Situation
The western heat wave is slowly starting to ease as more ocean air moves in, but Wednesday into Thursday night will continue to be challenging in many areas.
This Wednesday, July 15, the storms intensify, especially from the massif central to the central-east, with the risk of hail, heavy rain and strong gusts of wind.
On Thursday the degradation will spread from the southwest to the northeast, with the atmosphere still heavy and very hot. Other developing warnings will affect many other departments this weekend.
?
A moderate drop in temperatures will become widespread on Friday, marking the end of a heatwave across much of the country.
However, the southeast will continue to experience very intense heat, and the drought will continue to leave the risk of fires high.
