Re: ITCZ ? Movement and is it moving north now?

These links are to 5 Day Hovmoller diagrams for the Tropical Atlantic.
They are basically strips of satellite photos along the respective areas. A 5 day freeze frame.
As Clark said there isn't a lot of amplitude in the ITCZ right now. Using these diagrams you can visualize the day-to-day movement of each area.
You could print a page of each one to see the movement.
