Day 1 of 180?

Tonight the wind is fierce. It started early evening and has not stopped since. I'm told that the 180 days of wind that Herat experiences each year is just like this. There were dust clouds rolling over and through the camp. I've discovered that in addition to leaking water when it rains, my windows and door allow some of the wind to slip in. My curtains have been fluttering, not much but enough to know that it could be a lot worse at higher wind speeds. I can't help but wonder, is tonight the beginning of the 180 days of wind?
