A low pressure trough moving slowly westward through the northwestern Hawaiian Islands caused destructive flooding and mudslides over the past weekend. The trough disrupted the normal northeast trade winds flow north of Oahu on April 12, 2018. This caused extremely heavy rainfall as the trough deepened and moved very slowly over Kauai during the weekend. The 28.1 inches (713 mm) of rain reported in Hanalei within a 24 hour period was close to a record for the small town on Kauai's northern coast. Almost 32.4 inches (822 mm) of rain was reported during the same period over Wainiha, Kauai
Precipitation Processing System (PPS) servers will be down for extended maintenance from Tuesday, September 22nd through Thursday September 24th. During this time the PPS websites, the PMM Publisher API, and the GPM research data server (arthurhou) will be unavailable. The GPM near real-time server (jsimpson) and satellite data collection will not be affected. Click here to learn more.
Winter rains falling on recently burned ground triggered deadly mudslides near Santa Barbara, California on the 9th of January. The potential for landslides is shown above. It was generated by the global Landslide Hazard Assessment for Situational Awareness (LHASA) model, a model that combines GPM precipitation data with a global landslide susceptibility map. LHASA gives a broad overview of landslide hazard in nearly real time, but site-specific information should be obtained prior to emergency operations or building projects. At least 15 residents of southern California have been killed by
More than 90 people have been reported killed and over 100 missing due to a landslide in the village of Bellana, in the Kalutara district of Sri Lanka. Heavy monsoon rainfall over the past few days caused the disaster. Heavy rainfall is shown over the southwestern Bay Of Bengal in this analysis of rainfall accumulation using NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data. This IMERG analysis included the period from May 23 to early May 26, 2017. The maximum IMERG rainfall accumulation estimates in this area were shown in the Bay Of Bengal to the northeast of Sri Lanka where
It is sunny in southern California today but recent unusually heavy rainfall led to rock slides, mudslides and flooding in that part of the country. Rainfall of almost 4 inches (101.6 mm) in one day was reported in Long Beach, California. Some highways in the area were flooded due to intense downpours. Rainfall since the fall of 2016 has improved drought conditions over northern California but Southern California has been slower to improve because of the exceptional rainfall deficit in that area. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the total
A storm does not have to be especially powerful in terms of its winds to be deadly. Such is the case with Tropical Cyclone 01B (TC 01B) in the Bay of Bengal. Despite only reaching minimal tropical storm intensity just this morning at 06 UTC 18 May 2016, the system has been responsible for dumping heavy rains in and around Sri Lanka and southern Indian over the past few days as it tried to organize itself in the southwestern Bay of Bengal. This set the stage for two massive landslides, which buried 3 villages in south central Sri Lanka. So far, although several hundred people have been rescued
Over the past week Japan has experienced extreme rainfall that resulted in flooding, landslides and many injuries. A nearly stationary front that was already moving over Japan caused much of the rain but tropical storm ETAU also interacted with the front and magnified the scale of the deluge. Heavy rainfall led to the evacuation of over one million people. This rainfall analysis from space was generated using NASA's Integrated Multi-satellite Retrievals for GPM (IMERG) data. It shows rainfall total estimates for Japan during the seven day period from September 2-9, 2015 when Japan was getting
