On Monday, astronomical high tides combined with large breaking waves, generated by a distant and offshore Hurricane Florence, caused beach erosion and isolated structural damage to oceanfront properties along the central and southern coast. Low pressure began influencing the state early Wednesday morning with soaking rains of between one and three inches that continued for almost 24-hours. Low clouds and fog were observed Thursday morning before breaks in the clouds allowed for drying sunshine. High pressure followed the wet weather with mostly sunny skies and slowly warming afternoon temperatures through the weekend. For the period, the state average temperature was four degrees below normal.
The highest official temperature reported was 88 degrees at Edisto Beach and Givhans on September 16 and at Givhans, Pritchardville and Johnston on September 17. The lowest official temperature reported was 53 degrees at Cheraw on the morning of September 12. The heaviest official 24-hour rainfall reported was 3.42 inches at Cades ending at 7:00 AM on September 14. The average statewide rainfall for the period was 1.6 inches.
