Heavy rainfall last week relieves drought conditions in 9 counties
Heavy rainfall last week has alleviated drought conditions in nine counties; Charleston, Berkeley, Georgetown, Williamsburg, Horry, Marlboro, Dillon, Marion, and Florence (see table below). According to Mark Malsick, South Carolina State Climatology Office Severe Weather Liaison, "Last week’s heavy rain was due to several distinct, inter-related weather features. A passing cold front brought the first rain across the state on Sunday and Monday. This front stalled offshore and became a conduit that tapped into tropical Gulf of Mexico moist air. Midweek, as the remnants of Tropical Storm Nicole streamed north, a compact low pressure center formed on the stalled front triggering more thunderstorms and heavy rain for the coast and Pee Dee region."
Hope Mizzell, S.C. State Climatologist, "September was on tap to be one of the driest on record until last week’s rain. For some locations, like Andrews, it went from being the second driest September (0.38") to the fifth wettest (10.18") in 50 years. The very dry conditions preceding the rain helped minimize the flooding impacts. All locations received welcome rain last week, but 37 counties will remain in drought because the rainfall amounts were not sufficient to improve all drought indicators."
