SUMMARY
DISCUSSION

There are no coastal watches or warnings in effect.


SURF: Swells and rip currents affecting the northcentral Gulf coast will gradually subside today. Please consult products from your local weather service office.


At 400 AM CDT (0900 UTC), the center of PostTropical Cyclone Marco was located near latitude 28.8 North, longitude 91.2 West. The posttropical 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 PostTropical Cyclone Marco is forecast to dissipate by early Wednesday, if not sooner.

The estimated minimum central pressure is 1008 mb (29.77 inches).


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
