The road project had never really finished.

She took a photograph of the technician’s report and attached the original work-order number to her incident log. It would be tempting, later, to say that nobody could have seen the failure coming. She had seen a piece of it. So had the technician. They had just never been given an answer that matched the seriousness of the warning.

At the high-school shelter, the absence of the siren had a different shape.

A volunteer named Grace Patel was sorting wet coats when a woman from Maple Street came up to ask whether she could borrow a phone. The woman was holding the hand of a boy with bright red glasses.

“We didn’t know,” she told Grace. “The phone made a noise, but I thought it was one of those weather warnings that comes for the whole county. My sister heard somebody knocking and got us outside. My mother was waiting for the siren.”

“Is your mother here now?”

“Yes. She’s sleeping.”

Grace held out a charger. The woman took it with a hand that would not stop shaking.

Across the gym, Mr. Harris had found a folding chair beside an electrical outlet and was guarding it for anyone who needed to charge a medical device. Alma Jenkins had placed her empty birdcage on the table, and three children were taking turns pretending it housed an invisible parrot with very rude opinions.

Nobody was thinking about the wording of an equipment contract. They were thinking about clean socks and whether insurance would pay for a mattress. They were thinking about the last thirty seconds they had spent in a hallway deciding what to carry.

A small argument broke out when a shelter volunteer announced that families might not be allowed home for another night. Loretta Mercer stood from her cot, walked to the supply desk, and asked whether someone could post an updated list of buildings already inspected.

“The county hasn’t sent it,” the volunteer said.

“Then call them,” Loretta answered. “People don’t get calmer because nobody tells them anything.”

The volunteer had the exhausted look of someone doing more than one person’s work. Loretta saw it and softened her voice.
