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.

On 1 December 2017 sometime between 07:00 UTC and 12:00 UTC, PPS will begin installing V05B algorithms for the near realtime (NRT) IMERG dataset. If no problems arise, the installation should take approximately 4 hours. During this period IMERG products will be unavailable. While this is the first V05 IMERG available from NRT, we are making the data product version V05B so that both the early and the late product will be consistent with the version of the final product which is at V05B. To avoid unnecessary emails, PPS will not send out an email when the V05 installation is complete. Users
