This is a new concern for communicators: how to communicate when everything is down, due to water, freezing temperatures or wind, for example. Our witnesses recently experienced all three at the same time.

Their story echoes that of Sterenn Grall-Lavenir, territorial marketing and communications manager for Brest, in Brittany, which was severely affected by Storm Ciaran.
