The image shows Hurricane Willa on October 22 prior to making landfall. Warm waters greater than 26.5 degrees Celsius (or 80 degrees Fahrenheit) fueled Willa, which is clearly seen as bands of increased precipitation. Surface precipitation rate data is from GCOM-W1/AMSR2 and sea surface temperature data from the Multi-Scale Ultra-High Resolution (MUR) dataset.
