3:39 PM PT -- Ellen DeGeneres just posted an incredible video showing the true power of the storm and flooding. Ellen says her home is located on higher ground, so she's been ordered to shelter in place, however, you can see a creek on her property raging as she films next to it.
Prince Harry and Meghan Markle, Oprah, Ellen DeGeneres and everyone living in Montecito have been ordered to evacuate immediately, as a fierce winter storm has pounded the area ... and there is great cause for concern.
Montecito has been hit with more than 8 inches of rain in the last 12 hours, and more -- a lot more -- is on the way. Trees have toppled onto roadways, making it next to impossible to drive ... and that will clearly make the evacuation problematic.
This is also an ominous anniversary for Montecito ... five years ago today, 23 people were killed by a mudslide, that also destroyed more than 100 homes.
