Islands and will pose no direct threat to land. There is too much uncertainty beyond that to determine whether Sam will remain over the water or eventually threaten a landfall.

Subtropical Depression Teresa

Teresa continues to weaken today and is now a subtropical depression. Teresa formed almost 150 north of Bermuda Friday evening. The system remains very weak and is not expected to last through the weekend.

As of 11 am Saturday, Teresa has max sustained winds of 35 mph and is stationary. Increasing wind shear will continue to weaken the storm.

Stay with Storm Team 3 for the latest as we continue to track Sam this weekend and all of next week.
