If met stats suggest, we are all to expect more weather related events like this in the future. I think the extreme weather events over the past few days do illustrate the need for all business to extend their contingency planning,
No its doesn't unless the economics support it. there is a common misnomer that becaise a bad thing happens very infrequently, that there must be a plan to tackle it.
If people are going to insist that prices are kept low instead of paying for contingency planning which goes unused apart from one week every five or so years, then it won't happen.
Sometimes you have to take it on the chin and live with it. Its why I never travel at peak holiday times which coincide with bad weather period - its just not worth it and personally I don't want to pay extra for my ticket at other times of the year.
