September 26-30, 2024 Hurricane Helene

Hurricane Helene developed in the northwest Caribbean Sea on Monday, September 23, 2024, as Potential Tropical Cyclone Nine, before moving northward into the eastern Gulf of Mexico and strengthening into a Category 4 hurricane. Helene then made landfall in the Florida Big Bend on Thursday, September 26, 2024, before continuing northward and weakening across Georgia, northwest South Carolina, western North Carolina, eastern Tennessee, and Kentucky. Helene brought devastating wind damage and catastrophic flash flooding to these areas before merging with an upper level low centered over the Tennessee and Ohio Valleys. The former hurricane continued to linger across the region for several days before finally ejecting off to the northeast on Monday, September 30.

Across Middle Tennessee, Helene brought widespread heavy rainfall of 2" to 6" over a four-day period from Thursday, September 26 to Sunday, September 30. Many areas received more rainfall in these few days than they typically see in the entire month of September. Due to the ongoing drought across the region, however, this rainfall did not result in any notable flooding across Middle Tennessee. The weakening hurricane also brought gusty winds up to 45 mph at times to the midstate, which resulted in a few downed trees and power lines, as well as scattered power outages with up to 10,000 people out of power - mainly in the Nashville metro area. The low pressure associated with Helene also brought record low readings to the area for the month of September, with Nashville setting its 9th lowest pressure on record.
