Spend $20 and replace the belt (yourself) or spend $80 and have the
dealership do it. Do not spray any belt dressing on it because it's really
sticky and gets all over things and "gloms" up the engine compartment.

Belt. Definitely. Would bet $100 on it.

Re: Screeching sound from engine on 'cold' days
 

My power steering pump makes a whining sound when I start the engine on
real cold mornings (-10 F and below). That noise is different from a
slipping belt tough. The whine usually fades away within one or two
minutes. Seems that the PS fluid gets thick and the pump cavitates a bit.

Rubber and rubber-like compounds, unlike other materials, shrink when
they get hot. A cold belt warms up and shrinks.

Idler bearings usually get noisy when they get HOT, but a belt that
chirps cold is loose, or 'glazed' as someone else said it. Once the
engine is warmed up, squirt some water on one of the belts and restart.
If you get the same noise, that's the belt to tighten. You can also try
running the fan, headlights, stereo, portable beer fridge, to see if the
squeeling lasts longer. Then you could guess it's the alternator belt. I
think Honda belts have to be a lot tighter than they did on cars in the
'olden days'
