Tropical Cyclone Guambe intensified east of Mozambique on Thursday. At 7:00 p.m. EST on Thursday the center of Tropical Cyclone Guambe was located at latitude 24.2°S and longitude 37.3°E which put it about 130 miles (210 km) east of Inhambane, Mozambique. Guambe was moving toward the south at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 70 m.p.h. (120 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 976 mb.
Tropical Cyclone Guambe intensified to nearly the equivalent of a hurricane/typhoon over the Mozambique Channel on Thursday night. A small circular eye at the center of Guambe was evident on microwave satellite images. 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 Cyclone Guambe. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation.
Tropical Cyclone Guambe will move into an environment that will be favorable for intensification during the next 24 hours. Guambe will move over water where the Sea Surface Temperature is near 29°C. It will move under the center of an upper level ridge. The winds are weak near the center of the ridge and there will be little vertical wind shear. Tropical Cyclone Guambe will strengthen into the equivalent of a hurricane/typhoon during the next 6 hours. Guambe could intensify rapidly for a period of time and it could strengthen into the equivalent of a major hurricane during the next 36 hours.
Tropical Cyclone Guambe will move around the western side of a subtropical high pressure system over the South Indian Ocean. The high will steer Guambe slowly toward the south during the next 36 hours. On its anticipated track Tropical Cyclone Guambe will move parallel to the coast of Mozambique. Rainbands on the western side of Guambe could bring gusty winds and heavy rain to the coast of southern Mozambique.
