In your climate, "the best time to prune is when your saw is sharp", as the saying goes. It's good to do reduction pruning before top heavy breakage and a wind event does it for you.
But another consideration is that plant metabolism slows down somewhat now until early spring, so growth response will be slower, therefore you may have to live with looking at the stubbed cuts for a longer period of time. If you wait for spring and the flush of growth that will occur right after pruning, you will get a more immediate response.
The rule of thumb for Best Management Practices is to prune no more than 25% of foliage from each plant in a one year period.
Water thoroughly before and after pruning if not during rainy season. Fertilizing will help stimulate new growth.
