Cristobal Becomes A Hurricane

Cristobal Becomes A Hurricane
Tropical storm Cristobal was upgraded to a hurricane yesterday evening at 8:20 PM (August 26, 2014 at 0020 UTC). The TRMM satellite flew above the newly designated hurricane this morning at 1135 UTC (7:35 AM EDT) providing rainfall data used in this image. A rainfall analysis derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data is shown overlaid on a 1126 UTC GOES-EAST Visible/Infrared image. Cristobal was a category one hurricane with sustained winds estimated to be slightly above 65 kts (about 75 mph) with this view. Cristobal's didn't have a clearly defined eye with

Tropical Storm Iselle Hits Hawaii

Tropical Storm Iselle Hits Hawaii
Hurricane Iselle weakened to a tropical storm while approaching the island of Hawaii on Thursday August 7, 2014. As a tropical storm Iselle contained some heavy rain showers and strong winds when it hit the big island. Iselle later dropped some heavy rain over Maui and scattered showers extended to Kauai and Oahu. The TRMM satellite had an excellent view of tropical storm Iselle as it neared the Hawaiian islands on August 8, 2014 at 0152 UTC ( August 7 at 3:52 PM HST). A rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on a 0200

TRMM Sees Iselle and Julio Menacing Hawaii

TRMM Sees Iselle and Julio Menacing Hawaii
The TRMM satellite saw both weakening hurricane Iselle and category two hurricane Julio in the same orbit as they were moving toward the Hawaiian islands on August 7, 2014 at 0922Z. This image shows data collected by TRMM's Microwave Imager (TMI) instrument with the orbit containing both hurricanes located in the center of the image. Microwave brightness temperatures at 85.5 GHZ and at 37.0 GHZ were combined in the red, green and blue components to construct the image. Recent forecasts of tracks for hurricane Julio and tropical storm Iselle are shown overlaid in white and red respectively.

Iselle Moves Toward Hawaii

Iselle Moves Toward Hawaii
Hurricane Iselle has weakened from a very dangerous category four hurricane on August 4, 2014 to a category one hurricane when the TRMM satellite passed over on August 6, 2014 at 1020 UTC. Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) are shown overlaid on an enhanced infrared image from the 1000 UTC GOES-WEST satellite. TRMM TMI showed that heavy rainfall was occurring around the filling eye. TRMM TMI indicated that the most intense rain was falling at a rate of over 43.5 mm (about 1.7 inches) in a band southwest of the eye. The second image is an animation

Hurricane Iselle Heads Toward Hawaii

Hurricane Iselle Heads Toward Hawaii
The TRMM satellite flew directly over the eye of powerful hurricane Iselle on August 4, 2014 at 1037 UTC. Iselle had winds of about 120kts (about 138 mph) at that time making it a dangerous category four hurricane on the Saffir-Simpson hurricane wind scale. Rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on a GOES-WEST enhanced infrared image captured at 1030 UTC. Rain was found by TRMM PR to be falling at a rate of almost 182 mm (about 7.2 inches) per hour in Iselle's eye wall. Hurricane Iselle is predicted by the National Hurricane

The Global Precipitation Measurement mission's Core Observatory flew over Hurricane Arthur five times between July 1 and July 6, 2014. Arthur is the first tropical cyclone of the 2014 Atlantic Hurricane season. It formed as a tropical storm on Tuesday, July 1 and reached maximum intensity as a Category 2 hurricane on July 4, disrupting some coastal U.S. Independence Day celebrations. This visualization is taken from the flyover on July 3, 2014 with Hurricane Arthur just off the South Carolina coast.

Cristina Now A Hurricane

Cristina Now A Hurricane
Tropical storm Cristina intensified and was a category one hurricane with wind speeds of over 65 kts (about 75 mph) when the TRMM satellite flew over on June 11, 2014 at 1142 UTC (4:42 AM PDT). A rainfall analysis that used data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on an enhanced infrared image received by the GOES-EAST satellite at 1145 UTC. TRMM TMI data clearly revealed that an eye had developed indicating that Cristina was definitely a hurricane. TRMM PR found that rain was falling at a rate of over 74.4 mm/hr (about 2.9 inches) in a

Amanda Weakening

Amanda Weakening
Once powerful hurricane Amanda was weakening to tropical depression intensity when the TRMM satellite passed above on May 29, 2014 at 1038 UTC. A rainfall analysis derived from TRMM data is shown overlaid on a GOES-15 enhanced infrared image. TRMM's Microwave Imager (TMI) found rain falling at a rate of slightly over 47 mm/hr (about 1.9 inches) in storms located between Amanda's center and Mexico's coast. Amanda's locations and intensities are shown in red.
