In the wake of hurricanes Helene and Milton, an outlandish conspiracy theory about the Federal Emergency Management Agency that has percolated for decades started to reappear online. Now, the government agency is making one of its strongest pushes against the claim to date.

Milton’s tornadoes were part of an unusual trend this year: Hurricanes in the U.S. have produced an abnormally high number of strong twisters.

Meteorologists calculate that more than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it. It’s an unheard-of amount of water that stunned experts.

The U.S. Southeast grappled Sunday with rising death tolls, a lack of vital supplies in isolated, flood-stricken areas and the widespread loss of homes and property while the devastating toll of Hurricane Helene became more clear and officials warned of a lengthy and difficult rebuild.

The storm, now a post-tropical cyclone, was expected to hover over the Tennessee Valley on Saturday and Sunday, the National Hurricane Center said.

Massive rains from powerful Hurricane Helene left people stranded, without shelter and awaiting rescue Saturday, as the cleanup began from a tempest that killed at least 58 people, caused widespread destruction across the U.S. Southeast and left millions without power.
