The Atlantic - Not very common to see an ITCZ breakdown like this in the Atlantic. It happens due to Barotropic instability (essentially horizontal winds changing direction sharply over a small distance). This process sometimes sparks TCs in the East Pacific, but that usually has more moisture. https://t.co/KKOA0ROdwC
