Cyclone Favio originated from a zone of disturbed weather that was first classified by the Météo-France office on Réunion (MFR) at 1200 UTC 11 February 2007.
[1][3] Midday on 12 February, the MFR upgraded the system into a tropical disturbance and noted that its rating at that time on the Dvorak technique was 2.0.
[4] Situated in an environment of low wind shear and good outflow, thunderstorm activity soon increased and thus started to consolidate around the storm's atmospheric circulation.
Continuing to encounter more favorable conditions, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on 14 February.
After intensifying slightly (based on JTWC data) that evening, the storm briefly weakened overnight, only to re-intensify the next morning.
[2] At 00:00 UTC on 19 February, the JTWC upgraded the system into a Category 1 hurricane-equivalent on the Saffir–Simpson hurricane wind scale (SSHWS)[3] though not much additional intensification was predicted.
[3] Several hours later, Favio was then upgraded into an intense tropical cyclone by MFR[2] as the system developed a very small eye.
During the afternoon hours of 20 February, the JTWC reported that Favio had developed winds equivalent to Category 4 intensity.
[10] Shortly after its peak, Cyclone Favio began to weaken;[3] the core of the storm started to become disrupted on the northwestern quadrant.
[2] Prior to the arrival of Favio, flooding swept over Mozambique weeks earlier, forcing 163,000 persons to seek shelter.
[28] While intensifying, Cyclone Favio brushed the southern tip of Madagascar while bringing heavy rains to the nation.
[33] Cyclone Favio destroyed 277,000 ha (684,480 acres) of crops, primarily in Vilanculos, Inhassoro, Govuro, and Masinga districts in Inhambane Province.
[33] The cyclone killed four people and injured at least 70 in the town, and thousands of homes were destroyed along with the hospital, where a total of 120 patients were evacuated.
[37] Elsewhere, the storm damaged trees and blew off rooftops in Pontagea, a highly populated suburb in the port city of Beira.
[1] Cyclone Favio was responsible for widespread damage in Tofo Beach, where the storm uprooted palm trees and destroyed electric services.
[31] In its formative stages, Favio dropped beneficial rainfall on Rodrigues island, reaching 217.6 mm (8.57 in) at Port Sud Est.
Throughout the country, damage was minimal and was mostly due to the uprooting of trees and not nearly as bad as Cyclone Leon–Eline, which devastated the nation seven years prior.
[40] Alongside moist air from the Intertropical Convergence Zone, Favio produced significant rains across much of Malawi, peaking at 121.7 mm (5 in) in Mimosa.
[41] During the aftermath of the storm, South Africa offered helicopters to Mozambique to deliver food to shelters and to help Mozambican officials assess the situation aerially.
[43] Due to the concern for potential disease epidemics including those of malaria and cholera, health officials raised public awareness through theaters and radio.
A joint coalition of the United States Agency for International Development and the Office of Foreign Disaster Assistance provided $626,500, enabling transportation of 50,000 mosquito nets to the devastated area.
Within 48 hours following Intense Tropical Cyclone Favio, roofs were being repaired, and power lines were gradually being restored.
[21][45] Key food items (rice, beans, corn meal, cooking oil, soap, and sugar) were distributed to the affected areas.
[46] On March 5, a plan was launched to provide victims for a total of $71 million worth of aid, of which $773,000 was expected to be directed towards the health.
[47] Moreover, a total of 28,000 lb (12,700 kg) of aid were distributed through the central part of the nation, and provided clean water for 6,000 people.
