- Heating up MDR
Good night everyone,
The lull is over and I hope everyone used that time to finish preparations for the upcoming slingshots that will be firing off the African coast for the next 8-10 weeks or so. Each one from now on has potential, whether right off the bat upon splashdown like the one falling off land tomorrow or the one that puts you to sleep, lazily wandering across the MDR until it's almost upon you which is what a lot of the lowriders do. Let the 93% of this season commence.
91L, which menaced the Cabo Verde Islands as it moved northward, has now poofed and no threat to develop. However, it's remnants are expected to take a left turn Clyde and head west while under that steering high pressure ridge with regeneration a possibility and a sneaky one at that as all eyes will be farther south if it does.
So, farther south is a very vigorous wave that the NHC has been monitoring the last few days and has given it a 40% chance of development within the next 5 days while still over land. Forecast to move generally west under that same steering high pressure, it will be a thankful beneficiary of the wave in front of it's generosity, by soaking up that dry Saharan Dust and moistening the atmosphere ahead. With that moist atmosphere and low to moderate wind shear, this wave should develop as long as it stays generally west. This could setup up a collision with the Northern Antilles mid to late next week. Could. Not in stone. If the ridge breaks down before the islands in time, we would have an early season "fish storm", a welcome sight.
Closer to the islands around 45W, that benefactor wave in front has a chance as well but it will be a rougher go as it has to master the dust surrounding it as it is forecast to move more to the WNW. This also puts it on a possible collision with the northern islands and where it goes after passing them is anyone's guess.
These last two waves have also been mentioned as possibly threatening the east coast which will depend on the strength of that strong high pressure at that time if they are developed in the first place. But that's another story or hopefully a non story down the road.
Stay safe and prepared!
Monday, August 2, 2021 11:05AM PDT - All still quiet
- Just got back from St.Maarten/St.Martin. Had a fantastic time on the Friendly Island, beautiful beaches, gourmet food. Although on vacation I was still keeping an eye on the tropics, see below (But what is up with the cans of Presidente? Why can't I buy bottles in the stores anymore?). No storms in sight! There is only one wave close to the Cape Verde's that has a low chance of development. Quiet for August, hope it stays that way! -Gert

- Quiet on all fronts. For now...
Good morning all from Germany,
First, prayers and condolences to all affected by the catastrophic flooding in Western Germany, Belgium and Holland. The worst flooding is roughly 2.5 hours west and southwest of where my wife and I are staying. While this is the Caribbean Hurricane Network, I cannot ignore the human devastation and physical destruction so close to me which happened so quickly and somewhat unexpectedly. Flooding to some level was forecast possible but 2 months of rain in one day plus residual rains before and after was not even fathomed. The surreal pictures tell many stories which leaves one speechless in it's ferocity and terror.
The Atlantic and the Caribbean, on the other hand, is devoid of calamity for the present time as, after a very fast and frantic start, a lull and a sense of calm has enveloped the region. Saharan Dust, dry and hazy, continues to play tag with the continuous African wave train with the dust winning at almost every turn, reducing active splashdown off the African coast waves to mere shells of their former formidable selves. However, the lull, while welcomed, will be short lived and a few of those waves will unfortunately be the tag-ers and somewhere in the Caribbean, GOM, and east coast will be the tag-ees.
Looking ahead in the short term, nothing stands out except for the omnipresent dust. As shared earlier, waves exit the African coast but are reduced quickly by a steady diet of dryness to the north, wringing out the wave like you would a squeegee. There are a couple waves approaching the islands currently with the first very weak and the second with much more moisture content with not much else. In about a week, models suggest tropical cyclone formation is probable off the South Carolina coast and/or south of Newfoundland. Obviously not in our arena but still, if this manifests, will be a probable sign our lull might be over.
Complacency sucks. Be prepared.

- Caribbean says bye Elsa
Now, for the second time a minimal hurricane, Elsa is finally out of the Caribbean arena and jumped headfirst into the GOM. Lashing the lower west coast of Florida with a trailing scorpions tail still stinging the Keys, Elsa, at the moment about 45 miles off to the west of Sarasota, could intensify just a bit more before finally taking a header north of Tampa if the track holds as forecast. Hurricane hunters are currently in the storm and have found a wobbly system still trying to get more organized. The upgrade to hurricane status was based on land based radar readings with the HH in there now trying to confirm. A 5 mph uptick will not make much difference in Elsa's effects though. The longer she is over water, the potential for strengthening does remain though. However, it won't be the wind that does the most damage right away. It will be the storm surge. The wind and flooding rains will pick up the damage slack. After Florida, Elsa looks to take a tour of the whole east coast. She sure will have come a long roundabout way from the coast of Africa to visit the Statue of Liberty.
Back to the Caribbean and the MDR, the most prominent features are 3 tropical waves and an expansive, copious amount of Saharan Dust stretching from the Cabo Verde Islands east to the Lesser Antilles west while dipping below 10N and above 30N. This over 2500 mile stretch of moderate to heavy dust concentrations will severely inhibit any system traveling close to or through from trying to become the next name in an already record setting tropical season just 1 month and 6 days old. if this layer was dipping below 10N just a week ago, we probably would not have had an Elsa before reaching the Caribbean, if at all.
The wave closest and furthest south is below 10N around 66W with blustery, rainy conditions affecting the lower Windward islands and Trinidad/Tobago. Too close to South America now, it might be interesting in the Western Caribbean. The middle wave is wimpy around 44W with not much of a future for the time being as it's too close to the dipping SAL around 10N, while the third wave, also a 10N lurker at 29W, has more convection than the middle one but also is being suppressed by the omnipresent SAL.
There is a 4th just launching off the African coast with impressive size and not enveloped in dust. Time will tell if it keeps it's composure or poofs under the dust onslaught. Even if it does, the wave train will send more so don't let the lull in action, lull you.
Be prepared and stay safe!

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
A tropical wave just inland over Africa is producing a large area of
showers and thunderstorms over the Guinea Highlands. This wave is
expected to move off the west African coast later today.
Environmental conditions appear somewhat conducive for gradual
development, and a tropical depression could form over the eastern
tropical Atlantic by early next week while the system moves westward
to west-northwestward at about 15 mph.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...50 percent.
A tropical wave located over the central tropical Atlantic is
producing a broad area of disorganized showers and thunderstorms.
Environmental conditions are expected to be marginally conducive for
some slow development east of the Lesser Antilles by early next week
while the disturbance moves west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

|- - - 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 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!

Weather discussions also by Dave McDermott, St.Thomas, USVI.
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
