Why has there been no abnormal weather in Pokemon Emerald?

If you want to collect Kyogre and gurrado after completing the alliance, you should first go to the weather center between 1 19 and 120. Ask the doctor, and he will tell you where the weather is abnormal. You can fly there, and when you find something unusual at the designated place, you can go back to the meteorological center. Maybe the location of abnormal weather will change, and repeat it several times until the location remains the same. If it's sunny, it's gurrado. Good luck. Roger that, beast
