Extreme Florida Rainfall Examined With GPM

Extremely heavy rain has recently fallen over Florida. Over 19 inches (482 mm) of rain has fallen in southeastern Florida during the past seven days. Record rainfall has been reported in Fort Lauderdale and West Palm. This extreme rainfall has led to flooding and flight cancellations. 

Extreme Florida Rainfall Examined With GPM

The GPM core observatory satellite flew above southern Florida on Wednesday June 7, 2017 at 6:06 AM EDT ( 1006 UTC). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments revealed the intensity of rainfall within powerful storms that were drenching southern Florida. GPM's DPR measured rain falling at a rate of over 7.5 inches (190.5 mm) in one powerful storm in the Gulf Of Mexico west of the Florida Keys.

A 3-D view of the vertical structure in these extraordinary storms was developed from GPM Radar (DPR Ku Band) data. Those data showed that several thunderstorm tops were reaching altitudes of 9.3 miles (15 km). The most powerful storms were found to have tops that were reaching above 9.5 miles (15.37 km). A few extremely heavy downpours were measured returning radar reflectivity values of almost 61 dBZ to the GPM satellite.
