Hurricane Hilda Weakening, Heads Toward Hawaii

Three days ago Hilda was a category four hurricane on the Saffir-Simpson Hurricane Wind Scale with winds of 120 kts (138 mph). Hilda has been weakening and had winds of about 80 kts (92 mph) when the GPM core observatory satellite passed above on August 11, 2015 at 0411 UTC (August 10, 2015 at 6:11 PM HST). Rainfall data from GPM's Microwave Imager (GMI) instrument is shown overlaid on a 0400 UTC August 11, 2015 GOES-WEST Infrared image. GPM's GMI revealed that storms north of hurricane Hilda's eye were dropping rain at a rate of over 53.6 mm (2.2 inches) per hour. Hilda's future positions

Deadly Typhoon Soudelor's Rainfall Analyzed

Soudelor formed in the middle of the Pacific Ocean well east of Guam on July 20, 2015. Soudelor became more powerful with peak intensity of about 155 kts (178 mph) reached on August 3, 2015 when the super typhoon was well east of Taiwan over the open waters of the Pacific Ocean. Soudelor's winds died down a little but rebounded to with over 100 kts (115 mph) before hitting Taiwan . Although Soudler was still a powerful typhoon when it hit land most deaths and destruction were caused by flooding and mudslides from heavy rainfall not from strong winds. The rugged terrain over typhoon amplified

PPS Web Services Restored

PPS web services are now functioning normally. PPS has identified and fixed the previous production web server problem which caused the intermittent unavailability and/or slow response times experienced for the last few days.

GPM Sees Typhoon Soudelor On Taiwan's Doorstep

The GPM core observatory satellite continued to provide excellent coverage of Soudelor as the typhoon closed in on Taiwan. GPM flew directly above typhoon Soudelor's eye on August 7, 2015 at 1041Z (6:41 PM Local Time) when wind speeds were 110 kts (127 mph). Rainfall data from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments revealed very heavy rainfall in spiraling bands rotating around a decaying inner eye wall. Precipitation intensity can be measured by the Dual-Frequency Precipitation Radar instrument mounted on the GPM core observatory satellite. Some

PPS Web Services still Temporarily Slow or Intermittent

PPS web services are still experiencing intermittent unavailability and/or slow response times and our staff is working to resolve this problem as soon as possible.
