Northern California is being devasted by the unfortunately-named Camp Fire. The death toll is in the 70s'. Over a thousand people are missing, albeit with the possibility of several people being reported missing more than once. Paradise, California will never be what it used to be. It'd be lucky if 10% of the original population should decide to move back and rebuild their lives. The air quality is fluctuating between "very unhealthy" and "hazardous".
The thing you should donate is money. Google "camp fire where to donate". If you donate items, it burdens the community because then there has to be people to sort through it; with money, they can just buy what they need. Donations of blood don't travel very well, so if you live too far away, that won't help, either.
