as well as it is possible

"We ought to prepare ourselves as well as possible against a rainy day." There is no "it" involved.
A construction pattern with "it" included is:
It is advisable to prepare ourselves well against a rainy day.

Thanks, Vera.

But there is "it is" understood in the base sentence, right?

We ought to prepare ourselves as well as (it

Yes. "As well as it is possible to do so." When I said "there is no 'it' involved," I meant that there is no 'it' used. You picked that up beautifully.

Thanks, Vera.

Thus, what does "it" refer to in the base sentence if it's not omitted?

By the way, what do you mean by the bolded part? Is it "You learned that right?"

To do it--that is, to prepare ourselves.
