The GPM core observatory satellite had another excellent view of tropical cyclone Vardah (05B) in the eastern Bay of Bengal on December 8, 2016 at 0301 UTC. GPM found that Vardah had become better organized since it formed on December 7, 2016. Maximum sustained winds had increased to an estimated 45 kts (~52 mph). GPM's Microwave Imager (GMI) showed that two intense feeder bands were bringing moisture from the Andaman Sea into the northeastern side of the tropical cyclone. GPM's Dual-Frequency Precipitation Radar (DPR) coverage is shown in a slightly lighter shade through the center of the

A tropical cyclone (TC05b) formed on December 7, 2016 in the eastern Bay Of Bengal. The Joint Typhoon Warning Center (JTWC) issued it's first advisory when TC05B was located just west of the Andaman and Nicobar Islands with winds of 35kts (~40 mph). On December 6, 2016 at 1441 UTC the GPM core observatory satellite passed over the forming tropical cyclone. This image shows a rainfall analysis that was derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data. GPM's radar (DPR Ku band) showed that the forming tropical cyclone had two bands of convective storms

The mountains of Mauna Kea and Mauna Loa in the Hawaiian Islands have recently received heavy snowfall. Hawaii's balmy temperatures normally reach above 80 degrees Fahrenheit (27 C) at sea level on beaches such as Oahu's Waikiki but temperatures fall below freezing at the altitudes of tall mountain peaks on the Big Island. At 13,802 feet (4.2 km) Mauna Kea is Hawaii's tallest mountain. Snowfall is frequently seen on Mauna Kea's peak. The nature of precipitation in the Hawaiian Islands was recently examined using data collected by the GPM core observatory satellite. GPM flew over the Hawaiian

On Tuesday evening through Wednesday morning tornadoes formed along a squall line in advance of a cold front that moved through the Southeast. Over three dozen tornadoes were reported with sightings occurring in Louisiana, Alabama, Mississippi, Tennessee and Alabama. Tornadoes caused the deaths of a least five people in northern Alabama. Storms also took the the lives of two people in Tennessee. This Rainfall may provide some relief to drought ridden eastern Tennessee where destructive wildfires have been occurring. Some storms were accompanied with hail, strong winds and intense showers. Golf

Hurricane Otto hit the southern coast of Nicaragua on November 24, 2016 at about 1800 UTC (1 PM EST). Otto had winds of about 95 kts (109 mph). The hurricane crossed into Nicaragua just north of the town of San Juan de Nicaragua that is located at 10.9 degrees North latitude. This makes Otto the southernmost land falling hurricane in Central America on record. Otto dropped flooding rainfall as is weakened and moved through northwestern Coast Rica. Otto was still a well organized tropical storm when it moved into the Eastern Pacific early on November 25, 2016. Otto's maximum sustained winds had

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

Scattered to numerous showers and scattered thunderstorms have occurred over Hispaniola during the past week. Slow moving frontal systems draped over Hispaniola and a tropical wave recently caused heavy rainfall that led to wide spread flooding over the northern Dominican Republic. Over 20,000 people have been displaced from their homes and at least five deaths have been reported. A broad area of low pressure (90L) in the southwestern Caribbean is also being monitored for possible tropical cyclone development by the National Hurricane Center (NHC). Very warm sea surface temperatures and upper

Tropical cyclones have been forming frequently in the Western Pacific Ocean since July 2016. 36 named tropical cyclones have formed in the Western Pacific in less than 5 months with 14 of them becoming typhoons. Tropical Depression MA-ON Formed on November 10, 2016 northeast of Guam. MA-ON had maximum sustained winds estimated at 30 kts (34.5 mph) when the GPM core observatory satellite flew over on November 10, 2016 at 0701Z. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that the tropical depression contained some very heavy showers. Strong bands

A tropical disturbance that recently formed in the Bay Of Bengal may cause heavy rainfall in the next few days along coastal India's eastern state of Odisha and southern Bangladesh. The low is predicted to move northeastward over the warm waters of the Bay Of Bengal but according to the Joint Typhoon Warning Center (JTWC) has only a medium chance of developing into a tropical cyclone. High vertical wind shear is forecast to keep the tropical disturbance from intensifying. The GPM core observatory flew above the low on November 4, 2016 at 0026 UTC. GPM saw that the low contained some strong
