Predicted wind speeds in Atlanta
Hurricane Idalia made landfall as a Category 3 hurricane on Wednesday morning, with sustained wind speeds of up to 130 mph before being downgraded to a Category 2 hurricane with sustained wind speeds of 110 mph. By the time Hurricane Idalia reached Atlanta, it had weakened into a tropical storm. While Atlanta was not expected to experience tropical storm conditions, residents could still expect gusty winds and some rain. Meteorologist Brian Monahan predicted that wind speeds would peak at 35 mph, especially in the southern suburbs.
The hurricane caused significant damage in southern Georgia near Valdosta due to high winds and flooding rains. Storm surges in the area were forecast to reach 12 to 16 feet, with some locations exceeding the values observed in the 1993 Storm of the Century. The storm also caused widespread power outages, with approximately 300,000 homes and businesses in Florida, Georgia, and the Carolinas without electricity as of 5:30 a.m. Thursday.
In preparation for the hurricane, Atlanta's Hartsfield-Jackson International Airport issued travel waivers and advised passengers to check their flight statuses. Many airlines waived change fees for passengers wishing to alter their travel plans due to the storm. Some passengers flying into or out of Atlanta decided to rebook their flights to avoid potential disruptions, while others chose to wait and see if their flights would be impacted.
The wind speeds experienced in Atlanta due to Hurricane Idalia were significantly lower than the initial wind speeds of the hurricane when it made landfall.

Rainfall and flooding in Atlanta
Atlanta, Georgia, has experienced several instances of severe rainfall and flooding in recent years. In 2009, the Atlanta metropolitan area suffered catastrophic flooding due to multiple days of prolonged rainfall. The heavy rains, enhanced by moisture from the Atlantic Ocean and the Gulf of America, exceeded the capacity of local watersheds. This resulted in historic flash flooding, with an estimated 10 to 20 inches of rain falling within 24 hours. The flooding caused substantial damage, leading to an initial property damage estimate of $250 million, which was later raised to $500 million. More than 20,000 homes, businesses, and buildings were severely impacted, and unfortunately, 10 lives were lost.
In April 2025, severe weather, including high winds, heavy rainfall, and the possibility of tornadoes, threatened metro Atlanta once again. A tornado watch was issued for multiple Georgia counties, and residents were warned about potential flash flooding. The storm system was expected to bring significant rainfall, with meteorologists forecasting up to two to four inches of rain in most of North Georgia. The focus was on areas near rivers and creeks that are prone to flooding during severe weather events.
Additionally, in late August 2023, Hurricane Idalia, a Category 4 hurricane, posed a significant threat to the region. While the hurricane made landfall in Florida, it moved across Georgia, causing high winds and flooding rains in southern parts of the state. The storm then weakened to a tropical storm as it approached the South Carolina state line. The impact of Hurricane Idalia led to disaster declarations in several Georgia counties, with residents and businesses eligible for assistance from organizations like FEMA and the U.S. Small Business Administration.
Atlanta's vulnerability to flooding is a pressing concern, with approximately 14% of buildings in the city facing a high risk of flooding. Climate change is exacerbating the situation, increasing the likelihood and intensity of heavy rainfall events. By 2050, the annual precipitation in Atlanta is projected to rise, and the share of precipitation during downpours is expected to increase as well. These factors contribute to a heightened risk of flooding in the region.

Tornadoes in Southeast Georgia
While I could not find specific information on tornadoes in southeast Georgia, I can provide some general information on tornadoes in Georgia and how to prepare for them.
Georgia has experienced several hurricanes and tropical storms, including Hurricane Idalia, which made landfall as a Category 3 hurricane and caused significant damage in southern Georgia near Valdosta through high winds and flooding rains. Tornadoes are Georgia's number one weather-related killer, and they can develop without warning, sometimes hidden by trees or rain. They can occur at any time of the year, making advance preparation crucial.
- Develop a family communications plan, as a storm can strike suddenly when family members are in different places.
- Determine in advance where you will take shelter in case of a tornado warning. Storm cellars or basements provide the best protection. If underground shelter is unavailable, an interior room or hallway on the lowest floor possible is the best option. In a high-rise building, move to a small interior room or hallway on the lowest floor.
- You can consider building a safe room. The Federal Emergency Management Agency website offers plans for constructing or reinforcing an interior room to enhance protection.
- Contact your local emergency management agency to learn how your community sends out warnings. Warning systems vary, with some communities using sirens, while others rely on mass notification systems or media alerts.
- Stay informed about the weather conditions and follow the instructions of local authorities.
