Tropical cyclone's continue to regularly develop in the eastern Pacific Ocean. Tropical Depression Fifteen-E formed in the eastern Pacific Ocean about 1000 nautical miles (1852 km) southwest of the Baja California peninsula early on Sunday August 26, 2018. TD15E became better organized with increased banding later in the day and was upgraded by the National Hurricane Center (NHC) to tropical storm MIRIAM. The GPM core observatory satellite saw the forming tropical storm earlier on August 26, 2018 at 0223 UTC. Heavy rainfall near the center of the forming tropical cyclone was examined with the

View Fullscreen in STORM Event Viewer Battling increased vertical shear, Hurricane Lane struggles northward, down from its Category 5 peak but still featuring winds of over 110 knots. The storm has already begun impacting the Hawaiian Islands, bringing over a foot of rain to Hilo via its outer bands. Lane is expected to continue northward, approaching the island chain, before slowly veering westward as it continues to lose strength. This weakening will not diminish its likely primary impacts, which will be intense coastal erosion and damage and torrential rainfall, upwards of 30 inches in some

For the period 03Z August 21 to 16Z August 22, the IMERG real time system experienced an outage of CPC 4-km IR data. Despite the outage, IMERG EARLY and LATE products continued to be produced but users should be aware that the quality of these products during this period may be suspect and should be used judiciously. Furthermore, the products for the first few hours after the outage are less than optimal due to IMERG restart but should be acceptable for most users. Detailed Impacts: (1) The precipitation propagation vectors for the period slowly degraded after 03Z August 21 due to the missing

The summer monsoon is a regular feature this time of year in India, and it can bring heavy rains to the region. However, periodically areas of low pressure can form within the general monsoon trough and bring even more rain. Although the extreme Himalayan topography located to the north is much more well-known, another contributing factor to the heavy rains along the southwest coast of India is the Western Ghats. Though much smaller than the Himalayas, this mountain range runs parallel to the West Coast of India with many peaks over 2,000 meters (~6,500 feet). As a result, the Western Ghats

View Fullscreen in STORM Event Viewer Direct strikes on Hawaii by tropical cyclones are relatively rare, but Hurricane Lane is poised to buck that trend if the models are to be believed. At the time of this overflight, Lane had maximum sustained winds of 130 knots and featured a symmetrical eye in the GMI data with intense precipitation rates on both east and west sides of the tight circulation. Its impacts are likely to start with flooding, especially on the island of Hawaii. High surf and strong winds will also have an impact, although the locations of maximum intensity will be determined by

It featured winds approaching 100 knots as it moved northwestward. Soulik is expected to recurve toward the western coast of Korea, where it is likely to have devastating impacts to the majority of the peninsula depending on its ability to maintain intensity.

The GPM core observatory satellite flew over hurricane LANE on August 21, 2018 at 7:48 PM PST (August 22, 2018 at 0548 UTC). At that time LANE was located about 316 nautical miles (585.2 km) from Hilo, Hawaii. Hurricane LANE is one of the strongest tropical cyclones to move into the Hawaiian Islands. At the time of this GPM pass LANE was a category five on the Saffir-Simpson hurricane wind scale with winds of about 140 kts (161 mph). This analysis shows precipitation derived from data collected by the GPM satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR)

L1C NPP ATMS intercalibration table has been updated to account for the NPP ATMS SDR calibration update occurred on March 8, 2017. As a result, PPS will change the L1C NPP ATMS product version to V05B. The downstream L2 - L3 product versions will also be advanced one letter from V05C to V05D.

Hurricane LANE had moved westward into the central Pacific Ocean far southeast of the Hawaiian islands when the GPM core observatory satellite passed above on August 19, 2018 at 1643 UTC. LANE had intensified and had maximum sustained winds reaching about 105 kts (~ 121 mph) at that time. This made it a category three on the Saffir-Simpson hurricane wind scale. The GPM satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments provided highly accurate information about precipitation within the hurricane. GPM's GMI revealed rainfall coverage and GPM's radar (DPR

View fullscreen in STORM Event Viewer Heavy rainfall and towering cloud heights were the findings when Hurricane Lane was scanned by the Global Precipitation Measurement mission or GPM core observatory satellite on Aug. 17. Lane strengthened to a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. GPM passed above Lane in the Eastern Pacific Ocean on Aug. 17, 2018, at 1:26 a.m. EDT (0526 UTC). Lane was intensifying and data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments revealed the location of its forming eye wall. Very heavy
