For me it is a "Seat of the pants" decision.. There are two reasons for this.
1: Different vehicles handle differently in high wind.. A storm that would blow the car I used to drive all over the road.. Would not even bother this motor home (As an example) does this make sense,, absolutely not, but that the way it was. The car I have now.. Never encountered such a storm when I was in the driver's seat so can not compare.. (only storm that bad I was in bed, jacks down, parking brake on, Plugged in, since I got this new towed).
Also 50 mph cross wind is bad. 100mph tail wind (I mean DEAD astern) is good.
(In fact such a "Breeze" pushed this rig to 13.8 MPG once)
So many factors need to be included in the decision.. Personally..... When the drive starts getting scary.... PARK ASAP!
