False-colored night-time satellite imagery from NASA-NOAA's Suomi NPP satellite clearly shows bands of thunderstorms wrapping into the eye of Cyclone Felleng as it parallels the coast of eastern Madagascar.

The Visible Radiometer Suite (VIIRS) aboard NASA-NOAA's Suomi NPP satellite captured a night-time image of Cyclone Felleng when it was located east of Madagascar (4:09 p.m. EST/Jan. 30 at 12:09 a.m. local time, Madagascar). The image was created at the University of Wisconsin-Madison and was false colored to reveal temperatures. The image shows powerful thunderstorms wrapping into the 20 nautical mile-wide (23 miles / 37 km) eye of the storm.

Felleng has intensified since Jan. 29 and as of 1500 UTC (10 a.m. EST) on Jan. 30, had near 115 knots (132.3 mph/213 kph). Felling is centered near 16.2 south and 52.6 east, about 400 nautical miles (460.3 miles/741 km) north-northwest of La Reunion Island. Felleng is moving to the southwest at 13 knots (15 mph/24 kph) and is a threat to both Madagascar and La Reunion. The storm is creating dangerous seas, with wave heights up to 38 feet (11.5 meters).

La Reunion has already issued a Yellow Alert. For updates (in French), visit:

Felleng is turning towards the south and continues to intensify. The Joint expects Felleng to pass between La Reunion and Madagascar.
