Tropical Storm Debby Set to Cause Major Flooding
Tropical Storm Debby is expected to bring heavy rainfall and persistent rain bands, leading to potential historic flooding in the southeastern United States. After a lull in Atlantic tropical activity in July, the tropics have become active again in August with the reduction of African dust in the atmosphere.
Formed over the weekend, Tropical Storm Debby is forecasted by the National Hurricane Center to possibly reach Category 1 hurricane status before making landfall on the western coast of Florida on Monday. Although not the most severe storm in recent years, Debby will primarily affect less populated areas, including preserves and wildlife regions, making its wind and surge impact more manageable.
Flooding Risks with Tropical Storm Debby
The major threat from Debby lies in the potential for significant flooding across Florida, Georgia, and South Carolina. Moving north-northwest at 13 mph, Debby is expected to follow a typical hurricane path before being blocked by high pressure over the central Atlantic, potentially stalling near the Georgia and Carolina coasts.
Debby’s path after Florida remains uncertain, with possibilities including crossing Georgia and possibly reemerging over the Atlantic Ocean. If it stays near the coast, warm sea temperatures (83-85°F) could sustain the storm, leading to prolonged tropical rainfall and “training” rain bands.
The Weather Prediction Center forecasts 20 to 25 inches of rain from Savannah, Georgia, to Hilton Head Island and Charleston, South Carolina, with higher amounts possible inland.
Increased Tropical Activity from Africa
Florida and North Carolina could also see heavy rainfall due to Debby’s unpredictable path. Additionally, increased tropical wave activity from Africa is expected to intensify in August, signaling a busy period for Atlantic tropical activity. This aligns with forecasts for an active hurricane season, driven by unusually warm Atlantic waters due to climate change and the impending La Niña in the Pacific, which creates favorable conditions for hurricane development in the Atlantic.
