At least five states are preparing for severe rain this Friday, July 24.
The National Weather Service has issued a warning for Alabama, Georgia, North Carolina, South Carolina, and Tennessee about a slow-moving thunderstorm with intense rainfall rates of 2-2.5 inches per hour. This storm could cause flash flooding in these places.
“Total PWat values of 2 will slightly increase toward 2.25, and deep layer steering flow will remain slightly confluent (increasing to ~20 kts) but mostly west to east to allow for localized repeating/training especially as the CAD erodes and the front lifts but remains fairly parallel to the mean flow,” the National Weather Service said.
“Isolated spots of 2-3.5″ remain possible, but most should fall quickly and in the range of 1-3 hr FFG values, suggestive of widely scattered incidents of focused/localized possible flash flooding.” This would only increase in potential if cells could intersect in prone urban areas, particularly Birmingham and Atlanta.
