ST. LOUIS — St. Louis saw widespread rain after the remnants of Hurricane Helene on Tuesday. But what kind of rain did the storm bring?
Multiple accounts on Facebook claimed the storm system that drenched the region dropped saltwater rain due to how long Helene took to manifest. The accounts also claimed the rain, because of its supposed high acidity, the rain could potentially damage grass lawns and even car paint.
Is any of this claim true? We reached out to the area's top experts to VERIFY.
The question
Did Hurricane Helene's remnants drop saltwater rain on St. Louis?

The answer
No, saltwater rain didn't fall on St. Louis from Hurricane Helene's remnants.
What we found
The claim makes logical sense: Hurricanes manifest in the ocean, which is made up of salt water, and bring rain to the mainland.
5 On Your Side Meteorologist Jim Castillo, however, said with his degree in Atmospheric Science and being a Certified Broadcast Meteorologist with the American Meteorological Society, he has never heard of hurricanes producing saltwater rain.
"I lived and worked in deep south Texas with tropical systems in the South Padre Island TV market and I never heard of anyone having paint coming off cars due to rain with a higher content of salt water," Castillo said.
The reality is a bit more complicated than the Facebook posters would believe.
Hurricanes aren't formed by the gathering of ocean water. Instead, they're formed by water vapor that evaporates from the ocean.
"As the water evaporates from the ocean, it leaves behind all the salt," the National Weather Service St. Louis Office previously told 5 On Your Side when similar claims about Hurricane Beryl circulated. "Much of the rain that we experience through the year comes from systems that draw moisture from the Gulf of Mexico. If this claim was true, we would get salt water rain most of the year."
We can VERIFY: No, Hurricane Helene's remnants didn't drench St. Louis in saltwater.
