South Carolina’s governor on September 6 declared a state of emergency for South Carolina, saying the hurricane now “may pose a significant threat to the state.”

“The National Hurricane Center has determined from forecast models that the State of South Carolina may be impacted by Hurricane Irma,” the governor wrote. “I have been advised that Hurricane Irma, and the associated wind, heavy rain, flash flooding, and severe weather, to include tornadoes, may pose a significant threat to the State of South Carolina.”

The governor also ordered that “the South Carolina Emergency Operations Plan be placed into effect.” He ordered the activation of South Carolina National Guard at the the discretion of officials. Read the governor’s full September 6 statement here:

The storm is unpredictable, though, and no one knows its path for certain.

Georgia’s governor has also declared a state of emergency in the following counties along the coast: Bryan, Camden, Chatham (where Savannah lies), Glynn, Liberty and McIntosh.

Here’s the evening forecast cone from the National Weather Service, showing how the path has expanded to Georgia and South Carolina, while still threatening Florida:

The latest update from the Charleston weather office reported on September 6: “Impacts associated with Hurricane Irma are expected this weekend into early next week. It is still too early to pin down the magnitude of the impacts as there remains uncertainty with the track the hurricane will take and how strong it will be as it approaches the Southeast United States. Everyone across Southeast South Carolina and Southeast Georgia, especially those in hurricane prone areas, should have a hurricane plan in place and continue to monitor the latest forecasts from the National Hurricane Center. Rip Currents: Long period swells generated by approaching Hurricane Irma will persist into early next week. These swells will enhance the risk for powerful and dangerous rip currents at area beaches into early next week as Irma draws closer to the region.”

There was no mandatory evacuation for South Carolina on September 6.

Spaghetti models can provide further insight on the storm; the latest are generally showing it’s shifted to the east (which could be better news for Florida), while then charting a course toward Georgia and South Carolina.
