Consider this...
Did you know that this all volunteer website depends on donations from visitors like you? I need them to cover the expenses I incur by running the Caribbean Hurricane Network. Unfortunately, donations are well below 'normal', probably because of the COVID-19 related economic crisis on the islands. So if you love this unique website featuring original content, and you don't want it to disappear, you can show your support by visiting the donations webpage. Thank you so much! -Gert

Today we ran out of storm names, second time ever. Unfortunately this doesn't mean that nature thinks it is enough as well for this season. Now we are going to dip into the Greek alphabet, which might be later today... [actually as I write this, Alpha was just announced]

First our biggest threat, Teddy, now a Category Four Hurricane! It is still heading straight towards Bermuda. However, a turn is still expected before reaching The Rock. The forecasted track has trended a bit to the east again, with the closest point of approach now at 130 miles (yesterday it was 75 miles) early Monday. Indeed, looking at the European and American ensemble model output (see below, adapted from, we can at least now see the little speck that is Bermuda outside the different model run tracks. However, the storm is still 2+ days away, so things can still change,it is still too close for comfort. Better be prepared than sorry when dealing with a major hurricane! Also, Teddy is producing large swells that can reach the islands. So it might be a good time to go boogie boarding, but be careful!

Elsewhere, the tropical wave we were following (98L) is now Wilfred, the last name on the official list. It still should move north of the islands, and even if it doesn't it looks like it will have weakened into a tropical wave before it even gets here.

Then we have Tropical Depression Twenty-Two in the Gulf of Mexico. That might become a hurricane, but the biggest threat will be the rain. It is a very slow mover, especially later in the forecast when it moves along the coast of Texas... Expect widespread flooding again...

Finally, about 3500 miles away we have Subtropical Storm Alpha, off the coast of Portugal (yes, that country in Europe!). It is expected to be short lived Looking at the storm tracks in my climatology-section, it seems not to be the first time that Portugal gets hit, but it is a rare occasion. Stay safe everybody! (and sssshhhhhtttt, tomorrow is going to be a special day for a special person). -Gert

Thursday, September 17, 2020 09:54AM PDT - Teddy-Bermuda
Ugh, that satellite picture above looks scary! Teddy is now a major Category 3 hurricane, packing 120 mph winds. It is expected to further strengthen... And right now it is moving straight towards Bermuda. However, a weather system coming off the United States in a few days should curve Teddy more to the north. The timing of that turn is crucial for Bermuda. Right now both the European ECMWF and American GFS model predict that Teddy will pass just east of Bermuda. See image below adapted from, with the pink arrow pointing to the little speck that is "The Rock". Indeed, the closest point of approach is now 75 miles to the east on Monday (see below). Hope the trend continues driving Teddy more to the east... Regardless, people on Bermuda should get prepared for another hit, this one will be stronger than Paulette, but hopefully further away...

Elsewhere, Sally is still drenching the US but is rapidly weakening. Invest 98L looks to follow Teddy's path, so moving nicely north of the islands (hopefully not again towards Bermuda!). Stay safe everybody! -Gert

Wednesday, September 16, 2020 10:20AM EDT - Sally and others

Good morning!Â

It's a busy morning again so let's get to it.

Hurricane Sally: Landfalling as I write. The northern eyewall has made landfall around Mobile Bay while Gulf Shores AL will become the official landfall. Gulf Shores and Pensacola FL are feeling the brunt of the eastern side with up to 30 inches of rain falling already with more to come while a dangerous storm surge still has a way to go, 5.5 ft in Pensacola so far. Hurricane force winds are already spreading inland. With 90 mph sustained winds gusting to 110 mph, Sally is expected to weaken rapidly while her forward motion is not so much at 3 mph. It means a prolonged pounding wind wise and rain wise and this will be, in the end, a catastrophicÂand historic event weather wise. She arrived as a strong Cat 2 and is now a strong Cat 1. Those who did not evacuate have made many distress calls but conditions are too dangerous for first responders. In their defense, which I usually do not defend people who do not evacuate when told to, this storm shifted east pretty quickly so close to the coastline that they really didn't have time to evacuate. Mother Nature threw a curve ballÂstarting towards southern LA and even potentially farther west, then curved in over the plate of Alabama instead. Sally will remain dangerous for the next few days. All that rain that falls to the north has to go somewhere. The surge and southerly winds are not allowing the rains that have already fell to drain into the sea so flooding will be a longer lasting damaging issue.

