Alert period and area
The period lasts until Monday morning and everything comes down relatively quickly. The area extends from Ticino to Slovenia and in the Maritime Alps to the Hautes Alpes and their south-western foothills. On the main Alpine ridge in Switzerland and in other parts of France, it can also be close to the alarm.
Snowfall line
This is relatively high and fluctuates between 1500 and 1800m, it may also rain briefly up to 2000m, especially on the Hautes Alpes or where there are slight SW foehn effects. With the strong spring sunshine and not quite as high precipitation intensity, I would doubt whether there will be snow further down in the Alps, as it won't cool down that much.
