Help for family devastated by Maria

I'm reaching out to friends and family during this difficult time. As most people are aware, there have been many devastating natural disasters affecting the world recently. My family in Puerto Rico are among those affected.  Hurricane Maria hit Puerto Rico as a category five storm and caused major devastation. My sister, Blanca who lives in Guaynabo, my niece--who's in nursing school--in Toa Baja, and brother Jose with his children is Caguas, have all been majorly affected by the hurricane and its resulting storms and flooding. Guaynabo has been almost completely destroyed. My sister is almost out of food and has had to spend all of her savings to buy gasoline to power her generator, as the whole city is without. They don't know when/if they'll receive any help. We haven't even heard from my brother since the storm and can't verify his safety....which is worrying the rest of us in his family very very much... This hurricane has completely wiped out every single thing my family owns, flooded their homes, and they're in desperate need of support. I'm a single mother and can only help out so much financially so I'm asking if anyone can spare anything at all, it will go directly to helping my family survive and recover from this. I have so much gratitude to all of you who can help out.  Thank you.
