21. Plate 11 shows the comparison of observed and computed pressures at 
Galveston, Texas. Plate 12 shows the comparison of observed and computed 
pressures at Alvin, Texas. These stations were the two closest to Alicia's 
track immediately after landfall. Plate 13 shows the computed barogram at 
the site of T-14 near Baytown, Texas. Plate 14 shows both the compensated 
and uncompensated hydrographs from the T-14 location. 
Wave and Tide Data 
22. During Alicia's passage through the Gulf of Mexico, CERC was 
operating wave and tide gages on three Shell Oil Company petroleum platforms 
off the south Louisiana coast. The locations of the platforms are shown in 
Figure 3. The positions and nominal water depths of the platforms are:
