If you have'nt caught Groudon or Kyogre yet, the guy will tell
you that abnormal weather phenomena is happening on a certain
place, that's because Groudon/Kyogre is in the said area... But if
the guy is telling you that the weather is fine (fine is good),
then that means the abnormal weathers stopped already, that Groudon
and Kyogre has been captured or beaten...
