It's 5,000 miles long and it's coming for Florida

A giant seaweed bloom, visible from space, is heading toward Florida’s Gulf Coast and threatening to make it into a stinky, brown mess.

The 5,000-mile-wide sargassum bloom — believed to be the largest in history at twice the width of the continental US — is drifting ominously toward the Sunshine State, NBC News reported.

“It’s incredible,” Brian LaPointe, a research professor at Florida Atlantic University’s Harbor Branch Oceanographic Institute, told the news outlet.

“What we’re seeing in the satellite imagery does not bode well for a clean beach year,” he added.
