The downpour began midway through the game. The rain swept through the area and obscured the view outside as it rolled down the glass panels of the roof.
The water seeped into a couple of concourses in the stadium and drainage issues caused flooding of three to four inches. The water stood for about 5 or 6 minutes, according to the Astros.
The public address announcer told fans during the seventh inning that the stadium would remain open after the game for those who wanted to wait out the weather. Only a handful of fans remained in the stadium an hour after the game.
There was an announcement around 6:45 p.m. that the weather had passed and people needed to leave the ballpark because the doors would close at 7 p.m.
