Hurricane Ian Advisory #5
September 29, 2022 – 3:00 pm

Tropical Storm Ian has emerged from the east coast of Florida and has entered the Atlantic Ocean. Ian currently has maximum sustained winds of 70 miles per hour. Additional strengthening is possible over the next 24 hours. The current forecast calls for Ian to regain hurricane status prior to making a second landfall on the South Carolina coast on Friday.

As of 11:00 am on Thursday, the National Weather Service has issued a HURRICANE WARNING for the entire South Carolina coast. This means that hurricane conditions (sustained winds of 74 mph or higher) are expected within the specified area. A STORM SURGE WARNING remains in effect for the entire coast.

According to NWS Charleston, there is high confidence that Hurricane Ian will impact our area. Below is a summary of today’s report from NWS Charleston:

  • Minor wind damage is possible today and tonight. Minor to moderate wind damage will be possible on Friday and into Friday evening. The strongest tropical storm force winds (39-73 mph), and possibly low-end hurricane force wind gusts (74+ mph), are expected along the immediate coast and within any rain bands on Friday and into Friday evening.
  • Life threatening storm surge inundation is expected, especially on Friday. Major coastal flooding is expected today and tonight through Friday, especially during times of high tide. A storm surge of 4-7 feet is possible in Charleston County.
