Tropical Cyclone Anais, the first
tropical cyclone of the Southern Indian Ocean’s tropical cyclone season,
has strengthened over the weekend of Oct. 13 and 14 and by Oct. 15, the
storm was packing sustained winds near 100 knots (115 mph/185 kph).
The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument
aboard NASA’s Aqua satellite captured a visible image of Tropical
Cyclone Anais off Madagascar on Oct. 15 at 0940 UTC (5:40 a.m. EDT) and
revealed an eye. Multi-spectral satellite imagery showed that convection
has continued to decrease around Anais’ ragged eye, indicating that the
storm may be weakening.
On Oct. 15 at 1500 UTC (11 a.m. EDT) Anais was 650 nautical miles
(748 miles/1,024 km) northeast of La Reunion, and has been moving to the
southwest at 8 knots (9.2 mph/14.8 kph).
Over the next several days, Anais is forecast to move past La Reunion
Island, while the center of the storm stays to the north and west of
the island. As the storm moves further southward, it will move into
waters below the 80 degree Fahrenheit (26.6 Celsius) threshold needed to
maintain the system. In addition to the cooler waters wind shear is
forecast to increase, so Anais is expected to weaken over the next
several days.
