Fig. 2 - S3 SLSTR (06.09.2018 at 01:10) - Early 06.09, it was a cat.2 hurricane, down from cat.4 hours before.
Fig. 3 - S3 SLSTR (06.09.2018 at 13:33) - The day after, it reverted to the status of tropical storm.

US National Oceanic and Atmospheric Administration (NOAA) Satellite and Information Service published: "At 2 p.m. September 12, Florence was located about 435 miles southeast of Wilmington, North Carolina and moving northwest at around 16 mph. Hurricane-force winds extend up to 70 miles from the center of the storm, and will begin reaching the coast of the Carolinas by Thursday morning. Hurricane warnings are in effect across the entire North Carolina coast and parts of northern South Carolina, while flash flood watches extend inland away from the coast in both states.

The National Hurricane Center warns that Florence may slow down considerably late Thursday into Friday as it makes landfall, elevating the risk of "life-threatening storm surge" along the coast and high potential for catastrophic flooding as the storm dumps "heavy and excessive rainfall" across the Carolinas.

Before Florece reached the US coast, Disater Charter wrote: "Florence is the most powerful storm to threaten the Carolinas in almost thirty years with current sustained wind speeds of over 140mph. The region could be without power for several days. Storm surge is also predicted to flood large areas. A state of emergency has already been declared in Virginia, Maryland, Washington DC as well as North and South Carolina. Officials have already asked residents in low-lying coastal areas to leave their homes with a million people expected to evacuate."

One can see how sea surface waves caused by Florence wind only weaken far away from the eye. Important storm surge was observed on the south-east coast of USA. At least 45 people were killed directly or indirectly by Florence, the economic toll should exceed one billion dollars of damage.
