The Rain and the Wind

We've had lots of opportunity to be weather watchers this month! I've noticed that the first sign of an approaching storm is often a change in the wind. Our usual afternoon wind at school is a north or west wind that blows up the Valley from the ocean. But before and during a storm the wind usually blows down the Valley from the south or east. Just look how many of the hundreds of downed trees lie pointing northwest. Our winter storms come from the north, even with El Niño. So why do the wind and rain come from the south?

Note: Our part of Central California has been slammed by one storm after another this month. We had two feet of rain in one week at my house in the mountains behind Santa Barbara! This stumper is about our storms, but I think an East Coast nor'easter raises the same question: the storm moves up the Atlantic coast from the south, but the wind and rain come off the ocean from the northeast. Why?
