According to the National Weather Service , small hail and gusty winds remain possible through Wednesday evening in the San Francisco area, and residents could even see a few lightning strikes.
Major part of California impacted by thunder and hail. The warning is in place for the San Francisco Bay Area. What exactly should people in the Bay expect? Thunderstorms including hail, lightning, and strong winds could sweep the coast today, and the weather remains unpredictable.
Locals in San Fran urged to be careful amid wild weather conditions. The warning is in place until Wednesday evening, so residents should be mindful not to leave themselves in a vulnerable position until then, and if you’re outside make sure there is shelter nearby if the weather takes a turn. Why should people care? Thunderstorms bring dramatic weather conditions such as lightning and hail, and both of these things can pose a threat to life.
Lightning can set things alight when it strikes, causing fires, and hail can be deadly if big enough. Once hail reaches the size of 1 inch or larger it has the potential to cause damage to property, vehicles and people. How are hailstones created? Hailstones are created when raindrops are carried upward by thunderstorm updrafts into very cold areas of the atmosphere, causing them to freeze.
They then grow by colliding with liquid water drops that freeze on the hailstone's surface..
