MYRTLE BEACH, S.C. (WBTW) — A tropical storm warning has been issued for the Grand Strand as Ian makes its way toward the coast of the Carolinas.
The National Hurricane Center issued the warning in its 11 a.m. update on Wednesday.
As Ian moved across the Florida peninsula it quickly weaken into a tropical storm.
Ian is forecast to move back out over the open water of the western Atlantic today as a tropical storm. Ian will then quickly make a turn to the NNW, moving back over land Friday afternoon near the border of Georgia and South Carolina likely as a strong tropical storm. Luckily, it shouldn’t be out over open waters long enough to strengthen much more.
Ian will push inland Friday and through the weekend, weakening to a tropical depression by early Saturday morning and then becoming a remnant low by Sunday afternoon.
As of right now, Ian is on pace to impact the Carolinas as a remnant low or weakening tropical depression. For us, this will mean a lower chance of damaging winds but still a great deal of rainfall.
A moderate risk means there is a 40% chance that enough rain will fall to exceed flash flood guidance (FFG). On Friday, FFG is estimated between 5-7″ throughout the area. The Weather Prediction Center has our entire area at a “slight” risk for excessive rainfall and parts of Horry, Florence, and Marion counties at a “moderate” risk.
Expect higher rain amounts along the coast as tropical moisture streams onshore. The bulk of the rain will fall from Thursday night through Friday morning.
It will be windy as well, 30-40 mph will be likely and isolated gusts over 50 mph are possible. There is also a small tornado risk (2%), especially closer to the coast.
Strom surge risk for the Grand Strand is low due to the timing of Ian making landfall in the Low Country. Ian is forecasted to make landfall south of Charleston in the early to mid afternoon, between high tides. Low tide at Springmaid Pier is around 5:40pm.
