November 3 is the 307th day of the year.
307, 63rd prime; Terrorism = 63
November 3 leaves 58-days left in the year.
Freemasonry = 58; Secret Society = 58; Rosicrucian = 58; *Washington = 58
November 3 can be expressed as 11/3, like 113. Scottish = 113
Keep in mind it is 2019. Seattle = 19; Chaos = 19 / 26 (11/3/2019 = 11+3+2+0+1+9 = 26)
While I'd say the rumors are possible, it wouldn't be the cataclysmic event that is being fear-mongered. Seattle has been built up by the tech companies and is a city of the future. If anything, they might attack the Pioneer Square District, but I suspect it will be an earthquake that knocks down that part of town, which is preserved as a historic district, but which many developers want to build skyscrapers in.
Keep in mind, November 3 is a Sunday, a date where the masses in the U.S. are distracted with football, just the way the powers that shouldn't be like it.
ALSO interesting, it is 68-weeks and 2-days after the release of the apocalyptic film, How It Ends, which finishes in Seattle, Washington.
