Flash Flood · Aug 16, 2025. Thunderstorms developed in a highly unstable environment along a lingering boundary from a MCS that moved through the night before. Weak flow led to slow moving storms, propagating slowly along an outflow boundary. With precipitable water exceeding 2 inches and high soil moisture, this led to flash flooding near the Savannah River.
Flash Flood · Sep 27, 2024. Tropical Storm Helene formed in the NW Caribbean Sea on September 24. Helene moved northward into the Gulf of Mexico where it strengthened into a hurricane on September 25. Helene made landfall as a major hurricane in the Big Bend area of Florida the night of September 26 before quickly moving inland into east central Georgia by early morning on September 27. Helene weakened to a strong tropical storm and produced…

Flash Flood · Jul 7, 2020. An upper trough, along with a very moist atmosphere, contributed to a band of heavy showers and thunderstorms that set up in an area of low level moisture convergence just east of a slow moving surface low, leading to heavy rain and flash flooding. Rainfall amounts of 4 to 6 inches, most of which fell over the course of a few hours, led to some roads flooding and washing out. Water entered some homes, and some pe…

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Edgefield 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.
