Hurricane Sam continued its advance across the Atlantic on Wednesday with strong winds and away from land, two cases that will continue until next week, when it actually reaches the northern part of the ocean.
The US National Hurricane Center (NHC) noted that Sam remains a Category 4 hurricane on the Saffir-Simpson scale (1 to 5) with maximum sustained winds of 130 mph (215 km/h), although there are volatility.
At 0500 (0900 GMT) Sam was about 445 miles (730 km) east of the northern part of the Leeward Islands and was moving northwest at 9 mph (15 km/h).
There are no coastal watches or warnings in effect due to the passage of the seventh hurricane in 2021 in the Atlantic basin, a major hurricane that did not make landfall in its full course.
NHC expects Sam to maintain its all-out northwest movement with increased travel speed through Friday, when it is expected to head north.
On the forecast track, Sam will pass east and northeast from the northern Leeward Islands today, which are not slated to touch.
Anguilla, Barbuda, Antigua, Saint Barthelemy, Monserrate, Guadeloupe, Dominica, Saba and Saint Kitts and Nevis are the main Leeward Islands, which are part of the Lesser Antilles.
Some fluctuations in Sam’s intensity are expected over the next few days, but it will remain a strong hurricane over the weekend.
Hurricane-force winds extend up to 40 miles (65 km) from the center and tropical storm-force winds extend up to 125 miles (205 km).
Storm created by Sam will hit the Lesser Antilles over the next few days and is expected to reach Bermuda and the Bahamas within two days and then spread across the eastern coast of the United States later this week.
These bulges can cause both life-threatening and existing conditions.
There are currently three low pressure systems in the Atlantic Basin that can lead to hurricanes, which are most likely to be hurricanes the furthest from the American continent.
So far this year, seven hurricanes have formed in the Atlantic basin: Elsa, Grace, Henry, Ida, Larry, Nicholas, and Sam. Among them Grace, Ida, Larry and Sam reached the highest category, 3 or more on the Saffir-Simpson scale.
