A warning came across the TV as Heather Irvine cleaned up after a taco dinner: Dangerous storms were on the way. Outside, tornado sirens blared, just as they had one week earlier in her Northeast Side neighborhood. Nothing had happened then, and Irvine figured nothing would happen now. Her husband, Steve had gone to visit a neighbor in their Upper Albany West neighborhood, but first had opened a window in the family room. He liked the breeze blowing through the house, especially on an unusually warm fall day such as that one Oct. 11. But the sound of the gusting wind alarmed Heather, so she went to shut the window. That’s when she saw dirt and mulch flying in circles outside. The wind growled louder and louder.
