The Better Business Bureau is warning the public of hurricane donation scams amid the devastation of Hurricane Dorian.

The BBB recommends that you stick to experienced, reputable disaster relief charities if you want to donate your money to disaster victims.

Scammers are like vultures, so when there’s a disaster, they’re sure to be hiding around somewhere. As such, the BBB has several pieces of advice, starting with the fact that it’s safer to donate through experienced charities. A recent survey conducted by the BBB’s give.org revealed that 24% of individuals see appeals for charity for disaster relief as being “very clear.” This paints a bad picture for the state of charity in the US, but there are plenty of reputable and experienced organizations that’ll make sure money gets to those in need.

Among the warnings the BBB put out, they warn against supporting individual efforts to provide disaster relief. Some individuals will try to (or at least claim to) raise money to personally provide food, water, and other essentials to disaster victims. The problem is that there are several risks to your money if you support these individuals. Even if the individual is sincere and truly wants to help, their efforts can put their safety and the safety of others at risk. Furthermore, their efforts siphon off donations that could’ve otherwise been donated through charities that can organize professional disaster relief efforts.

To make the most out of your donations to disaster relief efforts, it’s best to go through reputable institutions. The BBB suggests that you look for the following before you make a donation:

1. Check the BBB’s give.org for free reports on charities and how they meet certain standards
2. See if the charity is present on the ground in the disaster area
3. Find out if the charity is providing direct aid or just raising money for other groups
4. Learn to understand crowdfunding more broadly so that you can make educated decisions when donating to disaster relief efforts
