The National Hurricane Center announced Monday that Tropical Depression 3 has progressed into Tropical Storm Bret.As of Monday night, Bret was 1,210 miles east of the Southern Windward Islands and had maximum sustained winds of 40 mph. It was moving west at 18 mph.According to NHC, Bret could strengthen into a hurricane. "This motion is expected to continue for the next several days. On the forecast track, the system should be approaching the Lesser Antilles late this week," the NHC said. "Strengthening is forecast, and Bret could become a hurricane in a couple of days."Forecasters expect Bret to strengthen over the next two days, reaching Category 1 hurricane strength of 74 mph by Wednesday night. Because of wind shear, the storm is not expected to strengthen into a Category 2 storm.Bret “is forecast to strengthen and move across the Lesser Antilles as a hurricane on Thursday and Friday, bringing a risk of flooding from heavy rainfall, hurricane-force winds, and dangerous storm surge and waves,” the center said.There is a possibility the storm could turn north or continue west into the Caribbean and threaten the Dominican Republic, Haiti and other islands.'Everyone in the Lesser Antilles, Puerto Rico, and the Virgin Islands should closely monitor updates to the forecast for this system and have their hurricane plan in place," the center said.Tropical Storm Arlene, the first storm of the 2023 season, formed earlier this month. It petered out after two days, never threatening landfall.The Associated Press contributed to this report.

The 2021 Atlantic hurricane season, just like the 2020 season, was one for the record books — but for different reasons.The biggest similarity was the high number of named storms. The 2021 season became only the third in history to use all of the names on the rotating seasonal list (the previous years were 2020 and 2005).We ended the season with 21 named storms, 7 hurricanes, and 4 major hurricanes (Category 3 or higher). During an average year there would be 14 named storms, 7 hurricanes, and 3 major hurricanes. This year met or exceeded each of those categories, and it was forecast to be that way. The Atlantic hurricane season runs from June 1 to Nov. 30.There were four major hurricanes this season: Grace, Ida, Larry, and Sam.

"Ida already ranks among the top-five most costly hurricanes on record for the U.S. since 1980."Ida was the strongest Atlantic hurricane of the year to make landfall with maximum sustained winds of 150 mph when it struck near Port Fourchon, Louisiana, on Aug. 29. It was one of only three hurricanes to ever make landfall in the state of Louisiana with winds of 150 mph, the most recent being Laura from 2020."Grand Isle, Louisiana took a direct hit with 100% of its homes damaged and nearly 40% were nearly-to-completely destroyed," according to NOAA. "There was heavy damage to the energy infrastructure across southern Louisiana causing widespread, long duration power outages to millions of people."In the following days the remnants of Ida moved to the Northeast and combined with a frontal system, delivering extreme rainfall rates and flash flooding, inundating streets, homes and neighborhoods.Flash flood emergencies were declared in New Jersey and New York.

The 2021 Atlantic hurricane season, just like the 2020 season, was one for the record books — but for different reasons.

The biggest similarity was the high number of named storms. The 2021 season became only the third in history to use all of the names on the rotating seasonal list (the previous years were 2020 and 2005).

We ended the season with 21 named storms, 7 hurricanes, and 4 major hurricanes (Category 3 or higher). During an average year there would be 14 named storms, 7 hurricanes, and 3 major hurricanes. This year met or exceeded each of those categories, and it was forecast to be that way. The Atlantic hurricane season runs from June 1 to Nov. 30.

There were four major hurricanes this season: Grace, Ida, Larry, and Sam. The strongest two were Ida and Sam, which both reached Category 4 strength. Grace and Larry peaked as Category 3 storms.

The first half of the season was off to the races — as the U.S. was impacted by eight named storms: Claudette, Danny, Elsa, Fred, Henri, Ida, Mindy, and Nicholas.

Then, suddenly, the world's oceans became eerily quiet. After Sept. 25 the Atlantic and the rest of the world would struggle to produce a named storm.

That was not what meteorologists expected.

Both last year and this year La Niña conditions were observed during the last several weeks of the season, which typically favors late season tropical activity. 2020 saw three named storms in November (Eta, Theta, and Iota) and 2021 saw just one (Wanda) during the first few days.

How this hurricane season ended marks one of the biggest differences between this year and last.

Klotzbach explained that usually La Niña weakens or limits vertical wind shear, but surprisingly there was quite elevated wind shear in the Caribbean in October and November — the focal region for storms late in the season — and that led to a quiet latter part of the 2021 Atlantic hurricane season.

While an active season was predicted, it's impossible to know in advance exactly where each storm will go and what kind of damage it may cause.

In 2020 more hurricanes made landfall in the U.S., but this year the storms cost over $20 billion more.

Billions in damage

While only one major hurricane made landfall across the U.S. (Ida), a total of four named storms left behind over $1 billion in damage each: Tropical Storm Elsa, Tropical Storm Fred, Hurricane Ida and Hurricane Nicholas.

Ida alone exceeded the cost in damage of all seven billion-dollar tropical cyclones that made landfall across the U.S. in 2020, including hurricanes like Laura, Delta, and Zeta.

"To date, Hurricane Ida is the costliest disaster this year — exceeding $60 billion," according to the National Oceanic and Atmospheric Administration. "Ida already ranks among the top-five most costly hurricanes on record for the U.S. since 1980."

Ida was the strongest Atlantic hurricane of the year to make landfall with maximum sustained winds of 150 mph when it struck near Port Fourchon, Louisiana, on Aug. 29. It was one of only three hurricanes to ever make landfall in the state of Louisiana with winds of 150 mph, the most recent being Laura from 2020.

"Grand Isle, Louisiana took a direct hit with 100% of its homes damaged and nearly 40% were nearly-to-completely destroyed," according to NOAA. "There was heavy damage to the energy infrastructure across southern Louisiana causing widespread, long duration power outages to millions of people."

Flash flood emergencies were declared in New Jersey and New York. At least 55 people died across New York, New Jersey, Connecticut, Maryland, Pennsylvania and Virginia.

This season's quirks

The strongest storm of the season didn't hit land but video was captured from inside it.

Hurricane Sam, like Ida, also reached Category 4 strength with maximum sustained winds of 150 mph. Sam remained a Category 4 hurricane for 4.5 days and generated the fifth-highest accumulated cyclone energy (ACE) recorded in the satellite era.

"ACE is integrated metric accounting for storm intensity and duration," Klotzbach tweeted. "Sam was a long-lived, intense hurricane."

Fortunately, unlike Ida, Sam remained out over the open waters of the Atlantic and never made landfall.

Sam's long life, of over 11 days as a hurricane, allowed a research drone to be sailed into it, and, for the first time, to transmit video from inside a major hurricane at ocean level.

Ida will likely be the only name on the retired list this year, despite there being three other major hurricanes, simply because of the amount of damage and fatalities caused. The letter "I" already has more retired names than any other letter in the alphabet.

There are already 12 retired storm names that start with the letter "I", and Ida will likely become the 13th.
