Organisers last weekend and this weekend were/are faced with the difficult decision on whether, and when, to cancel events. A decision might be made for them, by landowners, but if it isn't what do we expect?
If the bad weather is wind alone, in an open area, is it something like:
Force 9+ (47mph+): expect cancellation
Force 8 (39-46mph): variable
Force -7 (-38mph): no problem
Perhaps adjust by 1 scale if in a forest (tree risk), or if accompanied by heavy rain? I.e. cancel at 8+ ?
Of course it also affects travel to/from the event, and planners/controllers putting out controls say 24 hours earlier.
And when do people want to be told? 48 hours before? 24 hours before? At 06:00 on the morning of the event? Early cancellation might mean the event could have gone ahead if the weather improves. But it could also help the organising club if traders, first aid, toilet suppliers etc can be cancelled with little or no cost.

Re: Weather cancellations
I've always wondered whether some form of orienteering-specific weather forecast might be of use to clubs/organisers, both in terms of hazards (wind, rain, temperature, snow etc) reaching certain thresholds or longer term (a week or two) 'heads-up' outlooks.
I'm a professional forecaster with a whole suite of data available to me through work and several years experience of forecasting and orienteering. I thought about it a couple of years ago, so made a mock-up of what such a forecast might look like and what kind of thresholds might require cancellation or at least some alternative plans to be made at an event.
If anyone wants any weather-related advice or is interested, please drop me a message!

Interesting idea. Quite often the decision is taken by the landowner. For example, Forest England have cancelled all activities in Thetford Forest this weekend.

Re: Weather cancellations
It’s obviously not quite as simple, but as a yardstick I thought Yellow warning = Go ahead, Amber warning = Cancel might be good?
On the other hand, if there’s heavy wind and rain forecast is it really worth the trouble of going ahead with what are ultimately just “for fun” events without any championship status?
Fingers crossed for the British Nights next weekend, I’m guessing they wouldn’t be happening if they were this Saturday..

Re: Weather cancellations
There are some venues that would survive even an amber warning.

Re: Weather cancellations
At least you're not having to cancel events because of extreme fire risk and/or excessive smoke pollution from existing fires.
