There are reports of dams bursting or of floodgates having to be opened, which is only going to exacerbate flooding. Also coz of the flat land, it takes longer for the water to recede i guess.

It's hard to find on the internet any of the things we take for granted like sat and radar images for Mozambique - so i guess they had very little warning

Other reports say the flood level in some parts was higher than electricity poles!

I don't know the details of the governments in the countries affected but i suspect they're plagued by corruption - that's not going to help when it comes to rescuing the 100 000 people in need of urgent help.
