We consider the consequences of the fire destructions, happened on April 15th, 2019, on the static regime of the Cathedral Notre Dame of Paris. In particular, we ponder the effects of the wind on the stability of the Cathedral at its post-fire state and compare them with those calculated, with the same numerical model and assumptions before fire. We show that a major consequence of the fire destruction is the considerable reduction of the wind strength of the Cathedral.
