* WHAT...For the Coastal Flood Advisory, minor coastal flooding. 
  For the High Surf Warning, dangerously large breaking waves of 
  6 to 10 feet in the surf zone. For the High Rip Current Risk, 
  dangerous rip currents.

* WHERE...Mobile Coastal and Baldwin Coastal Counties.

* WHEN...For the Coastal Flood Advisory, until 1 PM CDT this 
  afternoon. For the High Surf Warning, until 7 PM CDT this

* IMPACTS...Flooding of lots, parks, and roads with only 
  isolated road closures expected. Breaking waves can sweep 
  people off jetties and docks, and into dangerous seas. Life-
  threatening swimming conditions and significant beach erosion 
  can be expected. Rip currents can sweep even the best swimmers 
  away from shore into deeper water.

* ADDITIONAL DETAILS...Water levels of 1 to 3 feet above normally
  dry ground will continue through early afternoon. 

* ADDITIONAL INFORMATION...High water impacts significant 
  portions of Shell Belt and Coden Belt Roads, can result in 
  limited travel and some full closers.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.

Everyone should remain out of the water due to life-threatening
surf conditions. Stay off of jetties, piers, and other waterside
infrastructure.

Swim near a lifeguard. If caught in a rip current, relax and
float. Don't swim against the current. If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.

NEAR TERM...
(Now through Thursday night)
Issued at 454 PM CDT Tue Sep 10 2024

Tropical Storm Francine currently over the west central Gulf is
forecast to move northeastward and strengthen to a hurricane
before making landfall along the Louisiana coast on Wednesday or
Wednesday night. This system will bring a number of impacts to the
area including a high risk of rip currents, high surf, locally
heavy rains and a risk of flash flooding, coastal flooding, and
the potential for tornadic activity. For tonight, will have likely
to categorical pops for the coastal counties and much of
southeast Mississippi with lesser pops further inland. Have gone
with categorical pops for the entire area on Wednesday and
Wednesday night, then rain chances gradually taper off from west
to east Thursday into Thursday night as drier air is ushered into
the area. Rainfall totals during the period look to range from 2
to 6 inches, with the higher amounts mostly anticipated over
southeast Mississippi and much of the coastal counties, and a
Flash Flood Watch has been issued for this portion. Plenty of
favorable shear and improving instability will support a potential
for tornadic activity for the entire area mainly from late
Wednesday afternoon into Thursday morning (then tapering off), and
the highest potential looks to be over the coastal counties and
extreme southeast Mississippi. A High Risk of rip currents
continues through Friday, and a High Surf Advisory has been issued
from Wednesday evening through Thursday evening for surf heights
of 6 to 8 feet. A Tropical Storm Warning is now in effect for
Stone and George counties in southeast Mississippi and Mobile and
Baldwin counties in southwest Alabama where wind speeds or wind
gusts will likely reach tropical storm force (39 mph). A Tropical
Storm Watch is in effect for Perry and Greene counties in
southeast Mississippi where winds or winds gusts may reach
tropical storm force. A Storm Surge Watch is in effect for coastal
Alabama for potential inundation of 2 to 4 feet, and a Coastal
Flood Advisory is in effect for the western Florida panhandle for
inundation values of 1 to 2 feet. Lows each night typically range
from the mid 60s well inland to the lower/mid 70s near the coast.
Highs on Wednesday range from the mid 70s well inland to around 80
near the coast, then Thursday will be warmer and range from
around 80 well inland to the mid 80s closer to the coast. /29

LONG TERM...
(Friday through Tuesday)
Issued at 454 PM CDT Tue Sep 10 2024

A drier airmass moves over the Southeast in the wake of Francine.
Temperatures rebound quickly to around seasonal norms, with little
cool air moving over the forecast area (due to southwest to
westerly flow in Francine's wake). High temperatures in the mid to
upper 80s and low temperatures in the mid 60s to low 70s are
expected. A dry forecast over the weekend sees a return of mainly
isolated rain showers and thunderstorms in the coming week, as
moisture creeps back north over the Southeast in the coming week.

MARINE...
Issued at 454 PM CDT Tue Sep 10 2024

A Tropical Storm Warning is in effect for the Alabama marine area,
and a Small Craft Advisory is in effect for the western Florida
Gulf waters. Winds and seas diminish Thursday into Thursday night,
with a light to moderate westerly flow expected for Friday. Winds
and seas will be higher near storms. /29
