Brisbane Valley Supercell Hailstorm

November 4, 2002

The original line of storms can be seen developing S of Toowoomba early in the afternoon.  This line then moves northwards, of which two cells become dominant, one north of Gatton and another just NE of Toowoomba.  These two merge and become the supercell that moves NE.  The supercell splits, one moves slowly north while the other moves NE.  Several other storms keep developing behind it and move across the Brisbane Valley.
