(CHARLESTON, S.C.) -- Tropical Storm Bonnie was swirling off the coast of South Carolina Saturday night, disturbing Sunday plans for beachgoers.
According to the National Hurricane Center, 40 mile-per-hour winds and heavy rains from the second named storm of the season were hitting South Carolina and southern North Carolina's coast Saturday night.
The official start of hurricane season does not begin for another four days, but Michael Brennan, a senior hurricane specialist for NHC, said the tropical storm was not expected to intensify.
"The storm's right now moving over the Gulf Stream and that's what's sort of giving it a boost of energy today but it's about to move out of those warmer waters and into the cooler waters that are right off shore off the southeast coast so we're not expecting too much more intensification," he told ABC News on Saturday night.
Bonnie will move ashore and likely make a landfall somewhere between Savannah, Georgia, and Charleston, South Carolina, on Sunday morning. Wind gusts up to 40 mph are possible along the coast with 1 to 3 inches of rainfall. Locally higher amounts of rain could fall and produce some flash flooding.
A concern for beachgoers throughout the holiday weekend will be dangerous rip currents all along the Southeastern coast of the U.S.
"There's at least some risk of rip currents all the way from portions of central and north Florida up through the Carolinas," Brennan told ABC News.
