NASA Measures Hurricane Maria’s Track of Torrential Rainfall

From Sept. 17 to early Sept. 21, 2017 NASA’s IMERG estimated that rainfall totals greater than 10 inches (254 mm) were common along Maria’s track. IMERG rainfall estimates indicated that more than 20 inches (512 mm) of rain fell over a large part of Puerto Rico. During that period Maria dropped heavy rain in the Leeward Islands, Virgin Islands and Puerto Rico. Credit: NASA/JAXA, Hal Pierce
