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

Intense rain storms have moved into Jeddah, Saudi Arabia today. Heavy downpours caused schools and universities to close. The General Authority of Meteorology and Environment Protection predicts that Heavy rain will continue for a couple days. NASA's GPM Core Observatory satellite measures precipitation from space with the first space-borne Ku/Ka-band Dual-frequency Precipitation Radar (DPR) and a multi-channel GPM Microwave Imager (GMI). The satellite passed over western Saudi Arabia on November 21, 2017 at 0123Z. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR)

Starting the week of November 20, PPS will generate and release Version 05B of the GPM IMERG Final products. The Version 05A GPM IMERG Final products with data dates between March and October 2014 products are valid HDF5 science products. However, these products yield errors when opened with NetCDF4 utilities and library. To satisfy the requirements of the NetCDF4 users, PPS will release Version 05B GPM IMERG Final products starting next week. All the contents, data format, data server address and documents are unchanged. If you are a HDF5 user, you can keep using these Version 05A products or

The GPM core observatory satellite provided information about rainfall associated with the remnants of tropical storm Haikui on November 2017 at 0929 UTC. Earlier this month, typhoon Damrey caused widespread destruction when it hit Vienam on November 4, 2017. Fortunately tropical storm Haikui dissipated over the South China Sea before it reached Vietnam. Rainfall data collected by GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments revealed that some storms with tropical storm Haikui's remnants contained light to moderate precipitation. A small cluster of

Starting on Monday November 13, 2017, PPS will generate Version 05 GPM IMERG Final products. The V05 IMERG Final products will be available both in STORM: https://storm.pps.eosdis.nasa.gov/storm/ and on "arthurhou": ftp://arthurhou.pps.eosdis.nasa.gov/ NASA requires that science users register at: https://registration.pps.eosdis.nasa.gov/registration/ to access PPS data services. PPS will reprocess the V05 IMERG Final products back to data date March 12, 2014. All users are encouraged to retrieve the V05 IMERG Final products to ensure that they use the most recent products. The V04 IMERG

Typhoon Damrey originated as a tropical depression over the Philippines on October 31, 2017. Damrey intensified while moving westward over the South China Sea and became a typhoon on November 3, 2017. Typhoon Damrey hit Vietnam's south central coast the next day with sustained winds of about 75 kts (~86 mph). Torrential rainfall led to deadly flooding. As much as 580 mm (22.8 inches) of rain was reported near the coast well north of where typhoon Damrey came ashore. The Vietnamese government reported that Damrey was responsible for 89 deaths. This rainfall accumulation analysis was derived

Tornadoes were reported yesterday evening in Illinois, Indiana and Ohio. At least nine twisters were reported between 1:40 PM EST and 6:22 EST (1840 - 2322 utc). This unsettled weather caused many customers to lose electric power in northern Ohio. One powerful storm injured eight people in the northern Ohio town of Celina. The severe weather may also be the cause of two deaths in Erie Pennsylvania. The GPM core observatory satellite had an exceptional view of the extreme weather in northeastern Ohio on Sunday November 5, 2017 at 6:12 PM EST ( 2312 UTC). The GPM satellite scanned tornado
