The storm also hammered the capital, Antananarivo, with high winds and flooding rain which caused numerous landslides.
As of Wednesday, Tropical Cyclone Giovanna turn into only a moderate tropical storm after plowing westward over the Madagascar and is now located over the Mozambique Channel.
Tropical cyclone Giovanna is now located 405 nm southwest from Antananarivo and is moving southwestward with speed of 12 knots according to latest Joint Typhoon Warning Center (JTWC) warning bulletin. Animated multispectral satellite imagery (MSI) reveals the low level circulation center (LLCC) became displaced from the deep convection while crossing Madagascar due to the lee-side jump phenomenon. Now that Giovanna is tracking over the open water of Mozambique channel, the tightly curved spiral banding is consolidating and the system is regenerating.
Given the enviromental conditions, the intensity is expected to steadily increase over the next 72 hours to a peak of 65 knots, after which system should weaken slowly according to JTWC.
