The tropics are not slowing down as we begin September with two active tropical cyclones in the Atlantic, both of which formed on Monday.
A hurricane warning is in effect for much of coastal Belize, while tropical storm warnings extend into Mexico’s Yucatan peninsula and Guatemala.
Tropical Storm Nana formed in the Caribbean Sea on Tuesday afternoon and is continuing on a west track.
Nana is expected to strengthen as it moves closer to land due to low wind shear and warm waters, and it could potentially reach hurricane strength before making landfall in Central America.
The storm will bring strong winds and dangerous storm surge to coastal cities, while the threat of heavy rain and flooding will spread farther inland.
Meanwhile, in the western Atlantic, Tropical Storm Omar continues to move away from the U.S. as it tracks east at 13 mph. It’s well north of Bermuda in open ocean. Stronger wind shear and colder waters will help break Omar down, causing it to dissipate over the next few days.
Fast Start To Hurricane Season Continues
Nana and Omar’s dual developments on Monday mean that the Atlantic is already up to 15 named storms so far this season – far more than the 12 named storms that develop over the course of an average full season.
Nana and Omar also became the earliest N and O-named storms on record in the basin, and the 2020 Atlantic season continues to outpace the 2005 season in terms of record-setting early development.
Another tropical wave is coming off the coast of Africa, entering the Atlantic. For now, chances are medium for further development within the next five days.
A second tropical wave is centered between Africa and the eastern Caribbean which has a low chance of development over the next five days.
We’ll be watching both.
The average peak of the hurricane season is approaching and tropical systems can develop just about anywhere in the Atlantic basin this time of year.
In the first ten days of September, they have formed anywhere from the Gulf of Mexico to off the coast of Africa and everywhere in between. This is also the time of year when some of the strongest hurricanes happen.
