Why is hurricane Dorian so worried?

Hurricane Dorian is feared the worst in the US for several reasons, including the fact that it could become a Category 4 monster before touching Florida next week, Monday or Tuesday.

These are the elements that make Dorian particularly dangerous:

1 – It could be dark when it hits the ground

According to Friday's noon forecast, Dorian is expected to land late Monday or early Tuesday, while it will still be dark on the Atlantic coast of Florida.

"One of the worst things you can do is get dark when the storm hits," said CNN meteorologist Chad Myers. "You hear things move, but you do not know where they come from."

2 – Dorian could blow more than 209 km / h

Forecasters predict that the maximum sustained winds in Dorian's center will be over 209 km / h when it reaches Florida, also reaching Category 4.

If that happens, Dorian would become the most powerful hurricane to hit Florida since Andrew, which was a disaster for the state in 1992.

Such high winds cause catastrophic damage.

According to the US National Weather Service, even sturdy homes can see their roofs and exterior walls tear away. Power poles and trees are torn off with such powerful winds.

Power outages could last for weeks, forecasters say.

3 – Dorian could do the on-site

The cyclonic storm could linger and go "on the spot", causing significant flooding due to accumulated rain.

Heavy rains are forecast over much of Florida – up to 20 inches in parts of the eastern and central parts of the state, according to CNN experts.

Coastal Georgia should also pay attention to heavy rains.

4 – Royal Tides

In addition to bringing wind and heavy precipitation, the hurricane on the Florida coast will be combined with the strongest tides of the year.

The royal tides in Florida begin as early as Friday, and will get worse in the days to come.

They always cause more flooding, even when there is no storm, especially in Delray Beach.

"The fact that this storm hits during the highest tides of the year is very worrying," said CNN senior meteorologist Brandon Miller.

People who live far from the shoreline could therefore be affected by rising water, which could be 8 to 12 feet.

Storm surges north of where Dorian lands "could easily exceed 8 to 12 feet".
