NASA-NOAA’s Suomi NPP satellite passed over Tropical Cyclone Ava as it made landfall along the coast of northeastern Madagascar.
On Jan. 5 at 5:24 a.m. EST (1024 UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite showed the eye of Ava over the northeastern coast near Mahavelona. Mahavelona is a town located in the district of Toamasina II, in the region of Atsinanana. The eye is about 10 nautical miles wide on satellite imagery.
NASA's Terra satellite passed over the Northwestern Pacific Ocean and found newly formed Tropical Storm Tembin in the Philippine Sea as it was nearing the southeastern Philippines.
On Nov. 29 Tropical Cyclone Dahlia became the first tropical cyclone of the 2017-2018 Southwest Indian Ocean season. The Global Precipitation Measurement Mission or GPM core satellite provided forecasters with a look inside the clouds and into the rate rain was falling. Heavy rainfall has created the potential for landslides and NASA analyzed areas that may be subject.
When NASA's Aqua satellite passed over Tropical Storm Ockhi, it measured cloud top temperatures that showed strongest storms were off the coast of southwestern India. Infrared data showed Ockhi intensifing into a typhoon.
The Atmospheric Infrared Sounder aboard NASA's Aqua satellite captured an infrared image of Ockhi on Nov. 30 at 3:17 p.m. EST (20:17 UTC) and showed coldest cloud tops and strongest storms were just off the southwestern coast of India.
