Intensifying Tropical Storm Nock-ten Heads Toward Philippines

Heavy precipitation and strong winds from typhoon Nock-ten are expected over the Philippines for several days as the country is celebrating the Christmas holiday. Tropical storm Nock-ten is predicted by the Joint Typhoon Warning Center (JTWC) to strengthen into a powerful typhoon with winds of about 105 kts (121 mph) before it reaches the Philippines. Nock-ten is predicted to weaken after hitting the eastern Philippines but still have winds of over 80 kts (92 mph) as it travels close to Manila, the country's capital. The GPM core observatory satellite had a good view of Nock-ten when it passed

Tropical Storm Otto Develops, Threatens Central America

Tropical storm Otto formed in the southwestern Caribbean north of Panama on November 21, 2016. The GPM core observatory satellite had an excellent daytime view of the newly formed tropical storm on November 21, 2016 at 1906 UTC (2:06 PM EST). Otto had wind speeds estimated at 45 kts (52 mph) at that time. GPM satellite rainfall data are shown overlaid on a visible and infrared image captured by the GOES-EAST satellite at 1915 UTC (2:15 PM EST). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) revealed that the newly formed tropical storm had deep convective bursts in

GPM Finds Intense Rainfall In Matthew Rainband

Matthew rapidly intensified Thursday evening and winds increased to 100 kts (115 mph) by Friday September 30, 2016. The GPM core observatory satellite flew over Hurricane Matthew on September 20, 2016 at 0946Z (5:46 AM EDT). A rainfall analysis from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) showed that the Matthew had heavy rainfall in the northern side of the newly formed eye wall. GPM’s radar area of coverage (shown in a higher shade) included a very intense feeder band on the southeastern side of the hurricane. DPR measured rain falling at a rate of greater

Tropical Storm Matthew Forms Over the Windward Isles, Enters the Caribbean

A fairly strong tropical wave that had been making its way westward across the Central Atlantic over the past several days has now finally organized itself into a tropical storm, Tropical Storm Matthew, the 13th named storm of the season, while passing through the Windward Islands. The storm is poised to intensify as it enters the eastern Caribbean. The tropical wave leading to Matthew's formation emerged off of the coast of Africa back on the 23rd of September. However, despite having a robust level of convective thunderstorm activity, the wave did not acquire a closed low-level circulation

GPM Finds Heavy Rain In Tropical Storm Ulika

The GPM core observatory satellite had a good early morning look at newly formed tropical storm Ulika on September 27, 2016 at 5:26 AM HST (1526 UTC). Ulika was located in the central Pacific Ocean less than 975 nautical miles east-southeast of Hilo, Hawaii. GPM found that Ulika contained some very powerful convective storms and a well defined center of circulation. GPM's Dual-Frequency Precipitation Radar (DPR) discovered that some strong convective storms inside the tropical storm were dropping precipitation at a rate of over 187 mm (7.4 inches) per hour. A GPM radar slice through the center

Remnants Of Post Tropical Storm Julia Checked By GPM

The National Hurricane Center (NHC) issued the last advisory on post tropical storm Julia on September 19, 2016 but the remnants have persisted off the Southeast coast. The remnants of the low are interacting with a slow moving frontal system and are now dropping rain over eastern North Carolina and Virginia. The GPM core observatory satellite flew over this area on Tuesday September 20, 2016 at 7:31 PM EDT (2331 UTC). The satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed the location and intensity of heavy rainfall within this area of low

GPM Observes Weakening Tropical Storm Julia

Tropical storm Julia was recently downgraded to a tropical depression. The GPM core observatory satellite had an excellent view of tropical storm Julia on September 14, 2016 at 9:36 PM EDT ( September 15, 2016 0136 UTC). Julia was barely a tropical storm at that time with maximum sustained winds of about 40 mph ( 35 kts). Over the past few days Julia has dropped heavy rain along the Atlantic coastline from northeastern Florida to North Carolina. Some areas have received over 8 inches (203 inches) during the past few days. The GPM satellite measured Julia's rainfall and found that intense

GPM Sees Increasingly Organized Tropical Storm Hermine

Tropical Depression Nine was upgraded to Tropical Storm Hermine on Wednesday August 31, 2016 at 2 PM EDT (1800 UTC). The GPM core observatory satellite passed directly above newly designated tropical storm Hermine on August 31, 2016 at 4:06 PM EDT (20:06 UTC). Rainfall data derived from GPM's Microwave (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that precipitation intensity had increased and moved into western Florida. Rainfall measured by GPM's DPR had increased to a rate of over 9.9 inches (251 mm) per hour in very powerful storms in the Gulf Of Mexico northwest of

GPM Examines Tropical Storm Lester

Lester became the 12rd named storm of the 2016 eastern Pacific Ocean hurricane today. Lester was far away from the Mexican coast early today and headed toward the west-northwest. Low vertical wind shear and warm sea surface temperatures are expected to assist Lester's intensification to hurricane status tomorrow. Tropical storm Lester had wind speeds of about 35 kts (40 mph) when the GPM core observatory satellite passed over on August 25, 2016 at 1026 UTC. Data from GPM satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that Lester was getting

Gaston Hovers Around Hurricane Intensity as it Moves into the Central Atlantic

Gaston became the 3rd hurricane of the season early this morning (just after midnight EDT) as the storm was moving northwestward into the Central Atlantic about midway between the Leeward Islands and the Cape Verde Islands before weakening back into a tropical storm less than 12 hours later. Gaston is continuing to battle relatively strong environmental wind shear brought about by an upper-level low pressure center positioned to the west of Gaston. Winds flowing counter-clockwise around the upper low are blowing from the southwest while Gaston is moving northwest. These opposing winds are
