See this NPR story on the decision to end food and water distribution, FEMA To End Food And Water Aid For Puerto Rico.
For anyone without power and drinking water, they are definitely still in the response phase. It would seem more logical that those areas without power and water should receive special consideration for continued distribution of supplies.
Perhaps FEMA is saying that the mission is now for the Puerto Rico emergency management to accomplish. So be it — but imagine yourself being without commercial power or drinking water for five months. I'm surprised there isn't more outrage — but we who have had water and power for the last five months have moved on with our lives.
