I went to school at Apex High, and know lots of people in the area. One of my family's good friends lives near the plant (1/4 to 1/2 of a mile), and she is unable to drive due to a disability. We haven't heard from her, so hopefully one of her friends came to pick her up to get her out of harm's way. There's apparently a toxic gas cloud over the city, so hopefully nothing bad will come of that. The current rain appears to be helping in that regard.
This entire event reminds me of a scene from The Simpsons (from episode 2F32, 'Round Springfield):
Lisa returns to KJAZZ with the album, and the DJ puts it on a turntable and hands her a radio. "Here, you can listen to it on this," he says, but as she walks away from the station, all she picks up is static. She sighs heavily, "I did the best I could, Bleeding Gums." Just then, a large cloud appears over the radio tower and lightning strikes it. Suddenly, the signal comes in clearly -- for Lisa, Homer at home, Abe at the Castle, and Wiggum in his patrol car. "Attention all units, attention all units, poison gas cloud heading for --" announces the dispatcher, but her voice is cut off by the jazz transmission. Wiggum approves until he passes out from a cloud of poison gas.
