Storm Dennis will be a menace for the UK

Storm Dennis is now taking shape in the Western Atlantic and will become more menacing over the next day.
A separate but powerful low-pressure system is already in the Atlantic, which will bring damaging winds and blowing snow to Iceland Friday.
Coastal areas of Iceland could see hurricane-force winds Friday, with gusts over 124 mph (200 kph) warned the Icelandic met office.
These two systems will dance around each other Friday before Dennis moves east.
Saturday, the most substantial portion of the storm should move to the north of Ireland and the UK on Sunday. Making this powerful storm appear weaker in the UK than Ciarra was last week.
