Tropical storm Tembin moved over the Philippine island of Mindanao on Friday December 22, 2017. Tembin added to the death and destruction already caused by tropical storm Kai-Tak that hit the central Philippines less than a week ago. Tembin brought heavy rainfall that resulted in more deadly flooding and landslides. At least eight deaths in the Philippines have been blamed on tropical storm Tembin. Rainfall totals in this accumulation analysis were updated to include IMERG data from both tropical storms Kai-Tak and Tembin. This rainfall analysis shows rainfall accumulation estimates from IMERG

Tropical storm KAI-TAK was nearly stationary at times as it drenched the Philippines during the past five days. The storm caused major flooding and landslides. Many homes, roads and bridges were reported destroyed by landslides. Over 30 deaths were caused by the slow-moving tropical storm. A rainfall accumulation analysis of tropical cyclone KAI-TAK was derived from NASA's Integrated Multi-satellitE Retrievals data (IMERG) for the period from December 13-18, 2017. Tropical cylone KAI-TAK's approximate locations and positions are shown overlaid in white on this analysis. IMERG data were used to

NASA's GPM Core Observatory satellite passed over western India on December 5, 2017 at 0521 UTC. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed precipitation from dissipating tropical cyclone OCKHI reaching India's western coast. GPM's radar (DPR Ku band) indicated that rain was falling at a rate of over 101.6 mm (4 inches) per hour in a few storms near India's coast. OCKHI's low level center of circulation, shown with a red tropical cyclone symbol, was located well to the southwest of the storms that were moving onto India's western coast. This 3

On December 2, 1027 OCKHI became the first tropical cyclone of the year to form in the Arabian Sea. Fortunately for India the tropical cyclone remained off India's southwestern coast. OCKHI intensified to the equivalent of a category 3 hurricane on the Saffir-Simpson hurricane wind scale before it started to weaken. Vertical wind shear caused OCKHI to weaken as the tropical cyclone started moving north-northeastward toward India's Gulf of Khambhat. NASA's GPM Core Observatory satellite passed over tropical cyclone OCKHI on December 4, 2017 at 0616 UTC. The rainfall coverage shown here was

Yesterday tropical Cyclone Dahlia became the first tropical cyclone of the 2017-2018 Southwest Indian Ocean season. Today, Dahlia was moving toward the southeast and was passing to the south of the Indonesian islands of Java and Sumatra with wind speeds of about 35 kts (40.3 mph). Tropical cyclone Dahlia was passing over the warm ocean waters (28-29 degrees Celsius) of the Indian Ocean. On November 29, 2017 at 1731 UTC NASA's GPM Core Observatory satellite passed above forming tropical cyclone Dahlia.
