Well it got pretty exciting at about 3pm yesterday (22nd).
When the map updates this evening at around 8pm you'll see (assuming I put all the data in right...) that Mallachie continued SW in the morning till getting close to the coast of Senegal, and then turned S to follow the coast. At 2pm she was close to Kaboukoute in Senegal. She then continued S across the border into Guinea Bissau - coming to be within about 5km (or even less than that) to where Rothes was hanging around near Varela.
So that's pretty exciting... The data for Rothes has a gap between 12noon and 4pm for yesterday though (so potentially she had headed off out into the sea miles away from where Mallachie got to at 3pm - but I'm not planning on believing that - as she had been pretty settled the last while in the area near Varela).
Mallachie though didn't hang around in Guinea Bissau. Instead she headed E and slightly N back into Senegal, inland along the river. At 11am this morning (23rd) she was close to Badjikounda. Rothes stayed near Varela - the last point I have for her was 10am this morning.
I'll update again on Monday. Have a nice weekend.
