The game was stopped just seconds into the second quarter as the officials pointed up toward the ceiling, noting condensation that was coming down onto the court. The Associated Press reports that the game, which was tied 29-29 at the time of the first leak, was delayed for 35 minutes before play continued.
Shortly after halftime, the game was delayed again for more than 20 minutes, as buckets were brought out onto the court to collect the pouring rain.
The AP provided additional details...
The leak was at center court near the scorer's table. Trash cans were placed on top of some towels to catch the water, and several people were in the rafters above the leak, apparently trying to fix the problem. Players from both teams took warm-up shots during the delays. Dwight Howard playfully blocked shots from a couple of young fans and signed an autograph.
Heavy rains fell in the region throughout the day.
Play resumed following the second delay and Houston wound up winning 114-107.
This isn't the first arena-related incident in the NBA this season. An October preseason game between the Bucks and Raptors at the Bradley Center was delayed because the court surface was too slippery. A December regular season game between the Spurs and Timberwolves held in Mexico City was cancelled and rescheduled because of smoke in the arena. Video via YouTube user ZombieProphet
