T-9 minutes and Holding; Watching Storm Cell

Space shuttle Endeavour's countdown to launch has entered the final hold at T minus nine minutes, as launch control watches a storm cell tracking about twenty miles west of the Kennedy Space Center.

Chief NASA astronaut Steve Lindsey flying high in a Gulfstream II jet noted a storm cell to the west, about 15 miles from the space center.
