Hurricane Hilary is inching up the Baja Peninsula on its way toward San Diego and portions of Southern California. On Friday, August 18, the National Hurricane Center issued its first-ever Tropical Storm Watch for Southern California.

Sunday will bring stronger bands of showers and in some cases severe thunderstorms, capable of producing strong downdrafts of wind and downbursts of rain.
