The weather can certainly be unpredictable. Just in March of this year, Californians got a surprise when a hailstorm pelted their beaches and turned them white. USA Today reported that the full inch of hail was from a fast-moving thunderstorm.
Hailstorms are quite rare in sunny California. After all, several cities in the state are in the top 10 list of having the all-time highest temperatures. Additionally, nine out of the 10 cities with the least weather variety are also in California. While hailstorms may be unusual, the heavy ones can do significant damage when they come.
