Tropics 11-15

Another disturbance is expected to crop up near the Gulf of Mexico sometime this week, according to the National Hurricane Center, but it's expected to move away from Louisiana. 

The non-tropical area of low pressure is expected to develop near the coast of southern Florida within the next couple of days, hurricane forecasters said Wednesday morning. Though forecasters said the system is not likely form into a tropical depression or storm, it could bring gusty winds and heavy rain to parts of southern Florida and the Bahamas as it moves northeast along the U.S. East Coast. 

The system had a 10% chance Wednesday of forming into a tropical depression or storm in the next seven days. 

Disturbance in the Caribbean

A disturbance over the southwestern Caribbean Sea could develop into a tropical depression or storm by the end of this week, according to the National Hurricane Center. 

Though it's too early to tell exactly where the disturbance is headed, hurricane forecasters said Wednesday morning that they expect it to move northeast past the Gulf of Mexico and toward the Greater Antilles.

Forecasters said those with interests in Cuba, Jamaica, Haiti, the Dominican Republic, the Bahamas and the Turks and Caicos Islands should monitor the progress of the system, which is producing a broad area of showers and thunderstorms and is likely to bring heavy rain to the Caribbean and Central American coasts this week. 

The system had a 50% chance Wednesday morning of forming into a tropical depression or storm within the next seven days, down slightly from earlier predictions.

The busiest time of hurricane season  

We've exited what is historically the most active period of the Atlantic hurricane season

Peak hurricane season

In the last 100 years, the tropics have been the most active in August, September and October, with Sept. 10 being the peak of the Atlantic hurricane season, according to federal forecasters. (graphic via NOAA)

In the last 100 years, the tropics have been busiest from mid-August through October, with Sept. 10 being the peak of the season, according to federal forecasters. About 80% of the systems that have hit the Gulf Coast formed during this time, according to the National Weather Service in Slidell.

The 2023 hurricane season

The return of El Niño was initially expected to bring a wetter second half of the year to Louisiana and a reduced risk of hurricanes.

The National Oceanic and Atmospheric Association's Climate Prediction Center announced March 9 that La Niña, which usually causes more hurricanes to form in the Atlantic, was officially over after an unusually long three years.

El Niño and its sister La Niña are part of the El Niño-Southern Oscillation cycle, a set of conditions over the Pacific Ocean that affects weather patterns across the world. In Louisiana, the biggest effects involve hurricane season in the Atlantic Ocean.

Regardless, this year's first cyclone hit in January, long before the official start of hurricane season, and June alone saw three named storms. Now forecasters are predicting that 2023 will prove to be an above-average hurricane season, with 18 named storms. 

The first tropical storm to form in the Atlantic this year was named Arlene, reaching wind speeds of 40 mph on June 2 as it headed for Cuba. Don was the first storm to reach hurricane status in 2023, producing maximum sustained wind speeds of 75 mph on July 22 before rapidly weakening to a tropical storm the following day. 

The next storm to form will be named Vince. Here's the full list of this year's storm names.
