Today is the anniversary of Houston’s worst tornado outbreak that occurred in November 1992. The unusually powerful storm system produced six tornadoes in Harris County alone, with three of those tornadoes on the ground at the same time: An F2 that touched down near Rice University, an F3 near Lake Houston, and the only F4 in Harris County's history tearing through Channelview. | ABC13 Houston
