Its easing off compared to the last few days but can still expect gusts to 60kph and all cross/tail out and head/cross coming back in.
My wheelsets are 24mm and 58mm and I'm 65kg and 179cm.
I have not ridden the 58's in wind that strong. First ride on them is was 20-30kph cross/head winds and you can notice it at the front. But no problem when you are alone. The races I've done on them have had bugger all wind.
I'm struggling for motivation to race in that wind, even on the 24's.
I dunno, where do you draw the line?

TT last weekend in very strong wind. 82mm front gave me a couple of moments at 60kmph speeds when hit by cross winds, but you also have a lot less control tucked down on the extenders. Rear disc was not an issue at all.
On the road bike I would ride an 80mm rear and a 50mm front in nearly any conditions... 90kgs, good skills & blunt rim profile.

So to answer your question I'd say around 50km/hr is where I'd consider swapping these wheels out. 78kg rider........

Lots of people were reporting that their deep wheels were very hard to control, with some good riders pulling out because of the danger. My old-shape Zipp 404s were feeling very flighty before the start and still have wobbles after repairs, so I switched to the 34mm semi-aero alloys which felt heavy and solid but even then I had to get off the aeros at one stage. Of course, the good guys seemed to handle deep rims and even discs with ease, although one current world record holder ended up losing a bit of bark.
Tip for young players - when you are riding close to giant wind farms in early spring, breeze is a distinct possibility!

up to 20km/h side wind could not touch me much, but on higher speeds at descents, sometimes you experience a burst of 45km/h wind (in some areas), that can seriously affect your safety if you do not expect it.
I have since downgraded to a 24mm rim still very light but super sturdy, but much less aero benefit,
however feel totally confident even at pushing for quickest descents with possible side wind.
