Friday, April 27th, 2007 — The Friday the 13th tornado and hailstorms caused about $100 million in damage to North Texas, four times as much as initially estimated, the Insurance Council of Texas said. That makes it the worst storm to hit the Metroplex since a spring tornado struck downtown Fort Worth and parts of Arlington seven years ago. Spokesman Mark Hanna said Thursday that 20,000 homes and 30,000 vehicles were damaged.
