DISCUSSION AND OUTLOOK
----------------------
At 400 AM CDT (0900 UTC), the center of Post-Tropical Cyclone Marco
was located near latitude 28.8 North, longitude 91.2 West. The
post-tropical cyclone is moving toward the west near 10 mph (17
km/h), and this general motion is expected to continue for the 
next day or so. On the forecast track, Marco should continue moving 
westward just offshore the coast of Louisiana until the system 
dissipates.
 
Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Additional weakening is expected, and Post-Tropical Cyclone Marco 
is forecast to dissipate by early Wednesday, if not sooner.
 
The estimated minimum central pressure is 1008 mb (29.77 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
SURF:  Swells and rip currents affecting the north-central Gulf
coast will gradually subside today.  Please consult products from
your local weather service office.

Post-Tropical Cyclone MARCO Forecast Discussion

Post-Tropical Cyclone Marco Discussion Number  21
NWS National Hurricane Center Miami FL       AL142020
400 AM CDT Tue Aug 25 2020
 
Marco has been devoid of any significant convection for at least 
12 hours, and ASCAT scatterometer surface wind data around 0239Z 
suggested that Marco might have degenerated in a north-to-south 
elongated trough. Based on this information, Marco has been 
downgraded to post-tropical remnant low.  Brisk southwesterly 
vertical wind shear of 30 kt is forecast to increase to near 35 kt 
in 24 hours, which should prevent the redevelopment of deep 
convection near the center.
 
Marco's remnants are expected to move generally westward along or 
just south of the southern coast of Louisiana for the next 24 hours 
or until dissipation occurs.

This is the last forecast/advisory issued by the National Hurricane 
Center on Marco. Additional information on this system can be found 
in high seas forecasts issued by the national weather 
service...under AWIPS header NFDHSFAT1 and WMO header FZNT01 KWBC.
