Irma Changes Virgin Island Landscape
These NASA satellite images show the widespread browning of the landscape after Irma passed the Virgin Islands. There are a number of possible reasons for this. Lush green tropical vegetation can be ripped away by a storm’s strong winds, leaving the satellite with a view of more bare ground. Also, salt spray whipped up by the hurricane can coat and desiccate leaves while they are still on the trees.

Multi-Sensor Rainfall Estimates
The following NOAA rainfall estimates were produced using both rain gauge and radar rainfall observations.
Irma Shows Up On Seismometers
Low-pitched hums associated with Irma have been measured on seismometers. The noise is likely caused by high winds — which cause tiny motions in the ground — and also by trees swaying in the wind, which also transfers energy into the ground.
