... New information...
at 330 am CST... the center of poorly defined Tropical Storm Ida was
located near latitude 29.8 north... longitude 88.4 west... or about 30
miles south of the west end of Dauphin Island Alabama. Ida is now
moving to the north-northeast near 11 mph. Ida will make landfall
very near the Alabama/Mississippi border near sunrise. After
landfall... Ida is expected to turn more to the east. Data from an Air
Force Reserve hurricane hunter aircraft and the WSR-88D in Mobile
Alabama are in agreement that maximum sustained winds are near 50 mph
with higher gusts. Ida continues to weaken.
... Winds...
the wind threat is on the wane as Ida weakens. Wind speeds between 30
and 45 mph... with higher gusts... will continue to occur during the
morning hours... mainly along the coast. This afternoon will be windy
as dry air mixes into the back of Ida from the west. This may cause
frequent gusts to near tropical storm force.
... Storm surge and storm tide...
as Ida approaches coastal Alabama... area tide gages have continued to
show a rapid rate of increase in high water values since just after
midnight. Given ida's current location... southeasterly surface winds
are now pushing water onshore in the form of surge from the mouth of
Mobile Bay eastward... including the upper reaches of Mobile Bay and
adjacent rivers. Winds are beginning to turn northwesterly and blow
offshore on the Mississippi coast which is a sign that some help is on
the way in the next few hours as far as water recession from Bayou La
Batre over to Fort Morgan... but again... this will take a few hours.
... Inland flooding...
a Flash Flood Watch remains in effect and may be revised or canceled
later today. The area most likely to receive excessive rainfall will
be east of a line from Evergreen Alabama to Andalusia to Crestview.
... Coastal hazards...
moderate beach erosion is expected to occur from the west end of
Dauphin Island Alabama to Destin Florida. Extremely dangerous rip
currents will occur along the Alabama and northwest Florida beaches
through Tuesday afternoon due to high winds and waves. Rip currents
are life-threatening to anyone entering the surf... and swimmers
should not enter the water under any circumstances.
