Trump was upset about this and took to Twitter to insist he was right over the course of the week. To prove he wasn’t wrong, Trump on Wednesday released an image of a map showing the advancing storm, evidently doctored by hand with a marker, showing the hurricane heading Alabama’s way. When asked about the handwritten addition to the map, the president said he didn’t know who drew it, which The Atlantic called a “pointless lie” because it fooled no one, was already a moot point by the time the map was presented, and used a graphic about the storm produced three days before his warning about the alleged breaking news for Alabama.

Despite the pointlessness of this exercise, Trump continued to insist on his version of the truth on Friday, the same day the NOAA issued its statement, arguing that the “Fake News Media” went “Crazy” hoping he made a mistake.

Now, the NOAA is saying that the president’s forecast trumps scientists’ predictions, which means that not even weather reports during storms—a thing it seemed people of all political ideologies could agree upon as factual and valuable until now—can be trusted. Meteorologist and former NOAA COO David Titley called it “perhaps the darkest day” for the agency’s leadership on Twitter.

It’s a new low in politics and forecasting, and a sign that the greatest danger Americans currently face comes not from deadly hurricane winds but from blowhards in power.
