GPM Sees Twin Towers in Hermine (IMAGE) NASA/Goddard Space Flight Center Caption GPM's DPR instrument saw strong storms near the center of Tropical Depression Hermine on the evening of Aug. 31. Two "hot towers" are seen to the right of the low pressure center (south and east of the center), which are labeled "T1" and "T2." The "L" indicates center of Hermine and the red color shows a 20-dBZ radar reflectivity up to 14 km high.
