July 5 (UPI) — Tropical Storm Chantal formed in the Atlantic on Saturday morning and is projected to reach South Carolina and North Carolina on Sunday, the National Hurricane Center said.
Chantal, the third named storm of the season, will be the first system to impact the United States this Atlantic hurricane season, which began June 1.
“As tropical cyclones go, this storm will be relatively minor and short-lived,” Frank Strait, severe weather liaison with the South Carolina State Climate Office, told the Island Packet.
In the 2 p.m. EDT update, Chantal had maximum sustained winds of 45 mph and was traveling northward at 3 mph. In the 11 a.m. update, the winds were 40 mph.
The storm became a tropical depression Friday night off the coasts of Northeast Florida and Georgia.

Chantal was about 105 miles south-southeast of Charleston, S.C., and about 185 miles south-southwest of Wilmington, N.C.
A tropical storm warning is in effect for the South Santee River, S.C., to Surf City, N.C. A tropical storm watch goes from Edisto Beach to South Santee River.
Tropical-storm-force winds extend outward up to 105 miles east of the center.
“Chantal has barely moved since last night, but a motion to the north-northwest is expected to begin soon,” NHC forecasters said. “The main steering features appear to be a mid- to upper-level low over the Gulf and a narrow mid-level ridge across the mid-Atlantic region.”
Some strengthening is expected before Chantal reaches the coast, NHC said.
A turn to the northeast is forecast by Sunday night, NHC said. On the forecast track, the center of Chantal is expected to move across South Carolina’s coast Sunday morning.
Chantal is expected to produce heavy rainfall in the Carolinas through Monday with 2 to 4 inches and local amounts of 6 inches. NHC said these rains could cause flash flooding
“The combination of storm surge and tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline,” NHC said.
Storm surge is forecast at 1-3 feet from South Santee River to Surf City and 1-2 feet from Edisto Beach to South Santee River.
Also, isolated tornadoes are possible Saturday night into Sunday along South Carolina’s eastern coast and much of North Carolina, NHC said.
“This was a classic example of homegrown development, by which a tropical storm formed close to the southeast Atlantic coast and in an area where it is typical for July,” AccuWeather Lead Hurricane Expert Alex DaSilva said.
Andrea and Barry, the first two named systems of the Atlantic hurricane season, have dissipated.
