We need more info to answer your question without needless  speculation.

What kind of windows do you have? If you have modern new windows, you may be
able to purchase a system directly from the manufacturer. At least Pella and
Anderson have a solution for some of their windows and skylights. If you
have heavy, old double-hung windows, the solution may be costly and not meet
your aesthetic criteria (read ugly).

Are you are handy with making and installing gadgets yourself? Do your own
home automation programming? Or you want a turn-key pre-built solution?

In general, one needs:

1) a way to mechanically close the windows (which depends on the type of
window),

2) a way to anticipate or sense rainfall (the details for an optimum system
depending in part on where you live) , and

3) a decision-making process which might be as simple as a relay connected
to  sensor or as complicated as computer with multiple inputs running custom
software or adapted/scripted home automation control program.
