The New York Times has an article about St. Louis' vulnerability to extreme weather in the context of the tent that blew over Saturday.
I found this quote from a St. Louis resident to be interesting:
“Normally, people’s reaction to tornado sirens, they think it’s somewhat benign because they go off all the time,” said James Dixson, 37, who works in marketing and lives downtown. “So when there’s a more serious occurrence, we hear it and don’t actually react.”
This is exactly what I feared last May when I criticized local St. Louis emergency management for overuse of sirens far away from any threat (video below):
Misuse of sirens is an increasing problem as I discuss in When the Sirens Were Silent my new book that is on its way to bookstore shelves.
