Hurricane Joaquin as a Sign
R' Dov Bar Leib commented in a number of sites and also wrote a post on Mystical Paths about Hurricane Joaquin, which may very well hit the East Coast of the US, being named for King Yehoyachin. And he notes that if it hits the US, it will likely hit it on Hoshana Rabba.
Just to add in my two cents, I commented the following regarding King Yehoyachin:
He was exiled in the year 3327. That means that that was 2448+ years ago1. Perhaps, that's the idea behind the verse כימי צאתך מארץ מצרים אראנו נפלאות. What's the idea with "כימי"? Couldn't it just say כצאתך מארץ מצרים אראנו נפלאות? Perhaps, it's telling us the days from Creation to the Exodus are the days from Galut Yehoyachin until Mashiah.
1. According to Babylonian sources, the exile took place in the month of Adar.
