DISCUSSION AND OUTLOOK
----------------------
At 1000 PM CDT (0300 UTC), the center of Tropical Depression Marco
was located near latitude 29.0 North, longitude 89.8 West.  The
depression is moving toward the west near 9 mph (15 km/h).  Marco is
forecast to continue moving westward near the coast of Louisiana
for the next day or so.

Maximum sustained winds have decreased to near 35 mph (55 km/h) with
higher gusts.  Additional weakening is expected, and Marco is 
forecast to become a remnant low on Tuesday.  The system is then 
forecast to dissipate by early Wednesday.

The estimated minimum central pressure is 1007 mb (29.74 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Marco is expected to produce additional rainfall
accumulations of 1 to 3 inches with additional isolated totals of 5
inches across portions of the north-central Gulf coast and
Southeastern United States through Wednesday. Rain totals related
to Marco near Apalachicola, Florida reached as high as 11.81 inches
on Sunday per a CoCoRaHS report. The additional rainfall may result
in areas of flash, urban and small stream flooding along the same
area.

SURF:  Swells generated by Marco are likely to affect portions of
the northern Gulf Coast overnight. These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.

TORNADOES:  A brief tornado or two remains possible overnight across
the Florida Panhandle, southwest Georgia, far southern Alabama, and
far southern Mississippi.
