Advice for high winds...

This is the best advice on here.
I run doubles up and down I-15 from L.A. and a 30 mph winds with 50mph+ gusts are normal in the winter. You cannot get caught by surprise and grab on and correct the wheel to hard.
A good example would be its windy and you get hit on the left side by a big gust and as soon as it goes away another big gust hits. If you are not prepared to steer into it a little and get complacent and you decide to yank the wheel because you were surprised its over.

Also coming down the I-15 To the I-10 west is a very tall overpass and when it is windy on your left side and you are curving left 150 feet in the air you better be slow and prepared. Trucks blow over on that interchange nearly every big wind event.

So I am not always loaded a lot of times empty pulling a set of doubles with 40+ mph winds and have never been blown over but I have seen some daylight under the wheels and the rear box is hanging out there pretty far. But I never get excited or caught by surprise and never make sharp steering input. And I still run pretty much the speed limit or better, I pass a lot of white knuckle wheel snappers.

In my opinion Sharp steering input with a high gust rolls over more trucks than the wind alone.
I mean I could roll a truck over in a parking lot at 30mph with a surprised hard yank.

 

best advice I can give other than parking for a while, try to change your route so as not to have the wind on your sides
