All moms in HK,
There's no typhoon in SF. But, the weather change can be great in a day, cold and misty in the morning, hot and sunny at noon, then cold and foggy again at night. Also, we have earthquake here. Some weeks ago, I felt one at night time. My whole bed shaked for 5 seconds and my hubby told me it's earthquake. It there's a real big earthquake, the situation can be very bad.
