Tropical Depression Marco Discussion Number  20
NWS National Hurricane Center Miami FL       AL142020
1000 PM CDT Mon Aug 24 2020

Visible imagery and surface observations indicated that Marco made
landfall around 6 pm CDT near the mouth of the Mississippi River.
Shortly before landfall, reports from an Air Force Reserve Hurricane
Hunter plane indicated that Marco was still producing a small area
of tropical-storm-force winds over water to the northeast of its
center. Since then, the system has moved almost due west along the
southeast coast of Louisiana while its deep convection has become
farther displaced from the low-level center. Between the lack of
central convection and Marco's proximity to land, it is likely that
the winds have decreased since earlier this evening and the
intensity has been lowered to 30 kt.

If deep convection does not redevelop overnight, Marco will become a
remnant low as soon as Tuesday morning. Regardless of its status,
Marco should move generally westward near the coast of Louisiana
while it weakens for the next day or so and could continue to
produce heavy rain for portions of the north-central Gulf Coast
tonight. The system is then forecast to dissipate by early
Wednesday, if not sooner.
