Good morning, I'm Taylor Wilson, and this is five things you need to know Saturday the 19th of August, 2023.

Today, Hurricane Hillary approaches, plus how the biggest social media platforms are promoting anti-Semitic and hateful content.

And it's World Cup Final weekend.

Parts of Southern California were put under a tropical storm watch for the first time every yesterday, as Hurricane Hillary grew to a category 4 hurricane in the Pacific.

The storm will weaken as it approaches land, but it will likely hit the region as soon as tomorrow as a tropical storm with heavy rainfall and potential flooding expected.

Hillary was about 360 miles south-south west of Cabo San Lucas, Mexico yesterday with sustained winds of 145 miles an hour.

The hurricane center expects the storm to remain a hurricane as it approaches Mexico's Baja California Peninsula tonight before weakening to a tropical storm.

Hillary would become the first tropical storm to make landfall in California since 1939.

Meanwhile, there are worries that national parks in the Western U.S. could see severe flooding because of the storm, including Zion in Utah and Joshua Tree and Death Valley in California.

The world's biggest social media platforms are not just hosting anti-Semitic and hateful content, they're promoting it and making it easier to find.

That's according to a pair of new studies from the Anti-Defamation League and the Tech Transparency Project shared exclusively with USAToday.

I spoke with USAToday's senior reporter Jessica Gwynn to learn more.

Jessica, thanks for making the time.

Thanks so much for having me.

So you're right that there are new studies out on social media and hate content. What are the studies and what were the big reveals here?

Well, Will Carlis and I teamed up to write about two new studies that show that social media platforms like Facebook, Instagram and X, otherwise known as Twitter, are recommending anti-Semitic content and making it easier to find.

In one of the studies researchers created six online accounts for fictional people, four adults and two teenagers.

They had the accounts follow some anti-Semitic folks and then just some popular stuff that's not in any way connected to extremism.

And the study found that these platforms began pushing pretty hateful suggestions and the more the accounts liked pages or followed other accounts, the more anti-Semitic content they were shown.

It's not really news that social media platforms are right with hateful content, but the proactive way these platforms were serving up this content is really troubling at a time when we have a historic surge in anti-Semitic incidents in this country.

And at a time when the number of Americans who believe in anti-Semitic tropes has doubled since 2019.
