Brunswick

Warning Alert

Current
High

The Brunswick Warning Alert is a hybrid reactive bowling ball with the Alert core. RG 2.478 and differential 0.037 at 15 lb.

Following one of Brunswick’s most successful releases, the Warning Alert builds on the proven performance of the original Alert with a sharper, more dynamic motion. Featuring the trusted Alert core and wrapped in the same cover formulation as the Crown Victory, the Warning Alert is a hybrid engineered for medium-oil environments where added length and a more defined backend are critical. Compared to the original Alert, it pushes further down the lane before delivering a stronger move, while maintaining a more continuous motion than the black Danger Zone. The result is a versatile ball that excels during the transition and on higher-friction lanes, giving bowlers the motion they need to score.
