I imagine they'd rather film at times of the year when there's less likely to be 50MPH+ winds and/or heavy snow. Whilst I'm sure they have some contingencies as seen with this year's final being indoors, there's only so much that can be adapted or rescheduled.

High winds are never that long lived, it's the impact of them which is more of a problem - there's no guarantee that won't be a problem at any time of year tho. You'd just have more indoor challenges prepared I expect. Get a set of snow chains for the Jeeps and Bob's your Nigel ( ).

If it really was a dealbreaker you could just use one of the other international locations. Would still be cheaper than mounting a Survivor production.
