* The images above show the Sea Level Pressure and 500 millibar (mb) analyses every 6 hours from 0000 UTC October 27, 1991 through 1800 UTC November 2, 1991.

* The animation on the left shows the Sea Level Pressure (white contours) and the 925 mb winds. Pressure is in mb, and contoured every 4 mb. Winds show direction and speed, with speed represented by the plotted barbs on the symbol (half barb=5 knots, full barb=10 knots, flag=50 knots).

* The animation on the right shows the 500 mb heights (in decameters), contoured every 6 decameters (60 meters).
