Tropical Cyclone Ialy moved southeast of Kenya on Monday. At 11:00 a.m. EDT on Monday the center of Tropical Cyclone Ialy was located at latitude 5.5°S and longitude 43.7°E which put it about 235 miles (380 km) east-southeast of Mombasa, Kenya. Ialy was moving toward the northwest at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 994 mb.

Tropical Cyclone Ialy exhibited a more symmetrical structure on Monday morning. Showers and thunderstorms were occurring in all quadrants of Ialy’s circulation. Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Ialy. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. The removal of mass allowed the surface pressure to remain low.

Winds to tropical storm force extended out 100 miles (160 km) from the center of Tropical Cyclone Ialy.

Tropical Cyclone Ialy will move into an environment that will be more unfavorable for intensification during the next 24 hours. Ialy will move over water where the Sea Surface Temperatures are near 28°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. However, Tropical Cyclone Ialy is likely to start to pull drier air from east Africa toward its circulation. The drier air could start to inhibit formation of thunderstorms in the northern part of Ialy’s circulation. Tropical Cyclone Ialy is likely to weaken slowly during the next 24 hours.

Tropical Cyclone Ialy will move north of a high pressure system over the Southwest Indian Ocean. The high pressure system will steer Ialy toward the north-northwest during the next 24 hours. On its anticipated track, Tropical Cyclone Ialy will remain south of Kenya.
