Tropical Cyclone Funani Develops Northeast of Mauritius

Tropical Cyclone Funani developed northeast of Mauritius on Tuesday.  At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Funani was located at latitude 15.8°S and longitude 64.0°E which put it about 505 miles (815 km) east-northeast of Port Louis, Mauritius and about 265 miles (425 km) north of Rodrigues.  Funani was moving toward the southwest at 5 m.p.h. (8 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 990 mb.

The circulation around Tropical Cyclone Funani organized quickly on Tuesday.  An inner rainband wrapped around the northern side of the center of circulation.  Bands of showers and thunderstorms developed and were revolving around the core of Funani.  There were more bands on the eastern side of the circulation.  Storms near the core began to generate upper level divergence which was pumping mass away from the tropical cyclone.  Winds to tropical storm force extended out about 120 miles (195 km) from the center of circulation.

Tropical Cyclone Funani will be moving through an environment favorable for intensification during the next several days.  Funani will be moving over water where the Sea Surface Temperature is near 29°C.  It will move under an area where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Funani could intensify into the equivalent of a hurricane/typhoon within 24 hours and it could strengthen into the equivalent of a major hurricane in about 48 hours.

Tropical Cyclone Funani will move near the southeastern end of a subtropical ridge.  The ridge and a trough over the southwestern Indian Ocean will steer Funani in a general south-southwesterly direction.  On its anticipated track Tropical Cyclone Funani will remain east of Mauritius and La Reunion.  Funani could be near Rodrigues in about 24 hours.  It could be the equivalent of a hurricane/typhoon at that time.

Elsewhere over the South Pacific Ocean, Tropical Cyclone 13S formed east of Madagascar.  At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 13S was located at latitude 12.3°S and longitude 53.6°E which put it about 570 miles (920 km) north of Port Louis, Mauritius.  It was moving toward the west-northwest at 10 m.p.h. (16 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 1002 mb.
