Maximum stages and discharges prior to and during July 13-17, 1993, in central Mississippi ABSTRACT January 20-23, 1993, in Southern Mississippi During a 2-day period from the morning of January 19 through the morning of January 21, 1993, a storm system swept through southern Mississippi producing rainfall totals in excess of 8 inches (fig. 60). The town of White Sand received 10.8 inches of rainfall in a 24-hour period (National Oceanic and Atmospheric Administration, 1993). The 50-year, 24-hour rainfall at White Sand is about 10.5 inches (Hershfield, 1961). Maximum stages and discharges were documented at 25 flood-determination sites (fig. 60) that experienced a flood with a 2-year recurrence interval or greater. These floods are summarized in table 37. The most severe flooding occurred on West Hobolochitto Creek (site 24) where the flood was the largest on record and was estimated to have a 200-year recurrence interval. July 13-17, 1993, in Central Mississippi Excessive rainfall from scattered thunderstorms during July 1993 produced flooding in central Mississippi. The city of Vicksburg in west-central Mississippi was the hardest hit, as it received 6.6 inches of rainfall in a 3-hour period beginning at 1900 on July 11 (National Oceanic and Atmospheric Administration, 1993). The 100-year, 3-hour rainfall for Vicksburg is 5.4 inches, according to Hershfield (1961). Maximum stages and discharges were documented at eight flood-determination sites (fig. 76) that experienced at least a 2-year recurrence interval and are summarized in table 50. At Red Cane Creek tributary near Pisgah (site 6), the maximum peak discharge was the largest for the period of record. The flood was more severe at the flood-determination sites with the smaller drainage areas (sites 3 and 6), which indicates the intense but isolated nature of the thunderstorms.
