Though I'm still in Tel Aviv, I'm informed by friends that sirens continue to go off in Haifa. Avinoam reports that yesterday there were four sirens. I just spoke to my boss and she told me that today, although it's still morning, there have already been a bunch of sirens. The katyushot, however, have been causing minimal if any damage over these couple of days. Some seem to have landed in the sea.
If anyone in the north is looking for a free, safer place to stay further south, someone named Yaakova left a comment on Kishkushim that lodgings can be found on her blog, aliyahonmymind.blogspot.com.
