How does a hood scoop work?

This is for those of you who have a functional hood scoop...

What keeps water from getting sucked up into the carb? I understand the concept of drawing colder, denser air into the carb. But, if you are driving along at 65 mph in a downpour, wouldn't the rain blow right into the scoop and get sucked in through the air cleaner (especially an open-element breather)?

We're not sure of the hood clearance on Aaron's Duster, until we can get the 360 installed. If it is too tall (Mopar M1 intake, 1" spacer, Holley 4bbl, Mopar open-element breather), we will have to cut out the hood and install a scoop. Aaron's Dart Sport has the twin snorkel scoop, but it is just for appearance, not for function.
