While it’s true that San Francisco Bay Area weather is relatively dry, rains do visit despite months-long droughts. Just a few weeks ago, heavy rains showered South and East Bay cities, with Sunnyvale and Palo Alto among those experiencing thunderstorms. According to meteorologist Ryan Kittell, however, such a downpour would do very little to remedy water shortage.
Because the area receives too little amount of rainwater each year, some homeowners no longer bother installing gutters on their roof. However, knowing how much damage the “rare” rains can do may, perhaps, convince you to give your house the additional protection it needs.
