Excessive water in condensate pan

It is a hot day here in Washington. The homeowner has been cranking the AC. I am not used to seeing this much water in the condensate pan. Any thought to whats going on here? The condensate drain line goes out the side of the catch pan. The unit was in a mobile home manufactured in 1998.

Thank you.

I just realized the first picture needs to be rotated. I appologize.

Can’t tell much from photos, could be a clogged drain, could be restricted flow. Could be any number of issues. Report your find and recommend evaluation and repair by qualified licensed HVAC professional.

There was about 1/2 inch of water in the pan.
