October Climate Summary: Drier than Normal for SE GA & NE FL

October 2013 ended up drier than normal after another month of below normal tropical cyclone activity in the Atlantic Basin. The main rainfall event for the month was the remnants of Tropical Storm Karen that moved out of the Gulf of Mexico and across North Florida on the 7th and 8th of the month. Warmer than normal temperatures during the first half of the month were tempered by a cooler than normal period at the latter portion of the month to allow for near normal average temperatures for most of the region. Several locations over inland areas of southeast Georgia and the Suwannee River Valley of North Florida fell into the 35 to 40 degree range on the mornings of the 26th and 27th, no daily climate records were set and temperatures remained just warm enough to prevent any frost formation.

The two graphics below tell the precipitation story for the month of October. The first one shows Total Precipitation for the month, where it can be seen that most areas received less than 2 inches of rainfall, except localized 2 to 4 inch amounts along the I-95 corridor of Coastal Southeast Georgia & Coastal Northeast Florida including the St John's River Basin and southwest to Marion County, and an isolated 4 to 6 inch bullseye across inland Flagler County due to Tropical Depression Karen rainfall amounts. Some areas along the I-75 corridor of NE FL that received widespread summer rainfall, barely received measurable rainfall for the month, including Gainesville, FL where only 0.08" fell the entire month, tying it for the 3rd driest October on record! The second graphic shows the October Percent of Normal Precipitation which relays the fact that almost the entire region was WELL below normal except for a small area of Flagler County. This dryness has persisted from September through October and has led to the introduction of D0 conditions (Abnormally Dry) in the latest version of the Drought Monitor posted online. The Climate Prediction Center (CPC) is forecasting the development of more widespread drought conditions into SE GA and NE FL into the early 2014.
