Hurricane Florence is a Category 2 storm headed for the US's East Coast and predicted to start affecting South Carolina and North Carolina as early as Thursday, according to the National Hurricane Center.
Because of its enormous size and power, the storm has been a recent – if not frightening – muse for earth observation organisations across the globe.
Most of the time optical satellites are being used. Here is a beautiful video that was taken by the camera on board of the Internation Space Station.
What we can not see in the optical imagery though is the amount of water that the hurricane is carrying with it and that is where passive microwaves come into play. The picture below shows the evolution of hurricane Florence as observed by JAXA's AMSR2 and processed by VanderSat.
