San Francisco has two seasons: rainy season and foggy season. The former is late fall, winter, and early spring. We're coming up on June so it's very rare for us to get any more rain. The homeless vomit and excrement on the streets today will just sit there--unmolested--until the first rain six months from now.
Today there is a chance of showers. I will carry my umbrella around like a d*uchebag all day. Therefore, it won't rain. The people of San Francisco should thank me.
