1996 Nov 19 07:43 UT
NOAA-14 AVHRR Channel 4 nighttime image. This image shows Marco in its early stages. It is near the edge of the receiving range of the APL ground station. Therefore, there are regions of data loss near the bottom of this image. This is the cause of the black pixels near the edge of the scan. There is NO eye in this image. It is instead a two pixel data dropout that happens to be located in the center of the circulation. Click on the small image for a large (84 Kb) view. A very large image (186 Kb) is also available.

1996 Nov 20 23:30 UT
NOAA-12 AVHRR Channel 4 nighttime image. This image shows Tropical Storm Marco recently downgraded from Hurricane status. Marco is weakening due to strong upper level southwesterly winds shearing the convective clouds to the east of the center of the circulation. However, later during the night of November 20, deep convection redeveloped and the westerlies weakened somewhat, allowing Marco to maintain Tropical Storm strength.

1996 Nov 21 18:47 UT
NOAA-14 AVHRR 3 channel composite daytime image. The cooler clouds are white and the warmer clouds are yellow. This image shows a weakened Tropical Storm Marco with 45 mph maximum sustained winds. Marco is nearly stationary. Click on the small image for a large (140 Kb) view. A very large image (335 Kb) is also available.

1996 Nov 23 18:25 UT
NOAA-14 AVHRR 3 channel composite daytime image. The cooler clouds are white and the warmer clouds are yellow. This image shows Marco weakened to a Tropical Depression with 35 mph maximum sustained winds. Note how the higher clouds are being sheared off exposing the lower (yellow) clouds. Marco is moving west. Despite forecasts of its imminent demise, it will re-strengthen to Tropical Storm status and 65 mph winds. Click on the small image for a large (398 Kb) view. A very large image (894 Kb) is provided. A CLOSE-UP view of Marco in both large (387 Kb) and very large (832 Kb) formats is also provided.

1996 Nov 25 19:45 UT
NOAA-14 AVHRR 3 channel composite daytime image. The cooler clouds are white and the warmer clouds are yellow. Marco has re-strengthened again and now has 50 mph maximum sustained winds. Marco is moving toward the northwest. Notice the clouds associated with a cold front moving across the Gulf of Mexico from the northwest. This is expected to increase the shear and weaken Marco further. It is possible that Marco may merge with this cold front. Click on the small image for a large (383 Kb) view. A very large image (852 Kb) is also provided.

1996 Nov 26 19:35 UT
NOAA-14 AVHRR 3 channel composite daytime image. The cooler clouds are white and the warmer clouds are yellow. Marco has weakened considerably and now has 30 mph maximum sustained winds. Notice the upper (cooler) clouds are sheared off toward the northeast, exposing the remains of the circulation of the lower (warmer) clouds. A cold front is represented by the narrow band of yellow clouds stretching from northeast across Cuba to southwest (towards Yucatan). Marco appears to be merging with this cold front.
