In better off countries like the Bahamas I would think twice about giving money in response to a natural disaster. Although the Red Cross movement is generally your best best in such countries, I *would not* suggest supporting the American Red Cross. The Bahamian Red Cross or perhaps the IFRC would be a better bet. Odds are though that the BRC has all the money it needs in the short term and although some funds will be needed in the longer term recovery they will probably put quite a bit into core funds.The text above is the meat of this Facebook post by Brendan Paddy.

Back in 2010 (Icons passim) when I was helping out with the Disasters Emergency Committee Haiti Appeal, Brendan was their Director of Communications. In short he knows his onions. I'm not qualified to have an opinion, but I will pass his on.
