NASA Monitors Tropical Depression 05W in NW Pacific

Tropical Depression 05W (TD05W) also known as Dodong in the Philippines was caught by infrared NASA satellite imagery on June 8 at 1741 UTC (1:41 p.m. EDT). The infrared data showed some powerful thunderstorms with very cold cloud top temperatures near the threshold of AIRS data of -63 Fahrenheit and -52 Celsius. That indicates the coldest, strongest thunderstorms within the tropical depression. Some of the strongest thunderstorms at that time were over western Luzon and stretched out over the South China Sea….
