Real Florida lives with hurricanes. Whether Leonida has them as a mechanic is a real open question. We don't commit to an answer.

Why this is speculative

Trailer 2 shows storm imagery. It does not show 'hurricanes' as a labelled or repeating mechanic. Rockstar has not used the word 'hurricane' in any official statement.

What's plausible: storm-coded story moments. What's less plausible but possible: dynamic hurricane events that recur during gameplay.
