Tropical Storm Debby, the fourth
named storm of the Atlantic hurricane season, formed in the central Gulf
of Mexico on June 23, 2012. It was the earliest date on record for the
fourth named storm in a season.
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 June 23, Debby moved very slowly under the influence of weak steering currents. The storm drifted slowly northward before turning northeast on the morning of June 24. Despite its lack of wind intensification, Debby lashed Florida with heavy rain as well as tornadoes.
The Tropical Rainfall Measuring Mission (TRMM) captured this image of Debby when it passed over the storm at 11:51 Universal Time (6:51 AM Central Daylight Time) on June 24, 2012. At the time of this image, Debby was a moderate tropical storm with sustained winds reported at 60 mph by the National Hurricane Center.
The image shows a top-down view of the rain intensities within Debby. Rain rates in the center of the swath are from the TRMM Precipitation Radar (PR), while those in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) and visible data from the TRMM Visible Infrared Scanner (VIRS).
TRMM reveals that most of the rain associated with Debby was well away from the center, which is marked by a white dot. A large area of moderate rain (shown in green) north and east of the center extends from near Tampa Bay all the way around to near Panama City. A large band of intense rain (shown in darker red) lies just off shore, while light (blue areas) to moderate rain covers a broad area of the Florida peninsula. Curved red symbols mark the locations of tornado reports.
Storm speed is what matters most when it comes to rainfall; the slower the storm, the more time it has to rain over a given area. Debby dumped nearly 7 inches of rain on Gainesville, Florida on June 24, the second highest one-day total on record. Numerous other reports of 6 to 10 inches (15 and 25 centimeters) of rainfall were reported.
TRMM is a joint mission between NASA and the Japanese space agency JAXA.

Tropical Storm Debby lumbered slowly
over the southeastern United States in late June 2012, dropping heavy
rain over parts of Florida and Georgia, news sources said. On June 26,
2012, the U.S. National Hurricane Center (NHC) warned of the hazards
that Debby could still bring to the region, including a storm surge,
heavy rains, and tornadoes.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image around 12:30 p.m. Eastern Daylight Time on June 25. Storm clouds stretched from the Gulf of Mexico across Florida and southern Georgia to the Atlantic Ocean.
Around the time MODIS acquired this image, the NHC reported that Debby was located roughly 50 miles (80 kilometers) south-southwest of Apalachicola, Florida. The storm had maximum sustained winds of 45 miles (75 kilometers) per hour with higher gusts.
Among the worst effects of the slow-moving storm was heavy rainfall. Reuters reported nearly 20 inches (50 centimeters) of rainfall in some areas, and MSNBC reported even high amounts. MSNBC reported that hundreds of thousands of residents had been affected, some suffering property damage from tornadoes, and some having lost electricity. As of June 26, the NHC reported, Debby was moving eastward at just 3 miles (6 kilometers) per hour.
