Hurricane Henriette, located a little over 1,770km (~1100 miles) east of Hawaii, was still intense with winds of 90kts (~103.5 mph) this morning. The National Hurricane Center (NHC) predicts that Henriette will weaken tomorrow as it moves over cooler waters and encounters west-southwesterly wind shear. Henriette's track was overlaid on a Sea Surface Temperature (SST) analysis that was derived from observations by the TRMM Microwave Imager (TMI) radiometer. Sea Surface temperatures have to be warmer than 26 °C for tropical cyclones to survive and this analysis indicates that hurricane Henriette

The TRMM satellite flew over the eastern Pacific Ocean on August 6, 2013 0233 UTC (~5:33 PM local time) collecting data for the low sun angle views of hurricane Henriette shown here. The Visible/Infrared image on the left shows the shadows cast by towering thunderstorms on the northeastern side of Henriette's forming eye wall. The image on the right shows the same image with rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments overlaid. TRMM's PR instrument measured rain falling at the rate of over 55.46mm/hr (~2.2 inches) per hour in this towering

The TRMM satellite had an excellent day time view of dissipating tropical depression Flossie as it was moving to the northwest of the Hawaiian Islands on July 30, 2013 at 2348 UTC (1:38 PM HAST). An analysis of rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) is shown overlaid on a combination visible and infrared image from TRMM's Visible and InfraRed Scanner (VIRS) instrument. This analysis shows that very little precipitation was then occurring near the center of the weakening tropical cyclone's circulation. The most intense rain was found by TRMM to be falling at a
