WASHINGTON – President Donald Trump issued a warning for those in the potential path of Hurricane Dorian, which has strengthened to a Category 5 hurricane, on Sunday morning.

"BE CAREFUL! GOD BLESS EVERYONE!" wrote the president on Twitter, cautioning people in Florida, South Carolina, North Carolina, Georgia, and Alabama.

The hurricane's exact point of landfall on the East Coast is still uncertain, but the problem is, it appears that Trump was wrong about the pathway of the hurricane.

Shortly after Trump's tweet, the Birmingham, Ala., branch of the National Weather Service tweeted to clarify that Alabama was not in the pathway of Hurricane Dorian.

"Alabama will NOT see any impacts from #Dorian.," wrote the NWS. "We repeat, no impacts from Hurricane #Dorian will be felt across Alabama."

The president quizzed federal officials during a FEMA briefing later Sunday. He repeatedly expressed amazement that a storm could reach Category 5 status.

"Americans are strong, determined and resilient, and we will support each other. And we will work very hard to minimize whatever the effect of what's coming at us," Trump said during the briefing. "We don't know what's coming at us."
