Help! Loud sucking / blowing noise by font passenger tire

[ryanpw3]

Hi All,

I hope this is normal and I just haven't noticed it, but the last few days I have noticed a rather loud blowing noise while inside my car. Upon further inspection it is coming from the passenger side behind by front bumper. It is sucking air rather forcefully into the radiator on that side, and then appears to be blowing it back out through the vents in the wheel well, back into the front passenger tire.

My questions are:
1.) I have owned the car for about 11k miles (15k miles on it now), and have never noticed this until the last few days. I doubt I have missed it until now. What is it?
2.) Is it normal?
3.) If not, what can I do to get it fixed.

Thanks so much in advance for your advice!
