two FM stations at the same frequecy?

The reception of my favorite FM stations has markedly degrade
recently. I've been wondering why. Today, I realized one of
my two radio receivers was receiving a different FM station
at the same frequency while the other receiver was receiving
my favorite station. Both receptions were very bad (noisy).
Eventually, the second receiver switched back to my favorite
station and the receptions of both receivers improved.

This is the FM capture phenomenon. Whichever station is strongest
will "capture" the receiver.

I'm puzzled. First of all, is the bad reception of the original
station due to the second station? If so, is there something
I can do? such as complaining to some authority? I thought
the authority takes care of the allocation of radio frequencies
so that overlapping like this will never occur.

The allocation is selected so that it will seldom occur, but
atmospheric conditions change a lot from day to day.

Also, is there
a table showing which station has which frequency? I live
in Honolulu, Hawaii, USA.

Yes, there a search engine on fcc.gov somewhere. But if you tell
me what frequency you wre listening to, I could probably make a good
guess about what was going on. What was the weather like outside
when this happened?
