An Egyptian low

I am indebted to Helen Willets about news of a low pressure system that formed across Egypt yesterday and which is now running into the eastern Mediterranean sea, and which brought some unusual flooding to Cairo and surrounding areas. It’s not a great part of the world for SYNOP observations, but I notice that Cairo reported an 06-06 UTC total of 45 mm and Port Said 43 mm this morning.

It looks like NASA have been doing their own massaging of the more sensitive area of this mornings visible satellite image across the region. Notice the snow on the White mountains of Crete, and the orographic low (in the plotted chart) that’s formed off the south coast as a result of the northerly flow over the same mountains and known locally as the Boreas (Vorias) wind. The pressure from the airfield at Timbakion (#16759) at 12 UTC of 1002.6 hPa looks reasonable, unfortunately my contouring has handled it all wrong.

The image at the top of the blog is the goddess Tefnut portrayed as a woman, with the head of a lioness and a sun disc resting on her head, and is courtesy of Wikipedia. She was the ancient Egyptian goddess of rain which I thought quite fitting for an article about floods in Egypt.
