Wet weather, circulating around the remnants of once Tropical Storm Hermine, started the week with heavy flooding rains in Charleston. On Monday over 10 inches was reported at Charleston Airport and over eight inches in the city. Flash flooding caused evacuations, property damage and road closings. Wildfire threats across high elevation sites were temporarily reduced when an estimated one-half inch of rain fell. High pressure replaced the cloudy, rainy conditions with dry, sunny days and cool mornings. This long awaited change of seasonal weather continued through the week with a slow warming trend. By late in the day Sunday, high clouds associated with Hurricane Georges, located near the Mississippi coast, could be seen on the southwest horizon. Temperatures for the period averaged three degrees above normal.
