The TRMM satellite has now been making highly accurate measurements of rainfall from space for fifteen years. TRMM can be used to calibrate rainfall estimates from other additional satellites. Those Rainfall data (3B42) are routinely created and stored at the Goddard Space Flight Center. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center can be used to analyze rainfall over a wide portion of the globe. The TMPA analysis above shows the estimated amount of rain contributed by named tropical cyclones over the western Atlantic in
The remnant low pressure center from tropical storm Debby is predicted to kick up winds to gale force and cause a few showers today as it passes to the northwest of Bermuda. The TRMM satellite passed over the low early this morning at 0717 (4:17 AM ADT). TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data show that Debby's remnant low contained a few light to moderate showers. A 3-D view using TRMM PR data shows that the most powerful of these storms were only reaching heights of about 10km (~6.2 miles).
Even though it never became more than a tropical storm, the residents of northern and central Florida will remember Debby. Debby, which formed as a tropical storm on the 23rd of June 2012 in the central Gulf of Mexico, took three full days to reach the Big Bend of Florida just 350 miles away. Although the center didn't make landfall until around 5 pm on the afternoon of the 26th when it crossed the coast near Steinhatchee, Florida, Debby's effects were felt well away from the center. Most of the rain and weather associated with Debby were well to the north and east of the center over Florida
Tropical Storm Debby formed on the 23rd of June 2012 in the central Gulf of Mexico, becoming the earliest 4th named storm on record. Debby began as an area of low pressure that moved out of the northwestern Caribbean and into the Gulf. After forming on the afternoon of the 23rd, Debby has moved very slowly under the influence of weak steering currents. Debby drifted ever so slowly northward on the night of the 23rd before turning northeast later on the morning of the 24th towards the northeast Gulf Coast of Florida. Despite its slow forward progress and lack of intensification, Debby has
The TRMM satellite traveled directly above tropical storm Debby's location early this morning at 0656 UTC ( 2:56 AM EDT). TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data from that pass shows that Debby was dropping heavy rainfall in a large area on the eastern side of the Gulf Of Mexico. Most of the powerful convective storms producing this rainfall are shown by TRMM to be located well to the northeast of Debby's center of circulation. A forecast track from the National Hurricane Center (NHC) was overlaid on the image above. It shows that Debby is expected to stengthen and travel
