So far this year, no tropical cyclones have formed near Australia. A tropical low is now getting better organized in the Indian Ocean off Australia's northwestern coast. The GPM core observatory flew over this area of disturbed weather on January 27, 2016 at 0946 UTC. GPM's Dual-frequency Precipitation Radar (DPR) instrument measured rain falling at a rate of 96.7 mm (3.8 inches) per hour in towering convective storms within spiraling bands around the tropical low. GPM's Radar (DPR Ku band) made 3-D measurements of convective storm top heights. Some storm tops were found to reach altitudes of

Tropical cyclone Corentin was the first named tropical cyclone of 2016 in the South Indian Ocean. Corentin caused little danger because it's genesis, maturation and dissipation have all occurred over the South Indian Ocean about equidistant from the distant shores of Madagascar and Australia. The GPM core observatory satellite flew over Tropical Cyclone Corentin on January 25, 2016 at 1306 UTC. High vertical wind shear was starting to take it's toll on the increasingly disorganized tropical cyclone. Rainfall collected by GPM Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR)

The Washington, DC area is about to get hit with a record-level snow storm, with attendant disruptions to work schedules, travel, communications, and power. If you find that the TMPA-RT products drop out, it is safe to assume that some combination of these effects is preventing production, and we will work to restore service when that is possible.

The GPM core observatory satellite saw a tropical cyclone developing in the South Indian Ocean east of Madagascar on January 21, 2016 at 0146 UTC. GPM's Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) measured precipitation in the potential tropical cyclone. The most intense showers were shown by the GMI instrument to be dropping rain at a rate of over 71 mm (2.8 inches) per hour in strong storms to the northeast of the tropical low's center of circulation. GPM's radar (DPR) viewed a swath of data to the west of the developing tropical cyclone center where rain was measured

Stormy weather moving in from the Pacific Ocean has frequently affected the Pacific Northwest over the past week. Moisture moving over the Washington and Oregon coasts has been transformed into snow at colder and higher elevations in the Cascades. Coincidentally a field campaign called The Olympic Mountain Experiment (OLYMPEX) is being led by NASA in the Olympic Peninsula of Washington State from November 2015 through February 2016. An analysis of precipitation that occurred in the Pacific Northwest during the period from January 12-19, 2016 is shown here. This precipitation analysis from
