Michael, which decreased to a tropical storm overnight, is  continuing to weaken  as it moves along the southeast U.S. coast.

There have been at least  two reported deaths  in the U.S. since Michael  made landfall  along the Florida Panhandle Wednesday afternoon as a Category 4 hurricane.  At the time, its maximum sustained wind speeds were measuring around 155 mph, making it the strongest hurricane on record to  directly hit that part  of The Sunshine State.

Michael was also the most powerful storm to make landfall in the continental U.S.  since 1992's Hurricane Andrew .

As of Thursday morning,  more than 500,000  customers still don't have their electricity restored across Georgia, Florida and Alabama.

And as the storm continues moving in a northeast direction,  forecasters predict  parts of Georgia, the Carolinas and Virginia could experience "life-threatening flash flooding." President Donald Trump told reporters he will most likely visit Florida  on Sunday or Monday  to meet with local officials and survey damage from the storm.

Prior to making landfall in the U.S., flooding from Michael had already led to  at least 13 deaths  in Nicaragua, Honduras and El Salvador.
