Nana Makes Landfall Early Thursday Morning

Hurricane Nana made landfall in Belize not long after midnight early Thursday morning. Nana became a hurricane just east of Central America late on Wednesday night, making it the fifth hurricane of an exceptionally busy Atlantic season to-date.

What You Need To Know

  • Nana is back to a tropical storm after a brief time as a hurricane
  • Heavy rain and flooding are a threat in Central America
  • Omar has weakened to a tropical depression as it heads out to sea
  • Two tropical waves in the eastern Atlantic have a chance of developing further

Nana first formed as a tropical storm in the Caribbean Sea on Tuesday afternoon, becoming a hurricane just hours before landfall.

The storm will bring strong winds and dangerous storm surge to coastal cities in Belize and Honduras early Thursday, while the threat of heavy rain and flooding will spread farther inland. 

Northern Guatemala and southern Mexico could also feel heavy rain and gusty winds from Nana as it moves inland. It’ll quickly fall apart over the next day as it crosses over mountains.

Meanwhile, in the central Atlantic, Omar has weakened to a tropical depression far from land, well north of Bermuda. Strong wind shear and colder waters have taken their toll on the storm. Omar is expected to dissipate on Thursday or Friday.

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 approaching the Cabo Verde Islands in the far eastern Atlantic Ocean. Chances are fairly high 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.
