On October 23 at 6:15 P.M. local time the eye of Huricane Patricia hit the west coast of Mexico. This tropical cyclone rapidly weakened and left a clear wet trace over Mexico.
A strong increase in soil moisture resulted from the rainfall excess was captured by NASA’s satellite Mission SMAP. This mission can measure changes in surface soil moisture and here we see the impact of Patricia over land in one of the satellite swaths just 24 hrs after it hit Mexico. The blue colors are an indication for a strong increase in soil moisture.
