How Heard County floods

Tropical storms and flash flooding dominate the flood history of Heard County. Over the last 30 years, the NOAA Storm Events Database recorded 13 tropical storms, 7 flash flood events, 6 general floods, and 3 hurricanes.

Heavy rainfall from passing systems regularly creates localized hazards. For example, a persistent series of thunderstorms on February 12, 2024, brought 2.5 to 5 inches of rainfall to central Georgia, resulting in isolated flash flooding near the Alabama border. Later, on October 28, 2020, Tropical Storm Zeta swept across north Georgia, producing widespread wind damage and isolated flooding. FEMA National Flood Insurance Program records indicate that historical claims in the county are concentrated in Zone A, which accounts for 3 claims with an average payout of $1,034 and an average recorded water depth of 2 inches.

Homeowners, real estate agents, and journalists should pay the most attention to properties located within FEMA Zone A, where historical insurance claims have been filed with recorded water depths.

From the storm reports

Flash Flood · Feb 12, 2024. A period of persistent thunderstorms moved through the area with an initial warm front early in the morning and later a weak cold front overnight. Weak instability resulted in mostly benign activity, aside from a single report of each hail and wind damage. Rainfall amounts of 2.5 to 5 inches stretched across central Georgia, with highest amounts along the Georgia-Alabama line, between LaGrange and Columbus. Isolat…

Tropical Storm · Oct 28, 2020. During the late evening of October 28th through the morning of October 29th, Tropical Storm Zeta swept rapidly across north Georgia producing widespread wind damage and isolated flooding across north and portions of central Georgia. Around 1.5 million customers lost electricity for some period of time, some for several days.

Tropical Storm · Sep 11, 2017. On the morning of August 30th Tropical Storm Irma developed rapidly over the eastern Atlantic Ocean, just west of the Cape Verde Islands. Tropical Irma quickly strengthened as it moved west, reaching hurricane strength by the morning of August 31st. Hurricane Irma continued to move steadily westward across the Atlantic Ocean, intensifying to category 4 storm on the Saffir-Simpson scale as it approached the norther…

Flash Flood · Jul 20, 2014. An upper level trough continued to dominate the eastern portion of the country on the 20th, but with ridging beginning to build in aloft. A shortwave pushed across the Southeast late in the evening, sparking numerous showers and thunderstorms. Nearly stationary thunderstorms produced heavy rain over portions of Heard and Troup Counties. Rainfall amounts of 4 to 8 inches occurred primarily just southeast of Frankl…

Flood insurance in Heard County

If a building in Heard County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
