Thursday, May 23, 2024 10:39AM PDT - Another 'above-normal' forecast
NOAA just issued their forecast for the season. They say that there is an 85% of an above-normal activity season with 17-25 tropical storms, of which 8-13 hurricanes and 4-7 major hurricanes (14.4, 7.2 and 3.2 is normal, resp.). They blame the near-record warm sea surface temperatures in the Atlantic and the likely development of La Nina which enhances storm formation due to reduced wind shear. Apart from La Nina, 'near-record' temperatures will become more normal due to human induced climate change, so it does not bode well for the future... You can read more about the record heat in Michael Lowry's post on Eye on the Storm/Yale Climate Connections. Regardless, chances are still quite low that your island will get hit, but they are increasing. See the table in my previous post.

In NOAA's news release they also talk about some improved communications (for example, all advisories will now be in Spanish as well, not just the Public Advisory, also tropical storm watches and warnings can now be issued any time instead of in a regular advisory). They also mention new tools and system upgrades. Hope it all helps since the main key to minimize losses is being well prepared.

Lastly, there is a little disturbance northwest of Haiti. It is moving to the east. Although it is not expected to develop into something, heavy rains are still expected over Hispaniola and Puerto Rico. Stay safe everybody, and start some preparations now! Hurricane seasan is just over a week away... -Gert

Monday, April 8, 2024 10:18AM PDT - Another 'hyper-active' forecast
Tropical Storm Risk, recently absorbed by EuroTempest, a European storm and weather risk management services to the (re)insurance market, has issued their forecast for the upcoming season. It is exactly the same in number of storms as the one by Klotzbach et al's (see earlier post). They also call for a 'hyper-active' season with 23 tropical storms, 11 hurricanes, and 5 intense hurricanes.

They say: "The reason why the TSR extended forecast for the 2024 Atlantic hurricane activity calls for a hyper-active season is our expectation that the warm sea surface temperature anomalies currently present in the Atlantic Main Development Region (MDR) and Caribbean Sea will persist through August-September 2024, and a moderate strength La Nina event will develop through spring/early summer and persist through summer and autumn.". Indeed, high water temperatures and La Nina conditions means bad news for us. Read the full report here.

Another 'hint' to start preparing now! In reality there is still a relatively small chance that a 'big one' will end up on your doorstep (see the table in my earlier post), so don't get too worked up about these forecasts. But you will feel better if you are well prepared. This might be a good year to invest in those hurricane shutters, if you don't have them already... -Gert

Thursday, April 4, 2024 10:15AM PDT - Extremely Active Hurricane Season forecasted...
Today Klotzbach and his team at Colorado State University issued there well respected forecast for the upcoming season. And it is not looking good... This may come as no surprise, since last year we had the battle between El Nino, which decreases hurricane activity, and warm sea surface waters, which increases hurricane activity. El Nino lost... This year we won't have an El Nino, but La Nina conditions, which normally enhances hurricane activity, plus the record warm sea surface temperatures are still here!

The forecast calls for 23 (!) named stormes (14.4 is normal), of which 11 are expected to reach hurricane strength (7.2 is normal) and 5 reach major hurricanes status (3.2 is normal). This is the highest number of storms ever forecasted by Colorado State in April...

The major drivers are La Nina and high sea surface temperatures. Although we are still in an El Nino, it is expected to fade in the next few weeks, and transform to La Nina conditions at the peak of hurricane season. During a La Nina vertical wind shear is lower in the Atlantic, making it easier for tropical storms to develop and become stronger. Sea surface temperatures in the tropical Atlantic are currently at record levels, see for example the last plot on the my satellite imagery page (yellow/orange means above normal, it looks like 1-2° Celcius or more above normal!). And it is expected to stay above normal, giving more fuel to hurricanes...

Normally the April forecast doesn't have much skill, but this year they are more confident that there will indeed be an active season. It is hard to argue otherwise, with record sea surface temperatures and an La Nino, two of the main drivers in hurricane activity...

What does it mean for the Caribbean... For the Caribbean region the probability of at least one major hurricane tracking through the region (a big area) is 66% (normal is 47%, last year it was 49%). In the table below I summarized the chance of a major hurricane moving within 50 miles of a specific Caribbean island/country compared to the long term average (1880-2020) (source: https://tropical.colostate.edu/TC_impact.html). Note that some of the numbers are biased by area, for example The Bahamas. In any case, just one big storm in your backyard is more than enough. It seems that this is the season that you invest in some good hurricane protection.... Preparation will be key this season.

A good writeup can also be found on Jeff Masters' Eye on the Storm blog at Yale Climate Connections. It does not really make you happy reading it... -Gert

- - - Local hurricane correspondents wanted! - - -

The local hurricane correspondents are the heart and soul of stormCARIB. They are the people who live on the island and write to us what is going on around them. First hand very local personal reports instead of very limited or sensationalized coverage by the general media. Do you live on one of the islands? We need your help! We are looking for more people who are interested in sending us a few paragraphs about the situation on your island before, during and after a storm hits. You don't need to be a weatherman or expert on the subject, just share with us what you know, feel and see on your island. Your help will be really appreciated by Caribbean people living abroad with family living on the islands, future visitors who have their Caribbean dream-vacation booked, etc.etc. Reliable, not-sensationalized information is just so hard to get in crisis situations. Help keep the rest of the world up-to-date with what is really happening! We really need you, Georges back in 1998, and many others since then are proof! If interested, contact gert@gobeach.com.


WHAT TO FIND ON StormCARIB.com:
This website is all about the Caribbean. Here you can find information, weather discussions and local reports regarding tropical systems threatening the Caribbean islands. A central part of this website is the volunteer network of special local hurricane correspondents, living on the islands, who will report, when need be, on how it looks and feels like around them. Above also hopefully easy to understand weather discussions by me and Dave. In addition, as an aid in locating family or friends on the islands in an emergency situation you can post your 'plea for help' on the bulletin board. Also featured on this website is the Quick Hurricane Web Resource Navigator, for easy locating to the least overloaded webserver for National Hurricane Center advisories and the latest satellite images. Another part of the Caribbean Hurricane Network is the 'practical guide' to hurricane tracking with unit conversions, definitions, tips, links, etc. You can also find out how close the storm is and how many hours you have left to prepare plus you can map the closest point of approach of a hurricane to your location. New is the climatology of Caribbean hurricanes section. Find out when the real peak of hurricane season is for individual islands, view hurricane tracks passing by the islands over the last 150+ years. An archive with detailed reports of how the Caribbean islands fared during the 2007, 2006, 2005, 2004 (incl. Frances and Ivan), 2003, 2002, 2001, 2000, 1999 (incl. Floyd and Lenny), 1998 (incl. Georges and Mitch), 1997 and 1996 seasons are still available as well. Plus there is more, like storm-centered satellite images, make your own local satellite loop, etc. Hope you find the information on this website (now counting over thousands pages with original content) helpful. Comments always welcome! RSS web feed available. As a side note I am now accepting donations as well. Thanks for visiting!

Keep in mind that my statements are my own interpretations from the information available to me. Therefore, use the information at your own risk, and above all, don't use these webpages for making life-or-death decisions, always rely on the official and qualified authorities!

The author can not be held responsible for lost property, ruined vacations and the like. Despite all this I hope you found the webpage informative and useful. These pages do not have a commercial intent. GoBeach Vacations provided the means and opportunity to start all this. 'Unfortunately' this website has become too popular, placing too much load on the gobeach.com webservers.
