Crisis talk is the most demanding communication we can imagine. In addition to the content itself, it is important to convey calm and confidence. In addition, since people are often in a state of fright during the crisis, it is necessary to come into the action through communication. So the language has to be verbs-enriched.
My recommendation for the crisis: Speak clearly, verbally and without the subjunctive. Short sentences, a lot of action and no unsettling words like could-would-possibly.
