A week ago, there was a strong likelihood that a ‘tropical depression’ would create heavy rain in Salalah. Fortunately for Salalah, but tragically for Yemen , it veered away and the last few days was over southern Yemen. The video clip http://news.bbc.co.uk/2/hi/7689795.stm from Yemen shows a river pouring through “Al Ghar Al Amar” in the centre of Mukalla . The water catchment area in Mukalla is far smaller than that of Wadi Hadhramaut http://news.bbc.co.uk/2/hi/middle_east/7690463.stm or even I suspect Wadi Du’an; there the flooding might be horrific. Wadi Hadhramaut and its tributaries have extraordinarily sheer cliffs, carved by previous floods, which funnel the water in its restricted course . The article I wrote about Yemen finished …. ‘I was now left with one problem before I left, how to tackle the ascent out of the valley’ hopefully the inhabitants wont find they need an escape route.
