Which weather will remain if two Pokemon with weather-inducing abilities are sent out at the same time?

Question

Here's an example,

I lead off with Groudon with ability Drought and my opponent leads off with Kyogre with ability Drizzle, what will happen?

I do know that Kyogre and Groudon don't have Dream World abilities but still....

Answer 1

Whichever Pokemon comes out last will be the one to set the weather. For example, Groudon is sent out first by you and Drought activates, your opponent sends out Kyogre last thus activating Drizzle, which will be the weather that will be in battle bevause it was sent out last. Hope this helps.
