Heavy Weather (10) (ヘビー・ウェザー その⑩ Hebī Wezā Sono 10), originally Sunlight (太陽の光 Taiyō no Hikari) in the WSJ release, is the seven hundred twenty-eighth chapter of the JoJo's Bizarre Adventure manga. It is also the one hundred thirty-fourth chapter of Stone Ocean.
Meanwhile, as Weather's leg has been cut off and Anasui is transforming into snails, they are nearly helpless against Pucci who is mysteriously immune to the snail outbreak. Pucci declares himself victorious and turns his back to the duo, but Weather suddenly jumps to him, his right leg replaced with that of Diver Down. A close quarter fight ensues, but Weather Report is more powerful and its ability to manipulate gusts of winds violently propel Pucci toward a car. Weather closes in and uses a karate chop on Pucci, but the priest decides to reflect the sun's rays with a wing mirror. Anasui's transformation drastically accelerate, but Diver Down is disabled, crippling Weather again.
Pucci then exposes the power subliminal messages has on the human mind. Explaining that Heavy Weather modifies the atmosphere into influencing humans so that they believe they are transforming into snails, the human mind makes the transformation happen. However, since Heavy Weather is founded on sunlight, Pucci simply blinded himself, compensating with his mystic sense to detect Weather.
