3. In the event of a network crisis, such as geopolitical conflicts, health crises or natural disaster, which prevents the issuing of reliable traffic forecasts, the transitional provisions adopted by the Commission in accordance with paragraph 2 may include the temporary suspension or adaptation of the performance scheme until the network crisis ends and the new reliable forecasts are available. In such a case, the Commission shall define the relating conditions, including necessary adaptations to applicable charges, in the decision referred to in paragraph 1.
