Hurricane Debby

MIS RESPONSE TO THE SECOND NAMED HURRICANE OF THE 2024 ATLANTIC HURRICANE SEASON

AN EXCEPTIONALLY ACTIVE EARLY SEASON

Hurricane Debby began forming in the Atlantic Ocean in early-August 2024 as a Tropical Wave, causing showers and thunderstorms as it strengthened to Tropical Depression status whilst moving towards the US.

Debby then made landfall on 05 August near Steinhatchee in Florida's Big Bend region as a Category 1 hurricane, with winds of 80mph.

This was just a few miles southeast of where the Category 3 Hurricane Idalia made landfall on 30 August 2023.

As the second named hurricane of the 2024 Atlantic hurricane season, Debby formed three weeks earlier than the average second named hurricane, which is typically on 26 August. 

Hurricane Debby weakened to Tropical Storm status as it crossed the border into Georgia late on 05 August.

Since making initial landfall, Debby has seen more than a foot of rain fall over parts of Florida, Georgia and South Carolina, tragically leading to the death of at least five people.

After drifting off the coast of Georgia on 06 August, Debby then made second landfall on 08 August 2024 near Bulls Bay, South Carolina, with maximum sustained wind speeds of 50mph.

Debby is on track to move into North Carolina by the evening of 08 August and into northern Virginia by 09 August. 

It is then forecasted to accelerate into Pennsylvania and New York and through New England on 10 August, bringing heavy rains and potentially further flash flooding.

However, it is likely to be downgraded to a Tropical Depression as it moves up the eastern seaboard of the United States.

Debby had dissipated by 12 August, though its remnants were still effecting the northeast US and Canada with rainfall and power outages.
