Associated deep convective activity remains very scattered from
equator to 20S and is locally strong.
This zonal ITCZ is expected to keep on existing within the next few
days between 10S and 15S and the upper level ridge is expected to
progressivily install along 20S.
This forecast dephasing between low and high levels should generate
moderate to strong easterly vertical windshear over ITCZ ,
unfavourable for cyclogenesis at short or medium range.
Deep convective activity along eastern Malagasy coastline is
sustained by the left exit of the upper level Jet under a good

The remnants of the ex tropical low nr4 is now extratropical and is

It would take away the low level convergence axed along 55E in the
