Some warnings are circulating for fraudulent scams, malicious websites, email attachments and other attacks that can be disguised & taken advantage of if Hurricane Dorian impacts are experienced.  Well established charities like Red Cross or Salvation Army are often safer for example than a special new charity just established.

There are some important tips you should know before you donate to any charity that claims it will help people likely to be affected by Hurricane Dorian. The Federal Trade Commission says many scammers use natural disasters to take advantage of generous donors. Sometimes scammers will even set up fake charities to make a quick buck.  In order to figure out what is fake and what is real, the FTC said donors should always ask for detailed information about the charity, like its name, address and telephone number.  Government officials say donors should also be wary of charities that may be created within days of a disaster.
