System type: Tropical storm

System name: Chantal

According to the National Hurricane Center’s 1 pm Saturday advisory, the system strengthened enough to get a name: Tropical Storm Chantal. It found new strength and has evolved from a tropical depression into a tropical storm with sustained winds of 45 mph. The name gain was first included in the 7 a.m. update. Tropical Storm Chantal is currently in the Atlantic Ocean, 105 miles southeast of Charleston South Carolina and 185 miles south-southwest of Wilmington North Carolina. With maximum sustained winds of 45 mph, it is moving to the north at 3 mph.

“… the center of Chantal is expected to move across the coast of South Carolina overnight or early Sunday morning”, analysts explained. They also said “Some additional strengthening is expected before Chantal reaches the coast.”

Today, a system that was previously forecasted as a tropical depression has been officially named Tropical Storm Chantal as it has progressed into a fully formed tropical storm. The system’s new name was first made public in the 7 a.m. advisory.
