Giovanna

A weak tropical cyclone locally called Irina caused flooding over northern Madagascar less than two weeks after deadly flooding by Tropical Cyclone Giovanna . The lastest tropical cyclone didn't have very strong winds when it passed over the coastal city of Vohemar on Madagascar's northeastern coast but street flooding was reported. The rainfall analysis above was made at the Goddard Space Flight Center using data from a near-real time Multi-satellite Precipitation Analysis (TMPA). TRMM-based near-real time Multi-satellite Precipitation Analysis (TMPA) data are used to monitor rainfall over

The rainfall analysis above uses near-real-time, TRMM-based precipitation estimates (3B42)from a merger of all available satellite data. This Multi-satellite Precipitation Analysis (TMPA) done at the NASA Goddard Space Flight Center provides estimates of rainfall over the global Tropics. This rainfall analysis shows the rainfall from February 8-15, 2012 that was mainly caused by tropical cyclone Giovanna when it passed over Madagascar. This analysis indicates that the highest rainfall totals of over 250mm (~10 inches) fell in the coastal area east of Madagascar's capitol of Antananarivo. In

The TRMM Satellite had a fairly good early morning view of powerful tropical cyclone Giovanna approaching Madagascar on 13 February 2012 at 0333 UTC. Rainfall from TRMM Microwave Imager (TMI) data is shown overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) instrument. Giovanna was an intensifying category 4 tropical cyclone with with wind speeds estimated at over 125 kts (~144 mph) and is predicted by the JTWC to become slightly more powerful before hitting Madagascar.

Tropical cyclone Giovanna was located in the Indian Ocean east-northeast of Madagascar when it was classified as a tropical storm on 9 Febuary 2012. The TRMM satellite image above shows Giovanna when it was rapidly becoming more powerful on 11 February 2012 at 1200 UTC. Giovanna had intensified to a category 3 tropical cyclone on the Saffir-Simpson scale with wind speeds estimated at 100 kts (~115 mph). This TRMM pass shows that an eyewall replacement was occurring at that time. A small ring of strong convective storms was located around the center of the center eye and other powerful storms
