Atlantic Storm Ciaran: wind gusts of hurricane category 2-3 force, waves up to 10m, severe weather and flood risk for western Europe and Italy
A low pressure system across the northern Atlantic Ocean will head eastwards towards Europe, becoming stronger and deeper, bringing severe weather from Wednesday night to western Europe and central-eastern over the next few days with the main characteristics of strong winds, high waves and intense showers. Is one of the most powerful storms we have seen in, maybe, the last 100 years, relating to its low pressure center of 950-955 mbars accompanied by these powerful and damaging winds.

Wind gusts of a hurricane category 2 or 3 force and waves of 9-11m: the deep low pressure system is named Storm Ciaran and is a dangerous storm as it will bring strong winds between Wednesday night and Thursday to northwestern Iberia, France, the southern UK and the Low Countries. In more detail, wind gusts will reach nearly 170-190 km/h which are reaching a category 2 or 3 in hurricane wind force, while its sustainable winds will reach 120-140 km/h between Wednesday afternoon and Thursday morning southwest of the UK and west of France between the northeastern Atlantic Ocean and the Celtic Sea. Wind gusts will reach 160-180 km/h (a category 2 or 3 in hurricane force) on Thursday on the northwestern coast of France ( Brest, Cherbourg) and locally 120-140 km/h in southern Wales- England (Hugh Town, Penzance, Plymouth, Brighton, Canterbury). The strong winds will be damaging and are able to bring coastal flooding as the waves will be up to 9-11m so the coastline cities of Portugal, northern Spain, western France, the southern UK as well as Brussels and Holland should take precautions! This wind force is really unusual to see in Europe and it reminds us of the hurricanes of America, but at a lower intensity. The authorities are already warning of the damaging winds and they are preparing their houses to huddle the weather.
Severe weather and flash floods, 110-130mm in 24 in northern Italy: from Wednesday night to Thursday severe weather is expected to western Europe with intense rain, showers and thunderstorms as the Storm Ciaran will move northeastwards. The most severe weather will take place first in Iberia, France, the southern UK, while later in the Low Countries, the Alps, western Germany and northern Italy, while hail risk is also possible. On Friday, much of western and central Europe will have rain and showers, while severe weather will be expected in Italy, the Alps and the Balkans. On Friday night a new weather system will again bring unstable weather conditions to western Europe. Flash floods are possible to western Europe especially to northwestern Iberia, western France, Wales and England, while in Italy, especially between Liguria and Toscany and the northeastern regions of Italy accumulation rates will reach locally 110-130mm (Italy) in 24 hours on Thursday.
