Drought Monitor

A plume of tropical moisture moved northward across the Gulf of Mexico and brought heavy rains to portions of Alabama, Florida, Louisiana and western Georgia.

The rains prompted some trimming of each drought level across southwestern Alabama and extreme western Florida.

Extreme drought was removed from Okaloosa and Santa Rosa Counties in Florida.

As a result of isolated convective rains (1.0 - 2.4 inches), reductions in the coverage of drought conditions were also pursued across west-central Georgia and eastern Alabama.

Across northeastern Florida, the rains missed the areas already under severe or extreme drought, so D4 (exceptional drought) was expanded to cover St. Johns county.

Additional expansion of D3 (extreme drought) was included over Flagler County.

Southeast Region
Standardized Precipitation Index (SPI) values for the past 3 months indicate moderate drought, but SPI values keyed to longer periods of record (6, 9, and 12 months) all indicate extreme or exceptional drought across this region.
