Joaquin, which became a tropical storm Monday evening (EDT) midway between the Bahamas and Bermuda, has now formed into a hurricane, the 3rd of the season--the difference is Joaqin could impact the US East Coast. GPM captured this image of Joaquin late yesterday afternoon at 21:39 UTC (5:39 pm EDT) on the 29th of September as Joaquin was moving very slowly towards the west-southwest about 400 miles east of the northwestern Bahamas.

Typhoon Dujuan formed in the western Pacific Ocean northwest of Guam on September 21, 2015. Dujuan intensified to a super typhoon with winds of 125 kts (144 mph) on September 27, 2015 as it approached Taiwan. The island of Taiwan experienced extreme rainfall and damaging winds with the passage of typhoon Dujuan. The typhoon also caused hundreds of injuries and at least three deaths in Taiwan. After pounding Taiwan the typhoon started weakening before hitting China. Dujuan dropped light to moderate rainfall over a large area of coastal China while dissipating.

Tropical Storm Joaquin became the 10th named storm of the season after forming late last night (EDT) in the western Atlantic midway between the Bahamas and Bermuda from what was previously a tropical depression (#11), which itself had formed a day earlier from an area of low pressure that had been lingering in the region since Saturday. GPM captured this image of Joaquin early this morning at 8:16 UTC (4:16 am EDT) on the 29th of September as the storm was slowly drifting westward about 390 miles east of the northern Bahamas.

Tropical Storm Marty, which formed into an depression from an area of low pressure about 300 miles southwest of Acapulco, Mexico Saturday afternoon (local time), has been trying to strengthen while drifting slowly northward toward the southwest coast of Mexico. This first image was captured by NASA's GPM core satellite at 00:11 UTC 27 September (7:11 pm CDT 26 September) just a few hours after Marty had formed into a tropical depression. GPM shows substantial areas of rain on the eastern half of the storm, but more importantly, there is already evidence of curvature and banding within those

The GPM core observatory satellite flew directly above newly formed tropical storm NIALA (06C) on September 25, 2015 at 1451 UTC (4:41 AM HST). Rainfall data were collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showing that intense storms just northeast of NIALA's center of circulation were dropping rain at a rate of over 126 mm (4.96 inches) per hour. Another rain band wrapping around NIALA's northeastern side was found to contain rain falling at a rate of over 56 mm (2.2 inches) per hour. 3-D radar reflectivity data collected by GPM's radar
