Storm Ciaran is also bringing strong winds to parts of France, including the northwestern coastline. Cornish weather team issues second-ever severe weather warning
"Storm Ciarán is going to be strongest windstorm so far this season, it'll unleash heavy rain and intense winds for most of Cornwall and the Isles of Scilly." It said it is"crucial" for people to stay away from the seafront as"high tides and strong waves are extremely dangerous". These are associated with areas of rapidly deepening areas of low pressure and will be best remembered from the storm of 1987.Mostly they affect an area of only 30 miles across and are of a fairly short duration; three to four hours.Parts of Northern Ireland have already seen severe flooding, with fields and streets underwater.
Within this process, Ciaran will see its central pressure drop rapidly - this is called explosive cyclogenesis - or a weather bomb. In fact, Ciaran may break records for its low pressure centre.
