August 2022 Brings Excessive Rain to Much of The Central Gulf Coast

Rainfall Totals Add Up Over Central Gulf Coast
August 2022

August 2022 was anomalously wet over the central Gulf coast with rain gauges over several areas measuring over a foot of rain for the month. A notable mention is these rains occurred without the influence of a tropical system. The map below shows a Graphical Information System (GIS) representation of the distribution of rainfall from nearly 180 rainfall reports received by the National Weather Service Mobile/Pensacola over the County Warning Area (CWA).

Two additional graphics of the Areal Rainfall Distribution are provided in the tables below. Areal Rainfall Distribution without observations as a layer (Fig. 1) and County Averages (Fig. 2)

The following two graphics highlight the excessive rainfall from August 2022 in a climate frame of reference using radar rainfall estimates. Fig. 3 shows the rainfall for much of the area was between 4 to 8 inches above normal and Fig. 4 shows between 200 and 400% of normal rains fell.
