Floods in SE France, NW Italy 4th-6th November

Coles · 04-11-2011 6:04pm #1

There seems to be a risk of quite severe flooding in SE France over the coming weekend.

Here's a couple of resources for anyone who is interested in keeping an eye on the situation as it develops.

Meteo France. An orange alert in place at the moment.

French river gauges and warning system.

Netweather. Select 'North Atlantic Precipitation' and toggle through the +3, +6 etc to see the intensity of the forecasted rain in the hours ahead.

Post up any other good resources.

Wow! Part of meteofrance's warning put through google translate:

"The Cevennes massif (Hérault, Gard, Lozère and Ardèche), the rains will intensify during the night. They will continue during the day Saturday. By Saturday night is still pending the accumulation of additional rain expected over the Cévennes reach 150 to 200 mm or 250 mm very occasionally. Of rainfall on the episode will then reach the Cevennes relief from 350 to 500 mm and may be around 600 to 800mm in particular in the vicinity of the Aigoual."
The 600mm-800mm predictions are for the highest parts of the massif central region but they are still very high totals!

This site is excellent for severe convective events. They have daily forecasts along with more frequent updates (if you click on "fils infos" on the right) when there is severe weather occuring.

Looks like the Italian Alps are going to get battered as well, 200mm widespread over the next 3 days and probably much higher on the mountains. Basically the equivalent of the rain Dublin got for 6 hours lasting for 3 days continuously!

Rivers are already looking very high in the south..going by the tags on the video I think this is the Hérault river which flowing through the town of Adge.

If that falls as snow on the alps, it could be a very good skiing season!

Looks like the worst of the Italian rain will fall north of Turin.

I'll adjust the thread title.

Hope my family are OK, my mum lives in Lyon, where only the quays flood really, but my sister and other family are at the border of Ardeche and Drome. They got bad floods there I think it was 2/3 years ago... the rivers are down to a stream in the summertime, and can reach ridiculous proportions when thunderstorms happen. Because it doesn't happen that often, it's not really worth their while doing the works to contain them (no flood walls for a practically dry riverbed 7/8 months of the year !).

A facebook friend who lives in Vaison la Romaine recently posted this video, since it was the anniversary of one of the most lethal and destructive floods this area ever experienced. 37 people died that day. This is further away in the mountains, in the Vaucluse area, which is prone to heavy cellular storms.

Let's hope there won't be anything as serious.

Some sort of developing mediterranean hurricane

Certainly looks like some sort of sub-tropical system alright. All the indications are that it's warm core and models indicate a contracting windfield around the centre as it meanders over the next few days. Interesting to keep an eye on. Well spotted!

At 18 seconds what is that black 'yoke' going against the flow really fast?

By blurry white circle you mean umbrella right?

Mountainsandh · 09-11-2011 8:20am

oh...

I hadn't seen an umbrella. Hadn't even occured to me it could be one, doh.

Genoa is quickly recovering (apart the most affected streets) from the disastrous flood, thanks to the thousands of youth, students, who are spending these days working voluntarly in the mud to help people who suffered big damages and lost almost everything (homes, shops, etc.), they have been called 'mud angels' and are doing a great job
