The TRMM satellite had a very good view of Cristobal on August 28, 2014 at 1258 UTC (8:58 EDT) as the hurricane passed well to the northwest of Bermuda. Rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data is shown overlaid on a 1300 UTC GOES-EAST Visible/Infrared image. TRMM PR found some intense thunderstorms producing rain at a rate of almost 78 mm (about 3.1 inches) per hour in a band of precipitation feeding into Cristobal's southeastern side. The next image is a simulated 3-D view (from the west) of Cristobal's rainfall structure using radar reflectivity

Cristobal, still a minimal Category 1 hurricane on the US Saffir-Simpson scale, has been slowly making its way northward up from the southeastern Bahamas on a track generally parallel to the eastern seaboard. The storm now appears poised to recurve away from the US East Coast and head for the central Atlantic as it begins to feel the effects of an approaching shortwave trough embedded in the westerlies that's moving eastward out of the Great Lakes region. TRMM made an overpass of Cristobal this morning, which is shown in this image taken at 12:16 UTC (8:16 am EST) 27 August 2014. At the time

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

Strong winds and flooding associated with tropical storm Cristobal have caused deaths in the Dominican Republic, Haiti and Jamaica. Rainfall data for the first image above was captured by the TRMM satellite on August 24, 2014 at 1150Z (7:50 AM EDT). Tropical depression four was upgraded to tropical storm Cristobal a short time after that TRMM view. The next image uses data received by TRMM a day later on August 25, 2014 at 1230 UTC ( 8:30 AM EDT). Cristobal was a sheared tropical cyclone with a rain free center so a red tropical storm symbol was used to clarify the location of Cristobal's

Tropical cyclones are frequently forming during this active hurricane season in the eastern and central Pacific ocean. As hurricane Julio was fading in the central Pacific Ocean north of Hawaii, hurricane Karina was forming on August 13, 2013 off the Mexican coast. The TRMM satellite passed directly above the center of intensifying tropical storm Karina on August 14, 2014 at 1927 UTC. A rainfall analysis that used data from TRMM's Microwave Imager (TMI) is shown overlaid on a GOES-WEST image received at 1930 UTC. TRMM TMI showed that storms near Karina's center were dropping rain at a rate of
