Many thanks to the southbound Speedbird who warned us about this whilst we were still in Algerian airspace (heading northbound). They went through the area at F310 and apparently had a very rough time. When we got there we were at F400 and it wasn't bad at all - a couple of minutes of "moderate", with speed excursions of +/- 10 knots - no sweat. Sometimes it pays to go high!!
