Learn French: Compte tenu de la tempête, le littoral est évacué. - Considering the storm, the coastline is evacuated.

Compte tenu de is a formal preposition meaning "considering" or "taking into account". Unlike parce que, which must be followed by a full clause with a subject and verb, compte tenu de is followed directly by a noun (la tempête). It introduces an established, objective fact that justifies the action.

Does the tenu in compte tenu de ever change to match the noun that follows it?

No, compte tenu de acts as a fixed prepositional phrase here, so it is invariable. Even though la tempête is feminine, tenu does not take an extra -e.

What if the sentence were about multiple storms? Would the de change?

Yes. Because compte tenu de ends with the preposition de, it follows the normal contraction rules. If we were talking about multiple storms (les tempêtes), de and les would contract to make compte tenu des tempêtes.
