Weather Warning Bulletin East Zone published on Saturday June 29, 2024 at 4:02 p.m.
Current situation :
The forecast is confirmed.
General situation:
Remarkable stormy episode reaching the south of the Burgundy-Franche-Comté region late Saturday afternoon. These storms accompanied by potentially violent phenomena then spread towards the Grand-East during the evening and night from Saturday to Sunday.
Observations notables :
The heat that precedes the storms is very present in the region this Saturday afternoon. In particular, we note 30.4°C in Dijon (21), 31.4°C in Mâcon (71), 32.0°C in Remiremont (88), 32.2°C in Dole (39) and Colmar-Meyenheim (68).
Expected development:
A structured and well-organized stormy degradation approaches the south of Burgundy at the end of the afternoon. It then spreads rapidly towards Franche-Comté and the Grand-Est from 7:00 p.m. to 8:00 p.m.
This remarkable stormy episode is accompanied by locally violent phenomena, particularly in the event of the formation of stormy supercells or organized line structures:
– wind gusts sometimes greater than 100 km/h, up to 120 km/h possible very occasionally
– significant accumulations of precipitation in a very short time (locally 40 to 50 mm in less than an hour and up to 80 mm in a few hours)
– risk of large hail with locally hailstones with a diameter greater than 5 cm
– intense electrical activity.
This marked stormy area then gradually evacuates through the north-east of Lorraine and Alsace after midnight. Behind, less virulent storms may still occur until Sunday 4 a.m. For the rest, stormy rains remain in the news until mid-Sunday morning.
