Tropical Cyclone Freddy Rapidly Intensifies to Equivalent of Hurricane/Typhoon

Tropical Cyclone Freddy rapidly intensified to the equivalent of a hurricane/typhoon over the Mozambique Channel west of Madagascar on Tuesday morning. At 10:00 a.m. EST on Tuesday the center of Tropical Cyclone Freddy was located at latitude 22.8°S and longitude 42.0°E which put it about 110 miles (185 km) west-northwest of Toliara, Madagascar. Freddy was moving toward the northwest at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h). The minimum surface pressure was 969 mb.

Tropical Cyclone Freddy rapidly intensified to the equivalent of a hurricane/typhoon west of Madagascar on Tuesday morning. A small circular eye with a diameter of 15 miles (24 km) formed at the center of Freddy’s circulation. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Tropical Storm Freddy. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone.

The circulation around Tropical Cyclone Freddy became more symmetrical when Freddy intensified rapidly. Winds to hurricane/typhoon force extended out 35 miles (55 km) from the center of Freddy’s circulation. Winds to tropical storm force extended out 140 miles (225 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Freddy was 16.5. The Hurricane Size Index (HSI) was 11.8 and the Hurricane Wind Intensity Size Index (HWISI) was 28.3.

Tropical Cyclone Freddy will move through an environment favorable for intensification during the next 36 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. Tropical Cyclone Freddy will intensify during the next 36 hours. Freddy is likely to strengthen to the equivalent of a major hurricane within 36 hours.

A high pressure system south of Madagascar will steer Tropical Cyclone Freddy toward the northwest during the next several days. On its anticipated track Tropical Cyclone Freddy will gradually move farther away from Madagascar. Freddy will approach the coast of Mozambique near Pebane by the end of the week. Tropical Cyclone Freddy is likely to be the equivalent of a major hurricane when it approaches Mozambique.
