Here is a 90 hour PWAT forecast, through till Thursday.

The storm it shows is a monster sized cyclone - 700kms across - strengthened by warm waters and atmospheric water PWAT in very high quantities - due to all the recent convection in the area & continued flows from the NE.

This view shows the full water vapour transport picture over the coming 16 days from the GFS model. It indicates extreme rains over Zimbabwe and parts of South Africa.

And finally a rainfall solution forecast over 16 days - same GFS3 run. This shows a lot of rain in central and Southern Africa - indicating widespread flooding over very large areas.

P.S. To help viewing - here's a large static image of the 16 day total rain forecast wich shows significant (flood potential rainfall) over:

Madagascar
Mozambique
Zambia
Malawi
Angola
Namibia
& Botswana.

The model shows Freddy's remnantsl exiting over South Africa.
