The new intense Mediterranean episode this Sunday placed the Alpes-Maritimes department on RED alert and brought between 50 and 100 mm of rain to the Paillons watershed, where the ground was already saturated due to six weeks of successive storms. These new rains have raised the precipitation level in the watershed to 800 mm since mid-October, while the annual average in Nice is 750 mm.
Work had to be suspended as early as Sunday morning to ensure the safety of the workers.
This Monday, the recession of the Paillon is being monitored by the Metropolis services.
A new work schedule should allow for the reopening of the Pénétrante to traffic by the end of the week.
