With Labor Day 1 week away, National Hurricane Center tracking 2 tropical waves (2024)

Hurricane Hone brought up to 15 inches of rain to Hawaii over the weekend as it passed south of the Big Island Sunday as a Category 1 storm.

Another possible threat this week could be Hurricane Gilma, currently located just over 1,200 miles east of Hilo. And after a quiet start in the Pacific, the National Hurricane Center also is monitoring a third tropical system in the eastern Pacific, Tropical Storm Hector, which is expected to strengthen as it moves west.

With Labor Day a week away and Florida schools already in session, the best advice from forecasters is to not let your guard down when it comes to storms in the Atlantic basin.

AccuWeather forecasters are predicting "a major shift in the weather pattern will soon blow the doors wide open for a frenzy of tropical activity to unfold."

"I think things could get very active potentially very quickly here as soon as that dry air goes away," AccuWeather Lead Hurricane Expert Alex DaSilva said.

"We could see a parade of storms. This dramatic increase in activity will start at the end of August and persist throughout September," AccuWeather said. Labor Day 2024 is on Sept. 2.

Between six and 10 tropical systems are predicted for September, according to AccuWeather meteorologists. That's similar to the pace of the record-breaking 2020 hurricane season which had 10 September storms. The same year saw a record 30 named storms in the season.

Florida and the Carolinas are at an elevated risk of a landfalling tropical storm or hurricane, AccuWeather said But they aren't the only states that should monitor the tropics closely.

"I'm still very concerned about the Texas coast," DaSilva said.

In its August forecast update, Colorado State University predicted the probabilities of at least one major hurricane making landfall in Florida on the U.S. as:

  • Entire continental U.S. coastline: 56%
    • The average from 1880-2020 is 43%
  • U.S. East Coast Including Peninsula Florida (south and east of Cedar Key): 30%
    • The average from 1880-2020 is 21%
  • Gulf Coast from the Florida Panhandle (west and north of Cedar Key) westward to Brownsville: 38%
    • The average from 1880-2020 is 27%

In its two-week forecast for Aug. 20 through Sept. 2, Colorado State University is predicting normal hurricane activity, but added "environmental conditions look to get more conducive for tropical cyclone activity toward the end of August."

"There is a potential for tropical cyclone formation in the eastern/central Atlantic as well as the Caribbean in 8-14 days. Some of these ensemble members are aggressive with intensification, which makes sense given the low shear that is forecast in week two across the basin," said CSU.

Here's the latest update from the NHC as of  2 p.m. Aug. 26:

The National Hurricane Center was monitoring two tropical waves in the Atlantic basin, according to the 2 p.m. advisory. The Atlantic basin consists of the northern Atlantic Ocean, Caribbean Sea and Gulf of Mexico.

  • First wave: This tropical wave is located in the eastern Atlantic north of the Cabo Verde Islands. It's moving west at 11 to 17 mph. If you're plotting it, it's near 22W, from 20N southward.
  • Second wave: The second tropical wave is located in the central Atlantic east of Puerto Rico. It's also moving west at 11 to 17 mph. If you're plotting it, it's near 48W, from 20N southward.

Expect to see new 'cone of concern' with next named storm, if it nears Florida, US

TheNational Hurricane Center launched its new "cone of concern" for Hurricane Ernesto on Aug. 14.

Ernesto stayed well away from Florida and the U.S., so residents didn't see many differences between the original and new cone. One of the biggest differences between the two is that the new cone will show wind warnings issued for interior counties, not just those on the coast.

Both cones will be visible on the Hurricane Center's website. Find the new cone by going to thegraphics page for the storm,then click on "New Experimental Cone," which will behighlighted in red.

Differences you'll see:

  • Watches and warnings for inland counties, not just coastal areas.
  • White transparent shading for the entire five-day forecast, instead of white stippling (dots) for the four- and five-day forecast.

Who is likely to be impacted?

It's too early at this time to determine if there will be any impact to Florida or the U.S. from the tropical waves.
