Sounds like the fan clutch engaging because the engine temp is up due to
the AC condenser dumping all that heat through the radiator. This
happens to me occasionally if I'm sitting in traffic - I go to give gas
to accelerate and ROOOAARRR! The fan usually quiets down after I get
moving and the engine cools down a bit.
If your fan is still making the roaring sound - ie. it never seems to
return to normal, the fan clutch may be stuck engaged. The fan should be
able to spin freely with the engine off.
