UPDATE – AUGUST 29:
14 H 00
Our content creator and presenter, Véronique Saumure, will fly to Florida Friday and will be on hand to explain the situation.
13 H 00
21 million people live in Florida, and nine million live on the east coast of the state. The authorities have called them to prepare food, and the shelves of grocery stores are starting to empty. More than 300 mm of rain are expected.
In addition to the arrival of the system, the tide will be high in several areas, including near the cities of Miami and Daytona Beach. The National Hurricane Center warns that flash floods can occur and cause fatal accidents.
Forecasters expect Monday morning, when the tropical system will touch the ground, the winds are over 210 km / h.
Here's what Dorian looks like from the International Space Station:
Dorian will land in Category 4, the strongest hurricane to hit the east coast of Florida since Andrew in 1992. This hurricane is recognized as one of the most expensive in the state.
It is expected that it will strengthen and expand. At present, its diameter is about 250 kilometers. It could reach nearly 385 kilometers.
Hurricane winds extend out to 30 km from the coast. The central and tropical winds extend up to 150 kilometers.
The trajectory deviated, the island of Puerto Rico was relatively spared. Indeed, if heavy rains fell and large gusts blew, Dorian quickly moved to Florida.
The hurricane will become category 3 as of Friday, two days earlier, than originally planned. This means that this extra period could potentially allow him to have more time to gain intensity before touching Florida's shores.
Dorian continues his ascent north-west. A weaker ridge is expected to affect Florida and the Georgia border, while stronger ridges will fall near South Florida.
It will reach the status of major hurricane during the next two days and keep this status until it arrives on Earth.

UPDATE – AUGUST 28:
The state of emergency has been declared for 26 counties in Florida. Forecasters expect the hurricane to hit the state early Monday morning, with the first violent bursts starting Saturday night.
The National Hurricane Center issued warnings related to heavy gusts and heavy amounts of rain. Sudden flood risks are also expected in the risk areas below.

The Bermuda High will push the system eastward, directly above the area where conditions will favor energy gain.

On September 2, 1935, hurricane Labor Day Hurricane struck South Florida in Category 5. It was the most violent system in the state's history, until it was dethroned in 1992 by Hurricane Andrew .
Its winds were 295 km / h and its pressure was 892 mb, the lowest pressure ever recorded for a hurricane that affected the United States.
At present, the Dorian winds are at 120 km / h. It is Category 1 and passes over the Virgin Islands.
A gust of 178 km / h was recorded at Saint Thomas. A pleasure boat was filmed near the eye of the cyclone.
Florida is particularly vulnerable to storm surges.
Dorian left more than 120 millimeters of rain in Martinique and Guadeloupe, in addition to gusts of more than 100 km / h. At present, the disturbance continues to run less than 50 kilometers from the Virgin Islands in the United States with winds of 110 km / h.
On Wednesday, it is expected that it will affect these islands as well as Puerto Rico, bringing more than 150 millimeters of rain. Serious floods and landslides are possible. Dorian will leave the Greater Antilles by Thursday, where conditions will be favorable for it to form a hurricane before reaching the coast of the United States. This would be the second hurricane of the season.
It is important to note that Puerto Rico is still recovering from Hurricane Maria, which hit Category 4 from September to October 2017. Confirmed damage has been estimated at more than US $ 91 billion.
The factors contributing to hurricane development in Tropical Storm Dorian are combined: warm surface waters and low wind shear. However, because of the presence of dry air, it is still in the storm stage.

Dorian made landfall on the small island of St. Lucia in a tropical storm this Tuesday and continues to affect the Lesser Antilles. It has lost some intensity because of the interaction of these winds with the islands.
More than 100 mm of rain has already fallen on the side of Martinique and gusts up to 100 km / h have been recorded. In addition, the sea is rough on the Atlantic side with waves up to three meters. Between 50 and 100 mm will be able to fall during the next hours on the Antilles before Dorian moves away in the Caribbean Sea.
Dorian will continue to move northwest to Puerto Rico and the Dominican Republic by Wednesday night to Thursday. She will still face unfavorable conditions during her trip to the Caribbean Sea that will prevent her from becoming a hurricane despite the warm waters. The dry air will still be very present.

There are still uncertainties about the regions that will be most affected because of its trajectory that may change to the west-northwest because of the position of the anticyclone. Quantities between 100 and 200 mm will be expected especially in the high ground.
Dorian will approach Florida later, crossing the Bahamas by the weekend. Residents will have to expect bad conditions for this long weekend. More details on rainfall amounts and wind strength will be available over the next few days.
