The scene
It is Monday afternoon. At 3:08 a tornado warning is issued for Tiberius County, take cover is sounded, and everyone shelters. The all-clear comes at 3:20. Building B night shift is on, Building A is in, and Building C is open until 3:30. Utility power is out and GEN-1 is running. At 3:25, a maintenance mechanic walking the south side of Perry's Awesomeness Factory, Building B, finds a light pole down across transformer TX-2. TX-2 is tilted and leaking transformer oil from a seam. About 20 gallons are floating on rainwater inside the pad curb, and the rainwater is about 6 inches deep. A power line is down across the South Drive near SI-2. Building C's headcount is one driver short, last seen in his tractor in the yard. The storm has passed. It is 66 degrees and overcast, with the wind from the northwest at 15 miles an hour.
