What could be termed the strongest storm of the winter has hit southern Britain with winds reaching 80 mph. The high winds battered Britain's southern coasts on Monday, uprooting trees, downing power lines and shutting several busy ports. Power companies indicated more than 11,000 people were without power across southwest England and Wales. Commuters struggled through the morning rush hour after gales roaring in from the Atlantic knocked down trees and damaged roofs. Heathrow Airport in London said 34 short-haul flights were canceled Monday morning because of the storm. Winds blew up to 60 mph in Belgium causing delays at Brussels airport and causing authorities to close roads.
