The fires may mean impacted shipping schedules for California so if you are shipping for the holidays you need to be mindful of deadlines this year. For UPS, the very last day to ship will be Friday, December 21st but that is for next day air (expensive). For the US postal service, you want to ship no later than Thursday, December 20th for first class (This includes holiday cards). Here is a handy cost/time calculator from UPS.
There are also several services you can sign up for to protect your identity and your packages. These services will track your packages, send notifications and schedule re-deliveries: USPS "informed delivery" will track your packages, Fed Ex "delivery manager", DHL "Pro view" and UPS "My Choice"
