Hurricane Sam is strengthening in the Atlantic; 2 other tropical depressions likely to form this week | Hurricane center


Two tropical lows are expected to form in the Atlantic this week, hurricane forecasters said Tuesday morning.

It is too early to say where they could go. The shaded area on the graph is where a storm could develop and is not a trail.

The National Hurricane Center clears a runway when a tropical depression forms or is about to form.

It was only a week after the violent passage of hurricane Ida that Ronald “Bay-bay” Laborde was finally able to return to his house along the Bayou …

Hurricane forecasters are also tracking two other systems in the Atlantic, including Hurricane Sam, which again strengthened to become a Category 4 storm.

Both should stay in the Atlantic and not enter the Gulf of Mexico.

There are only two names left on the regular list this year: Victor and Wanda. If these are used, this will be the third time in history that forecasters have used a secondary list of names.

Here’s what to know about the tropics starting at 10 a.m. from the National Hurricane Center.

Where’s Hurricane Sam?

Hurricane Sam has strengthened and is reverting to a powerful Category 4 storm, forecasters said Tuesday morning.

At 10 a.m., Hurricane Sam was about 580 miles east of the northern Leeward Islands. It is moving northwest at 8 mph. A turn to the north is expected by Friday. On the planned track, Sam will pass well northeast of the northern Leeward Islands until Wednesday.

The storm has winds of 130 mph and fluctuations in intensity are expected over the next few days, forecasters said. However, Sam is still expected to remain at least a Category 3 storm until the end of this week.

It will be different from last year, when forecasters used the Greek alphabet.

Sam’s swell will impact the Lesser Antilles over the next few days. Swells are expected to reach Bermuda and the Bahamas by midweek and the US east coast by the weekend, forecasters said. Swells could cause potentially fatal rip current conditions.

Sam poses no other immediate threat to land, and no coastal watch or warning is in effect.

Hurricane forecasters were tracking Peter’s remains, which are about 350 miles northeast of Bermuda, on Tuesday.

The system is moving northeast at 10 mph.

Showers and thunderstorms associated with the system have increased, forecasters say, but they are still not well organized.

The system could revert to a short-lived tropical depression, forecasters said.

It has a 50% chance of transforming into a tropical depression within 48 hours.

A tropical depression is expected to form in the coming days in the Atlantic, forecasters say.

At 7 a.m., a low was several hundred miles southwest of the Cabo Verde Islands in the Atlantic. It travels from west to northwest at a speed of 5 to 10 mph.

Environmental conditions should be favorable for further development. It has an 80% chance of transforming into a tropical depression within five days.

Another tropical depression is likely to form within a day or two in the Atlantic, forecasters said.

From 7 am, a disturbance in the far east of the Atlantic shows signs of organization. It is moving west at 10 to 15 mph.

It has a 90% chance of turning into a tropical depression in five days, forecasters say.

Next name available

There are only two more names left on the regular Atlantic storm name list: Victor and Wanda.

Systems are named when they strengthen in tropical storms. Storms Ana, Bill, Claudette, Danny, Elsa, Fred, Grace, Henri, Ida, Julian, Kate, Larry, Mindy, Nicholas, Odette, Peter, Rose, Sam and Teresa formed earlier this season. Elsa, Grace, Ida, Larry and Sam got stronger in hurricanes.

Last year’s hurricane season broke several records, including one for the most named storms on record.

Last year there were so many storms that forecasters ran out of names and had to use the Greek alphabet. This is only the second time in recorded history that Greek names have been used.

Things have changed for this season. If necessary, forecasters will use a list of additional storm names instead of the Greek names.
