… about the danger posed by hurricane Florence, nothing will.
The Weather Channel has used green screen technology to graphically demonstrate what different levels of storm surges might look like if you happen to be trapped in it.

A much better use for CGI than mere entertainment, no doubt.
Visualisation for the masses.
Impressive demonstration. That really should help people understand what is going on. Hopefully that convinced more people to evacuate.
I must say I like the global wind map, shows the tropical storm hitting the Philippines too.

The unstated (an incorrect) assumption is that your home and yard are at water level. If the storm surge reaches the max prediction of 9 feet, and your home is built 5 feet above the water level, your home will only be flooded with 4 feet of water, not 9.
I don’t know enough about the areas mapped to to what height they are about water level, but 4 foot is still enough that you should evacuate rather than stay. Furthermore when it comes to the inland areas in rivers it gets more complicated that the height above water, because you are also talking about the water flowing down the river being backed up.
I can’t do audio currently but the layout of the water levels around the map would seem to indicate roughly what sort of water level you should expect at that point. I think you are supposed to use that to determine whether to pay more attention to the demonstration of the 3 feet, 6 feet, or 9 feet demonstration. Accounting for height above sea level appears to be included already.
Intransitive has posted some shots of “just” a heavy rainstorm in Taiwan.
CBC, the last time I caught the news. was calling for a metre of rain and a storm surge of 4 metres for Florence but that was a couple of hours ago so things may have improved or worsened.
For all those brave (==fffing stupid) people planning on riding out the storm; with any luck the Coast Guard may find your bodies.
Typhoon Mangkhut, heading for the Philippines, Guangdong Province, Hong Kong, and points west is even more powerful than Florence. A CBC interview with, IIRC, the Red Cross head of disaster relief suggested that the Philippines was expecting a lot of devastation due mainly to a weaker infrastructure than a place like the USA.
From some interviews in the South China Morning Post, people in Hong Kong were taking precautions and some evacuations were in progress but no one seemed too worried. Presumably due to much better infrastructure and extensive experience with typhoons.
I thought it an impressive visual but a little lacking in sharks.
My brothers were in Germany years ago when the Elbe flooded. I remember the descriptions of how dangerous even knee deep water was with the current rolling debris around.
Why not go for the real deal? This is why every Dutchman (though I’m not sure of the young generations) is afraid of water:
It was not even a hurricane, “only” a combination of a heavy storm and spring tide.
They are also warning to watch out for land slides, even in the mountains.
It’s been raining in normal fall amounts the last week here in Texas. The “Turn around don’t drown” commercials are back on the radio. Evacuation may be impossible later.

Indeed, that is the best place to watch for landslides. They are not a serious problem on flat land.
