Teresa strengthens into subtropical storm, causing rip current threats for NC

Teresa has officially formed into a subtropical storm, according to the 5 p.m. advisory.

Teresa's about 700 miles east of Cape Hatteras in NC with maximum sustained winds of 45 mph. While Teresa doesn't seem to be a direct threat to the US, the storm is causing high rip current threats along the NC coast.

Hurricane Sam is continuing to grow. Sam is a category 1 hurricane moving west at 15 mph with maximum sustained winds at 85 mph.

"Sam will continue to intensify," explained WRAL meteorologist Zach Maloch.

Models show Sam strengthening into a category 3 or 4 by the weekend.

Many models show a turn to the north by later next week, but some models keep Sam a little farther south, which means it has a better chance of passing between the Carolinas and Bermuda.

"Most models keep it just east of the U.S., but there could be some coastal impacts for next weekend," Maloch said. "Timing could change. Simply we are in the watching stage."

​Meteorologists are also watching three other areas of interest that have low to medium chances of development and shouldn't impact land.
