The rain is still falling this Wednesday over much of the country.
The Nord and Pas-de-Calais are particularly concerned, leading to the risk of flooding and major floods.
Météo-France thus maintains these two departments in orange vigilance (level 3 out of 4) for the fourth consecutive day.
The floods particularly concern the Lys basin, warns Météo France.

On Monday, these floods claimed a victim.
She is an octogenarian woman.
It was found in his cellar, in Borre (North).
The place was filled with about 70 cm of water.
Since Sunday, the firefighters of the North have carried out "103 interventions, including ensuring the shelter of 171 people", said the prefecture of the Hauts-de-France region.
The recession started overnight in Merville
This Wednesday, Vigicrues explains that "the Plaine de la Lys has been experiencing a decline upstream (Saint Venant) since Monday evening".
The body in charge of monitoring the level of watercourses adds that, "further downstream, in the Merville sector, the levels remained constant yesterday for 14 hours and have finally started to drop".
The recession started around midnight.
But “the levels are still very high”.
If a "significant flood" remains "in progress", "the accumulations of precipitation forecast in the coming days should not hamper the recession too much".
The reactions to “the tributaries of the Plaine de la Lys” should remain “weak”.
But "notable overflows could persist in this basin" this Wednesday since the levels are already high.
Faced with this situation, the traditional precautionary advice applies.
Traffic can be difficult on the rails and on the road.
Power cuts can occur;
be careful with the contact of electric wires and water.
Dikes can be weakened.
Basements can be dangerous, especially parking lots.
