2024 CSU Atlantic Hurricane Prediction


2024 Atlantic Hurricane Forecast

Forecasters at the Colorado State University are predicting that the 2024 Atlantic basin hurricane season will have an extremely active 2024 hurricane season. The season begins June 1st and continues through November 30th.

UPDATED: JULY 9, 2024


On Tuesday, Colorado State researchers raised expectations following a hot start to the 2024 season. Experts are now expecting 25 named storms, 12 hurricanes and six major hurricanes in the Atlantic this year. The center pointed to Hurricane Beryl's record-breaking formation and intensity as indicative of the ongoing extreme conditions in the ocean.

 
Their current (June 11th) and past (April 4th) forecast predicts a 50% more likelyhood (over the averages from 1880 - 2020) for major hurricanes making landfall along the United States coastline and in the Caribbean.

The updated June forecast takes newly available data into consideration as the season commences. Uncertainty remains in the forecast, however, as the atmosphere-ocean system can sometimes change dramatically between this month and the peak of the Atlantic hurricane season, which runs from August–October.

As is customary, NOAA made their first prediction at the end of May. So, why does Colorado State University's team of scientists create an April forecast? Mainly because the public is curious about predictions based on the current global oceanic and atmospheric conditions. The forecasting team created their predictions using a statistical model based on 29 years worth of data.  This is the 41st year in which the CSU Tropical Meteorology Project has made forecasts of the upcoming season’s Atlantic basin hurricane activity.

According to CSU scientists, "El Niño conditions are weakening quickly across the tropical Pacific and are likely to transition to La Niña conditions by the peak of the Atlantic hurricane season. La Niña tends to weaken upper-level westerly winds across the Caribbean and the tropical Atlantic. These decreased upper-level winds result in reduced vertical wind shear, favoring Atlantic hurricane formation and intensification. "

Coastal residents are reminded that it only takes one hurricane making landfall to make it an active season for them, and they need to prepare the same for every season, regardless of how much or how little activity is predicted.

The Juine forecast calls for 23 named tropical storms with 11 strengthening to hurricane status. Of those hurricanes, 5 are predicted to be a major hurricane (Category 3,4, or 5). The team will issue additional forecasts on July 9 and Aug. 6.

The report also includes the probability of major hurricanes making landfall:
 
The team forecasts 62% for the entire U.S. coastline (average from 1880–2020 is 43%),34% for the U.S. East Coast, including the Florida peninsula (average from 1880–2020 is 21%),42% for the Gulf Coast from the Florida panhandle westward to Brownsville (average from 1880–2020 is 27%), and 66% for the Caribbean (average from 1880–2020 is 47%).

This is the highest predicted number of hurricanes that CSU has ever issued in a June outlook. The prior high was for 10 hurricanes in 2010 (when 12 were observed) and in 2022 (when eight were observed). June forecasts have been issued by CSU since 1984.

Another reason why Colorado State University publishes forecasts is for hurricane preparedness.   We too are publishing this information, along with updates throughout hurricane season, to help protect life and property when danger approaches.

As I've said many times,  the cruise line industry has safety of passengers, crew, and vessels as their number one priority.   The cruise lines work closely with the NHC and other agencies to monitor all sorts of weather conditions, including tropical storms.   The ships may alter courses and cancel ports of call in order to maintain the level of safety for all onboard.  We will keep you posted about any known itinerary changes during hurricane season.   Should your cruise itinerary change due to a tropical storm, don't be upset, but rather thank the Captain and crew for taking you out of harm's way.  Read our blog post 4 Things To Help Plan Vacation in Hurricane Season...

More links and information about tropical storms and other weather conditions can be found in the Weather & Hurricane Zone tabs above.  We will feature several articles during Hurricane Preparedness week once again.   Until then, you can click the link below for last year's series.

Keeping an Eye on Gordon

Tropical Storm Gordon

If you haven't noticed before, we are heading into the most active part of the hurricane season.  Right now there are two storms in the Atlantic and two in the Pacific that are being tracked by the National Hurricane centers. 

The one that has everyone's attention is Tropical Storm Gordon, which should make landfall in the Gulf region sometime tonight as a hurricane.    All the states in its path are on high alert and preparations for heavy rainfall are underway. Gordon is moving toward the northwest near 15 mph (24 km/h), and this general motion is expected to continue until landfall occurs tonight along the north-central Gulf coast.


 

Full coverage of this, and all tropical storms, can be found on our Hurricane Zone page.   There are RSS feeds from the National Hurricane Center posted there giving you up to the minute information.   For storms that impact cruises, we will bring you information on those details as well.  Please bookmark that page for further reference during the Hurricane Season which runs now through November 30th.

SHIP IMPACT:
Royal Caribbean’s Majesty of the Seas ship departed Florida 
just before midnight Monday night September 3rd in order to sail 
behind the storm. The ship will flip its itinerary, but the 
voyage is still expected to make all of its ports of call.

The Port of New Orleans Administration Building will close for 
all nonessential personnel at 2 p.m. Tuesday, Sept. 4, 2018, 
in order to prepare for any possible weather-related activities
due to Tropical Storm Gordon.



A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
in the indicated locations. For a depiction of areas at risk, please
see the National Weather Service Storm Surge Watch/Warning Graphic,
available at hurricanes.gov. This is a life-threatening situation.
Persons located within these areas should take all necessary actions
to protect life and property from rising water and the potential for
other dangerous conditions. Promptly follow evacuation and other
instructions from local officials.

A Storm Surge Watch means there is a possibility of life-
threatening inundation, from rising water moving inland from the
coastline, in the indicated locations.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area. Preparations to protect life
and property should be rushed to completion.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning areas.

HAZARDS AFFECTING LAND
----------------------
STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Shell Beach to Dauphin Island...3 to 5 ft.
Navarre Florida to Dauphin Island, including Mobile Bay...2 to 4 ft.
Shell Beach to the Mouth of Mississippi River...2 to 4 ft.
Mouth of the Mississippi River to the Louisiana-Texas border...1 to
2 ft.

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large waves. Surge-related flooding depends on the
relative timing of the surge and the tidal cycle, and can vary
greatly over short distances. For information specific to your area,
please see products issued by your local National Weather Service
forecast office.

RAINFALL:  Gordon is expected to produce total rain accumulations of
4 to 8 inches over the western Florida Panhandle, southwest Alabama,
southern and central Mississippi, southeastern and northeastern
Louisiana, and southern Arkansas, with isolated maximum amounts of
12 inches through late Thursday. This rainfall will cause flash
flooding across portions of these areas.

WIND:  Tropical storm conditions are expected to begin this
afternoon within portions of the warning area, with hurricane
conditions expected by this evening in the hurricane warning
area.

TORNADOES:  A few tornadoes are possible this afternoon through
tonight near the coasts of Mississippi, Alabama, and the Florida
Panhandle.
