Good night all,
It has been some season so far, this 2019 Atlantic Hurricane season, and as it draws to it's historical climax on November 30th after a prolonged period of weak, short lived systems, relative quiet, and the Azores taking the surprisng brunt of late season activity, Mother Nature says "It ain't over till I say it's over!". With that, TS Sebastien was declared from the seedling formerly known as 90L as of the 11am advisory, today November 19th.
Located about 300 miles NE of the Leeward Islands, Sebastien has been earmarked for potential development since Saturday. Asymmetrical in appearance due to strong westerly wind shear (20+ knots) shoving dry air into his tiny COC, Sebastien's convection is almost entirely on the eastern side of that COC.
Down the road, Sebastien is supposed to turn North then Northeast and be eventually absorbed by a cold front. Increasing in speed forward wise, he has the chance of increasing strength as well due to a lessening of wind shear, warm enough SST's, and baroclinic processes (which occurs in the form of wind energy from warm air rising and cold air sinking forming vorticity).Â Sebastien might reach 60-65 mph as an extra tropical storm before dying a rapid death in the North Atlantic. No land masses will be involved or impacted at this point.
Sebastien makes the total 18 named storms, 6 hurricanes with 3 intense hurricanes for this season so far. Above average activity yes. Will there be another one? Maybe. Sounds like alot but 8 or so of these storms were short lived with not much impact on land masses; only theÂname score.
Have a good night everyone!

- One more named storm (hopefully) before the end of hurricane season. Sebastien, storm number 18 for this year. Although only about 275 miles from the Leeward Islands it is no threat to the islands. The system is currently moving north northwest, and might get a bit closer to us, but then it will veer off to the east. Hopefully the last storm until June 2020!!! -Gert
Monday, November 18, 2019 07:56AM PST - Possible something?
- Hurricane season is almost over, but we have an invest a few hundred miles east of the Leeward islands. There is a 50% chance that it could become tropical storm Sebastien. Luckily is is not moving towards the islands, but more north. Also, even if it becomes a tropical storm it will be (another) short lived storm. -Gert

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 email@example.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!

The information on these pages is derived from weather statements provided by the National Weather Service, the National Hurricane Center, and others, and from hurricane correspondents in the Caribbean. I tried to translate the official weather statements in more layman's terms. Also, I tried to fill the gap in reporting on what is happening in the Caribbean, instead of the US (there are already many other good website which focus on the US). 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! Accuracy of eye-witness reports by the special hurricane correspondents have not been checked. They may be highly subjective. 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. Luckily, starting in 2000, my excellent webhost provider, pairNetworks, liked my website so much that they support services whenever they can. Comments are always welcome. Just send a note to email@example.com. Gert
