France: Flood warnings in place in areas of northern France as of Feb 10.

Authorities have issued orange flood warnings (the second highest on a three-tier scale) in the Finistere and Pas-de-Calais departments of northern France as of early Feb. 10. The Pas-de-Calais region, in particular, has been experiencing heavy rainfall since Feb. 7, with limited flooding reported Feb. 8 after the River Canche burst its banks., with the river remaining under orange warning. In Finistere, strong winds and continued rainfall are forecast. The River Laita has been placed under an orange warning for flooding, while a yellow flood warning has been issued for the Aune and Odet rivers. Officials could update and possibly extend the coverage of weather alerts over the coming days.

Further sustained heavy rainfall could trigger further flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where heavy rainfall has saturated the soil.

Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.

Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Severe weather could also trigger flight delays and cancellations at regional airports. Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas that see heavy rainfall and potential track inundation.

Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites. Disruptions triggered by inclement weather and resultant hazards, such as flooding or avalanches, could persist well after weather conditions have improved; it could take days before any floodwaters recede and/or officials clear debris. If there is severe damage to infrastructure, repair or reconstruction efforts may result in residual disruptions.
