The threat for heavy rainfall and flooding will shift west into the Central Gulf Coast region today.
The low that was situated over Northern Florida has moved further west overnight and will continue to do so today. This low is expected to interact with a surface trough and another feature located just south of Mobile Bay over the next several days.
All three of the aforementioned features working in conjunction with each other will bring heavy rainfall to the Central Gulf Coast region over the next 2 – 3 days beginning today.
Rainfall totals have been adjusted slightly downward today. Currently the highest rainfall accumulations of 8 – 10″ are forecast across Southeast Louisiana. Accumulations of 6 – 8″ are expected from Panama City, to Gulf Port, Mississippi, and as far North as Hattiesburg, Mississippi. Some locally higher amounts will be possible where stronger cells move through.
These rainfall totals will likely lead to flash flooding and river flooding across the Central Gulf Coast where the higher rainfall totals occur.
As a result, flash flood watches are in effect across much of the Central Gulf Coast region. For information regarding watches and warnings for your local area you should check with your local National Weather Service office.
The low should then lift north out of the Central Gulf Coast region by Friday night or Saturday; and the surface trough and low should dissipate or follow lift north as well. This will allow things to dry out across the Gulf Coast by this weekend.
We will have another update out tomorrow.
