Hurricane Milton live updates: 16 killed, over 2 million without power in Florida

The IRS warned that criminals may try to take advantage of victims of hurricanes Helene and Milton, and the agency urged the public to be vigilant when donating to relief efforts.

"Our hearts go out to the victims of the recent hurricanes," the IRS Criminal Investigation service tweeted. "During times of crisis, many of us want to help—but unfortunately, scammers take advantage of these moments."

With six states from North Carolina to Florida under disaster declarations, the IRS is warning Americans to verify a charity’s legitimacy, be cautious of unsolicited texts and social media postings and to never send money in the form of gift cards, wire transfers or cryptocurrency.

"Be suspicious if they pressure you to act immediately," the IRS said.
