India's southwest monsoon (summer rainy season) normally occurs between June and September. This year's monsoon has been assessed as average but India's Meteorological Department statistics show that daily mean rainfall for the country has recently been above normal. At least 15 people were killed by floods and landslides in India on Wednesday July 11, 2018. So far this year, close to 200 deaths may have resulted from India's heavy monsoon rainfall. These estimates of rainfall accumulation were constructed using data from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG). Algorithms

After striking the Ryukyu Islands of Japan and grazing Taiwan with torrential rains, Typhoon Maria made landfall just north of the populous city of Fuzhou, China with sustained winds of 95 knots and a broad shield of precipitation. The storm appears lopsided in the GMI, with much of the deep convection offshore, however, it is still likely to bring a brief period of flooding rains to this part of China before dissipating.

On the morning of 7/9/18 the GPM Core Observatory satellite flew over powerful Typhoon Maria, observing a donut-shaped eyewall that is somewhat disconnected from the rest of the storm. Maria is likely to impact southern Ryukyu Islands before making landfall in Eastern China in the next couple days.

The image above shows estimates of accumulated rainfall using IMERG (Integrated Multi-satellitE Retrievals for GPM) data formed during the period from June 28-July 6, 2018. Typhoon PRAPIROON developed in the northwest pacific Ocean east-northeast of the Philippines on June 28, 2018. PRAPIROON became a typhoon on July 2nd as it approached the Korea Strait between Japan and Korea. Stormy weather had already produced heavy rainfall in Korea and Japan before typhoon PRAPIROON moved through the area. IMERG estimates indicated that PRAPIROON and other stormy weather dumped over 512 mm (20.2 inches)

Rapidly intensifying after its genesis near Guam, Super Typhoon Maria featured winds near 130 knots as it spiraled through the waters of the Western Pacific Ocean. The DPR scan indicates deep convection in several parts of the outer bands, with the most intense precipitation rates from GMI concentrated in the eyewall. Maria is expected to continue intensifying over the next three days, then weaken slightly as it crosses through the Ryukyu Islands, possible near Okinawa. The long range forecast has it making landfall in Northern China, possibly still as a

Fabio is expected to intensify over the next 24-48 hours, but will remain over open waters throughout its lifespan, eventually dissipating. Want to see other events in STORM Event Viewer?

NASA's GPM core observatory satellite flew above tropical storm FABIO in the eastern Pacific Ocean south of Mexico on June 30, 2018 at 10:46 PM MDT (July 1, 2018 at 0446 UTC). FABIO has continued to intensify since then and the National Hurricane Center (NHC) predicts that the tropical storm will become a hurricane later today. FABIO is then expected to become a major hurricane on July 3, 2018 and reach it's peak intensity with wind speeds of about 105 kts (121 mph). Rainfall measurements by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that FABIO

Tropical depression 09W was located in the northwest Pacific east of the Philippines when it was upgraded today to tropical storm PRAPIROON. The tropical storm is in a favorable environment for intensification. Vertical wind shear is low above the tropical cyclone and sea surface temperatures are warm below. NASA's GPM core observatory satellite had a good view of tropical storm PRAPIROON on June 29, 2018 at 0246 UTC. PRAPIROON was just barely a tropical storm with maximum sustained wind speeds estimated at about 35 kts (40.3 mph). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation

PPS is releasing version 3.80.44 build of the PPS TKIO toolkit using the 14.0.1 Fortran compiler for GPM. As detailed in our earlier announcement that you received on Thursday, June 28th, 2018, titled; "PPS is Reprocessing TRMM PR Data as TRMM GPM, Version 06A HDF5 products in Early July 2018" This is the version of the PPS I/O Toolkit that will be used for these radar products. The release notes are in this directory and are also attached to this Email: ftp://gpmweb2.pps.eosdis.nasa.gov/pub/PPStoolkit/GPM/tkio-3.80.44/ The tar file can be found at: ftp://gpmweb2.pps.eosdis.nasa.gov/pub

The TRMM Version 7 Precipitation Radar (PR) products will be superseded by new GPM era products with a reprocessing that will generate TRMM retrievals from the beginning of the TRMM mission to the end of data collection using a single frequency retrieval algorithm similar to that used for GPM Ku. This reprocessing will begin in early July, 2018. Retrievals previously available in the TRMM Version 7 products 2A21, 2A23, 2A25, and 3A25 will be available in the new 2APR and 3PR products. Note that these new GPM era products are in HDF5 format and similar in structure to those used for GPM DPR
