Hurricane Earl



Track maps

Aug 30 SST Track Map
Track superimposed on sea surface temperature (SST) derived from averaging images over 3 days ending August 30 in order to remove cloud cover.
Note how Earl intensified over the warmer water near the coast.

Sep 6 SST Track Map
Track superimposed on sea surface temperature (SST) derived from averaging images over 3 days ending September 6 in order to remove cloud cover.
Note the cool wake left by Earl that has now drifted east of its track.

1998 September 1 09:13 UT
NOAA-14 AVHRR channel 4 nighttime image. A closer view (231 Kb) is seen by clicking on this small image. Earl is now a tropical storm with 40 mph winds. The disorganized appearence of Earl in this image makes it difficult to identify a center. Earl is nearly stationary at this time.

1998 September 2 00:06 UT
NOAA-12 AVHRR 3 channel composite late evening image. A closer view (215 Kb) is seen by clicking on this small image. The maximum sustained winds are now about 60 mph. Earl appears a little better organized in this image than at 0913 UT on 1 September. As a result of a shift in the area of deep convection, the center has recently reformed to the northeast of its previous position.

1998 September 2 09:01 UT
NOAA-14 AVHRR channel 4 nighttime image. A closer view (315 Kb) is seen by clicking on this small image. Due to Earl's disorganization, the location of the center of the storm is uncertain. Consequently, observations from aircraft and satellite are not in agreement. The data from dropwindsondes suggests that Earl is a shallow system that is not responding to deep layer steering.

1998 September 2 12:20 UT
NOAA-12 AVHRR 3 channel composite morning image. A closer view (354 Kb) is seen by clicking on this small image. The cooler clouds are white and the warmer clouds are yellow. It is apparent in this image that Earl is becoming better organized. A very large image (753 Kb) is also available.
