Hailstorms are prevalent across the United States, with "Hail Alley" (from southwest Texas to western South Dakota), the Great Plains, the Midwest, and the eastern coast experiencing the most activity. These regions face frequent and severe hailstorms due to factors like lower freezing altitudes and weather patterns, leading to significant damage and insurance claims. The western areas of states like Kansas and Arizona also report a high number of days with large hail during the summer. Thus, being prepared for hail is crucial in these areas.
