Characteristic of heat waves, the nights are hot, with temperatures that will not go below 19 ° C to 23 °, even 25 in large cities. In Paris, it was 22.6 ° C Tuesday at 5am. Above 20 ° C, meteorologists speak of “tropical night”.
Alternate circulation, brevet deferred
While the peaks of ozone pollution are favoured by the heat, the Minister of Ecological Transition François de Rugy announced a reform of the triggering of differentiated traffic in Ile-de-France, “automated” in case of exceeding the limit thresholds for air pollutants.
This new device could be tested very quickly since the mayor of Paris Anne Hidalgo asked the prefect of police this differential circulation for Wednesday, which according to Airparif should see the “threshold of information of the public” reached for the pollution to the ozone.
On Monday, the government announced the postponement of a few days of the college brevet tests that were to take place on Thursday and Friday, to “ensure the safety of students.”
From the middle of the week, records will be established for a month of June or “locally all months”. The hottest day will be Thursday or Friday.
The heat wave, which involves at least three days and three nights beyond a certain temperature threshold (different depending on the region), should extend beyond the weekend at least over a large half of the south-east, according to Météo-France. No region should be spared, including the northwest at the end of the week.
“Heat islands”, cities suffer particularly, because of concrete soils, the lack of trees and the intensity of human activities.
The authorities remind people of the need to drink water regularly, to wet the body and to protect the skin. The information platform “Canicule info service” is available on 0800 06 66 66 (toll-free number).
Everywhere we organize, including spectators and teams of the Women’s World Cup (caution messages to the first, special drinks for the seconds).
Farmers must be vigilant for the health of their animals. Others fear that drought will affect fodder.
For SNCF and RATP, this heat involves closely monitoring equipment and infrastructure, including power cables, catenaries and tracks.
In the building industry representatives announced the shift in the hours of workers.
Cafeterias, on the other hand, smile, with a foreseeable increase in turnover of at least 30%.
Consumption of electricity will be “important”, has already warned the manager of the high voltage network RTE, which expects a “potential peak of summer consumption Thursday at 13h,” without fear, however, a supply disruption.
With global warming, scientists anticipate heat waves two to three times more numerous by mid-century.
