Tropical Cyclone Eleanor formed over the South Indian Ocean north of Mauritius on Monday. At 1:00 p.m. EST on Monday the center of Tropical Cyclone Eleanor was located at latitude 14.1°S and longitude 56.6°E which put it about 415 miles (670 km) north of Port Louis, Mauritius. Eleanor was moving toward the east at 13 m.p.h. (21 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 999 mb.

A low pressure system over the South Indian Ocean north of Mauritius strengthened on Monday and Meteo France La Reunion designated the system as Tropical Cyclone Eleanor. More thunderstorms formed near the center of Eleanor’s circulation. Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Eleanor. Storms near the center of circulation 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 Eleanor’s circulation.

Tropical Cyclone Eleanor will move through an environment favorable for intensification during the next 36 hours. Eleanor will move over water where the Sea Surface Temperatures are near 29°C. It will move under the axis of an upper level ridge over the South Indian Ocean. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Tropical Cyclone Eleanor will intensify during the next 36 hours. Eleanor could intensify rapidly at times. Tropical Cyclone Eleanor is likely to strengthen to the equivalent of a hurricane/typhoon.

Tropical Cyclone Eleanor will move around the western end of a high pressure system over the South Indian Ocean. The high pressure system will steer Eleanor toward the south during the next 48 hours. On its anticipated track, the center of Tropical Cyclone Eleanor will approach Mauritius in 48 hours. Eleanor is likely to be the equivalent of a hurricane/typhoon when it approaches Mauritius.

Elsewhere over the South Indian Ocean, Tropical Cyclone Djoungou weakened rapidly west of Australia. At 4:00 p.m. EST on Monday the center of Tropical Cyclone Djoungou was located at latitude 30.7°S and longitude 93.9°E which put it about 1470 miles (2370 km) west of Perth, Australia. Djoungou was moving toward the southeast at 47 m.p.h. (76 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 984 mb.
