The final data has confirmed that
#Helene's moisture plume was the most intense on record for parts of six states: Florida, Georgia, South Carolina, North Carolina, Tennessee, and Virginia.
The integrated vapor transport (IVT) associated with Helene was up to around 1.5 times higher than any previous system in this region since at least 1940.
IVT measures atmospheric moisture transport, such as with hurricanes and atmospheric rivers.
The map below highlights the record-breaking swath and quantifies how much more intense Helene's plume was than the previous record.
