It came out of nowhere.A storm the Strawhats had not raindrops,as large as a human head,Lightning lit up the sky,Thunder seemed to shake the earth.
Winds were the worst,they blew the Thousand Sunny around like it was a toy ship,playing with it and then,tragedy struck. A burst of wind hit the ship,causing it to spiral out of control,everyone holding on for dear life. Robin's grip had slipped,and she was tossed to stretched out his hand,caught her,but he lost his grip with the other arm,and both pirates were at the mercy of the wind.
Minutes later,it was was was only problem,Luffy and Robin were gone.
