As expected, tropical storm Franklin intensified and was upgraded to hurricane Franklin in the afternoon of August 9, 2017. Franklin made landfall on the coast of eastern Mexico early this morning as a category 1 hurricane with winds of over 86 mph (75 kts). Heavy rainfall, flash floods and mudslides are expected as Franklin moves inland and weakens. The remnants of Franklin may survive the transit over Mexico's rough terrain and revive after moving into the eastern Pacific Ocean. The GPM core observatory satellite saw tropical storm Franklin with winds of about 69 mph (60 kts) as it was

The GPM core observatory satellite had an informative pass over Tropical storm Franklin on August 9, 2017 at 0302 UTC. The intensifying tropical storm had moved from Mexico's Yucatan Peninsula into the southwestern Gulf Of Mexico's Bay of Campeche. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data showed that Franklin contained a few heavy bands of convective rainfall. GPM's DPR found rain falling at a rate of over rain 2.4 inches (62 mm) per hour in bands of intense storms moving around the southwestern side of the storm. This 3-D view of tropical storm Franklin

The above window displays an interactive visualization of GPM data collected from Tropical Cyclone Donna on 5/7/17. Over the weekend tropical cyclone Donna dropped very heavy rain over Vanuatu as it moved toward the west of the islands. Donna had intensified and had maximum sustained winds of 115 kts (132 mph) on Monday morning. This made it the equivalent of a category four on the Saffir-Simpson hurricane wind scale. The GPM core observatory satellite had two excellent views of the intensifying tropical cyclone Donna on succeeding days. When GPM flew over Donna on May 6, 2017 at 0146 UTC the

Tropical cyclone Enawo has continued to intensify while moving toward Madagascar. Enawo had winds of about 90 kts (103.5 mph) when the GPM core observatory satellite flew over on March 6, 2017 at 0306 UTC (0606 AM local time). These powerful winds make Enawo the equivalent of a category two hurricane on the Saffir-Simpson Hurricane wind scale. GPM revealed that the tropical cyclone had heavy rainfall in distinct feeder bands on the western side and in the northeastern side of the eyewall. Precipitation was measured by GPM's DPR falling at a rate of over 220 mm (8.7 inches) per hour in intense
