Tropical Cyclone Freddy Moves Toward Mozambique

Tropical Cyclone Freddy moved toward Mozambique on Wednesday morning. At 10:00 a.m. EST on Wednesday the center of Tropical Cyclone Freddy was located at latitude 20.8°S and longitude 40.0°E which put it about 260 miles (420 km) southeast of Quelimane, Mozambique. Freddy was moving toward the north-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (215 km/h). The minimum surface pressure was 959 mb.

Tropical Cyclone Freddy moved toward the coast of central Mozambique on Wednesday morning. Freddy appeared to be moving into a region of drier air. The ring of thunderstorms around the eye was broken and bands in the western half of Freddy’s circulation consisted primarily of showers and lower clouds. Most thunderstorms were occurring in the eastern half of Tropical Cyclone Freddy. Storms near the center of Freddy’s circulation continued to generate upper level divergence that pumped mass away from the tropical cyclone.

The circulation around Tropical Cyclone Freddy was small. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Freddy’s circulation. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Freddy was 19.2. The Hurricane Size Index (HSI) was 9.3 and the Hurricane Wind Intensity Size Index (HWISI) was 28.5. Tropical Cyclone Freddy was similar in size and intensity to Hurricane Zeta when Zeta hit Louisiana in 2020.

Tropical Cyclone Freddy will move through an environment that will be marginal for intensification during the next 24 hours. Freddy will be over water where the Sea Surface Temperatures are near 29˚C. It will be in an area where the upper level winds are weak and there will be little vertical wind shear. However, the drier air in the western half of Freddy’s circulation will inhibit intensification. Tropical Cyclone Freddy is likely to weaken gradually during the next 24 hours while it moves through the drier air. Freddy could strengthen again on Thursday if it moves into a more humid environment.

A high pressure system south of Madagascar will steer Tropical Cyclone Freddy toward the northwest during the next 48 hours. On its anticipated track Tropical Cyclone Freddy will approach the coast of Mozambique near Quelimane in 42 hours. Tropical Cyclone Freddy is likely to bring strong winds and locally heavy rain to the coast of central Mozambique. Heavy rain is likely to cause flash floods in some locations. Freddy could also produce a storm surge of up to 10 feet (3 meters) along portions of the coast.