Hurricane Teddy: Looking ominous off to the east of the Antilles and Caribbean, Teddy is expected to become a beast of a bear; not the fluffy cuddly kind we are used to with a name like Teddy. Teddy is going to grow up rapidly and a Category 4 monster is expected within the next 36-48 hours due to low wind shear, no dust interference, and warm SST's. Fortunately, it should avoid the islands of the Antilles but due to a westward shift in the track courtesy of a stronger high pressure steering current, Bermuda, once again may be in the bullseye after being beat up by hurricane Paulette. Colder waters and increasing wind shear should knock Teddy down to a Cat 2 or Cat 1 by that time but still, 2 in a row.

Hurricane Paulette: After ravaging Bermuda, Paulette is now transitioning to a strong extra tropical storm with still potent 100 mph winds but a threat now to only the fish and shipping lanes. Even by Monday she is expected to still be at tropical storm force but no further threats expected.

TS Vicky: Located NW of the Cabo Varde Islands, packing 50 mph winds, she is affecting only the fish and shipping while expected to become a remnant low by or on Friday.Â

99L: Located a few hundred miles to the NE of the Azores, a non tropical system has a 20% of acquiringÂat least subtropical characteristics while moving south and east. No threat at this time nor projected to be.Â

There is an area of interest not assigned a number yet in the SW Gulf of Mexico that has an opportunityÂto become at least a TD during the next few days. Regardless, heavy rains will affect the Mexican coast.

98L: The one we in the Caribbean should be wary of for now. Moving west at 10-15 mph, conditions look good ahead for the formation of a tropical depression and with the strong steering high pressure system to the north, lack of dust and warm SST's this could be a problem in the Caribbean in 7-10 days. Time will tell.

Stay safe and prepared!!

NWS National Hurricane Center Miami FL
200 AM EDT Sat Sep 19 2020

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical 
Storm Beta, located over the western Gulf of Mexico, on Hurricane 
Teddy, located over the central Atlantic, and on Tropical Storm 
Wilfred, located over the eastern tropical Atlantic. The National 
Hurricane Center has issued its last advisory on Alpha, which 
became post-tropical over northern Portugal.

Post-Tropical Cyclone Paulette is moving southward and is now 
located just south of the western Azores. The cyclone is forecast to 
continue southward for the next day or two and then stall over 
marginally warm waters a few hundred miles south of the Azores. The 
cyclone could subsequently develop tropical or subtropical 
characteristics by early next week while it moves little. For more 
information about marine hazards associated with this system, see 
High Seas Forecasts issued by Meteo France. 
* Formation chance through 48 hours...medium...40 percent. 
* Formation chance through 5 days...medium...50 percent.

A tropical wave is located near the west coast of Africa and will 
move westward over the far eastern Atlantic during the next few 
days. Development of this system, if any, will be slow to occur 
during the next few days.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 5 days...low...10 percent.


Public Advisories on Tropical Storm Wilfred are issued under WMO 
header WTNT33 KNHC and under AWIPS header MIATCPAT3. 
Forecast/Advisories on Tropical Storm Wilfred are issued 
under WMO header WTNT23 KNHC and under AWIPS header MIATCMAT3.

High Seas Forecasts issued by Meteo France can be found under WMO 
header FQNT50 LFPW and available on the web at

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

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 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 Gert
