Heavy rain hits the north county this afternoon.
For the past two days, fire officials have been talking to homeless people, telling them to stay out of the riverbed.
Stornetta said in the previous storm they rescued one homeless man from the riverbed twice.
If you need to protect your home from flooding, today is the time to do it. The heavy rain begins this afternoon, and will continue overnight and into tomorrow.
