A slow-moving storm system will bring multiple days of severe weather to parts of western Europe this week.
The area of greatest risk remains from France into Belgium, Netherlands and Germany from Wednesday afternoon into Thursday.
On the southern side of the storm, gusty showers and thunderstorms were seen across Portugal and Spain on Tuesday night into Wednesday, but no widespread severe weather was reported.
As a warm front lifts across France, the threat for severe weather will increase in western and northern France on Wednesday afternoon and evening.

Across western France, downpours will result in the threat for flash flooding while the strongest thunderstorms will be capable of producing damaging winds and hail into Wednesday evening. An isolated tornado cannot be ruled out.
Farther north and east, rainfall will increase during the afternoon. Around Paris, the greatest threat for severe weather will be during the late afternoon and evening hours. Again, heavy rain, damaging winds and hail will be possible.
This same threat will exist across Belgium and Netherlands where thunderstorms will rumble late on Wednesday into Wednesday night.
The threat for severe weather will diminish overnight on Wednesday and Thursday morning before another round of potentially severe thunderstorms will erupt on Thursday afternoon into Thursday night from eastern France into western and southern Germany.
Once again, the storms will be capable of producing torrential rainfall, damaging winds and hail.
Showers and thunderstorms will continue across western and central Europe from Friday into the weekend, but no widespread severe weather is expected at this time.
Ahead of this storm, unseasonable warmth and high humidity will prevail from Germany and Switzerland eastward across Europe with temperatures 5-10C (9-18F) above normal.
