Two things will help there:
1. Keeping it out, you can cover the hole at the front as long as you open up a similar sized hole at the rear of the hood on the underside opposite the other opening. Just make sure you don't limit your airflow with a smaller hole.
2. Get it out quicker, throw a scupper in there, I've got blowsions oneway in mine and it empties the hull in no time.
