This infographic summarizes how many people are expected to travel to the path of totality and where they will congregate. The patterns of converging lines to the path of totality represent the quickest drive paths from throughout the nation to the path. These lines are color-coded by destination state. The blue circles in the path are destinations for eclipse travelers, proportionally sized to the expected traffic impact. The black dots are metropolitan areas throughout the country scaled to population.

This traffic shed diagram is interesting on so many levels. You can imagine what the congestion points might be on day of with an extra 2 million people trying to get around South Carolina.
It will also be interesting as the media starts ramping up as we get closer if more folks will decide to take this plunge, or figure that they'll be around in 7 years to catch the next one.
On Monday, August 21, 2017, a total solar eclipse will pass over the Pacific Northwest (Oregon, Idaho, Wyoming etc.). The California balancing authority area will be affected by a partial eclipse between 9:02 AM and 11:54 AM PPT. As a partial eclipse, the sun will be obscured from 76% in Northern California to 62% in Southern California border area. The reduction in solar radiation will directly affect the output of the photovoltaics (PV) generating facilities and rooftop solar.
From the California ISO 2017 Solar Eclipse Report.
In looking up 2017 Eclipse stuff, I wondered if anyone had modeled the Solar Power generation drops during it. Of course they had, and I quickly found this California ISO report on it. California will probably be hit harder than this than most given their solar install base, so accurate modeling is really important.
I have yet to find anyone modeling wind for the event. As that definitely does pick up with the temperature shifts pretty heavily right around the event. But maybe it's too little of an impact to notice?
