"That can't be good," I said to my colleague Rachel, late on a Friday afternoon. The lights had flickered, dimmed twice, then recovered.
"The storm, it's getting worse. Look how dark it is outside."
She was right. Outside, the rain pummelled in gusts against the windows, and across the alley a broken downpipe spilled water, spiralling down then blowing away in the wind. The rain came in sheets between the tall buildings. Far distant in the hills, I could just see the three red lights on top of the radio towers, steadily blinking on and off.
I glanced at my screen, the power surge not quite enough to crash the computer. I had a feeling though and saved what I was working on, then clicked to shutdown.
"Just in case." I said. "I think I'll go early, get ahead of the queue for the bus."
"You're right," Rachel replied. "Me too. I'll pick Claudia up early."
As she turned to her computer, the screen went black, and the lights brightened then went out completely. "Bugger. I don't think I saved it."
"Too late," I replied. "That was a power surge. Something's gone down, big time. It's not just this building, look." Outside, it was dark. The sound of wind and rain were louder, but it was the silence inside that made the difference. "Don't take the lift," I said, "just in case the back-up power falls over. Use the stairs. The emergency exits always open."
"You go. I'll ring Claudia first, let her know I'm coming."
I waited, watching her face in the dim light. Rachel looked up, concerned, then held her phone up. "The phones are down. There's no reception."
"Come on," I said, "get your things. We're getting out of here, ahead of the rush. This is going to get worse." I turned for the door, turned back. "Switch the power off at the wall." It wouldn't make much difference, but I remembered a report saying most computer fires in government buildings were caused by power surges from the mains. And we'd definitely had one of those.
Outside our shared office, in the open plan space, staff were moving around. "Jo, use the stairs, don't use the lifts." Our project officer gathered her coat and bag and we made our way to the fire stairs. On the stairs, several like-minded people were already walking down.
