Hurricane Douglas continued to approach the Hawaiian islands during this GPM overpass early in the morning (02:11 UTC) of July 25, 2020. Douglas had previously strengthened to a Category 4 hurricane the day before, but had substantially weakened over cooler waters throughout the day. Regardless, the GMI and DPR instruments recorded rain rates near 50 millimeters/hour (~2 inches/hour) near Douglas` center. The Central Pacific Hurricane Center advised residents of Hawaii to expect hurricane-strength winds and rainfall starting Saturday evening and lasting through Monday. View fullscreen in STORM

From July 3-9, 2020, NASA’s IMERG algorithm continued to observe the heavy precipitation that fell as part of the seasonal Meiyu-Baiu rains (“plum rains”) in east Asia. Weekly totals reached their regional maxima over the island of Kyushu in southern Japan. About half of the island of Kyushu received over 45 cm (~18 inches) of rain. The majority of Honshu, Japan’s main island, as well as Shikoku to its south, were also impacted by the rains, receiving from 10-25 cm, depending on the location. Additionally, large areas of eastern China were also covered by the plum rains during this weekly

The National Aeronautics and Space Administration (NASA), Science Mission Directorate, Earth Science Division has selected new projects from the 2018 Precipitation Measurement Missions (PMM) Science Team focus area solicitation. PMM projects focus on investigations related to satellite observations of precipitation using measurements from, but not limited to, the Global Precipitation Measurement (GPM) Core Observatory, GPM mission constellation partner spacecraft, and the Tropical Rainfall Measuring Mission (TRMM). Specifically the PMM program supports three types of investigations: (1) The

This animation shows NASA IMERG rain rates (blue shading) and accumulations (green shading) near Kyushu island, in the southwest of Japan from June 29 - July 5, 2020. Devastating floods and landslides swept through parts of Kyushu on July 4, 2020, resulting in over 40 deaths and orders for hundreds of thousands of people to evacuate their homes according to media reports.
