June 2012 Climate Summary - New Rainfall Records Set

June 2012 Climate Summary - New Rainfall Records Set at Jacksonville & Gainesville

Tropical Storm Debby served as the focal point to help set multiple daily and monthly rainfall records for the month of June at Gainesville and Jacksonville in northeast Florida. Rainfall totals of 15 to 25 inches were seen during the last week of the month from Tropical Storm Debby...mainly along the Florida/Georgia border southward into the I-10 corridor of northeast Florida. This event helped send rivers into major flood status along the St Mary's, Suwannee and Santa Fe Basins and along the smaller Black Creek basin in Clay County. The month of June ended up cooler as well due to the abundant rainfall and associated increased cloudiness. The abundant rainfall over much of the region has ended the short-term drought except for portions of inland southeast Georgia as seen in the latest version of the U.S. Drought Monitor. The forecast for the month of July from the Climate Prediction Center (CPC) is for equal chances (EC) of above, below, or near-normal temperatures and precipitation and can be seen at the following link.
