Friday, September 22, 2017 09:42AM PDT - Maria is leaving
Maria is finally moving away from the Turks & Caicos. It passed a bit closer to Grand Turk than I expected, only 30 miles, not 50 miles. Maximum sustained winds are at 125 mph (still a Category 3 (major) hurricane). Hurricane force winds extend outwards up to 70 miles, so they were within that range. It is slowly moving at 8 mph towards the northwest. There is a tropical storm warning for the Central Bahamas but Maria should stay a safe distance.

Still not many reports coming in from my hurricane correspondents on Puerto Rico, St.Croix or Dominica. I had just received a text from Isabel, a long time correspondent on St.Croix. She seems fine, but also wrote "We don't have phone service but can occasionally send text messages. No internet.". I also do have contact with our Dave on St.Thomas. He is in good spirits, but looking forward to a hot shower. Hopefully Maria was the final one for this year, we are too tired for a third big one! -Gert

Thursday, September 21, 2017 09:59AM PDT - Still a Cat 3
Finally some time to post again... The situation in Dominica does not seem that good reading CDEMA's first assessment (posted here). I still haven't heard from my hurricane correspondents on the island, due to the poor communications. Hopefully we will hear soon. First reports from St.Croix are not too bad, relatively spoken. Although I don't have a good handle on how the west/south side fared. The same for Puerto Rico, where there apparently is no power on the whole island... And as can be seen on the image above, the rain has not stopped for Puerto Rico, causing flooding and dangerous mudslides in the mountains...

Maria is not done yet, while going over Puerto Rico it weakened a bit, but it is still a Category 3 (major) hurricane with 115 mph winds. Currently it is about 90 miles from Puerta Plata (north coast Dominican Republic), but is slowly at 9 mph moving away from it. The north coast should be just outside hurricane force winds that extend outward up to 60 miles, but within tropical storm winds (extending outward up to 150 mph).

Next target for Maria is the Turks & Caicos Islands, which were hard hit by Irma two weeks ago (175 mph winds..., see Irma and Maria below, two major hurricanes within 2 weeks). The large eye should stay clear of the islands, although the Closest Point of Approach with Grand Turk is only 50 miles... The storm might also strengthen a bit more, now it is back over open water. For the low lying TCI the storm surge will pose a significant risk as well. -Gert

Wednesday, September 20, 2017 06:37AM PDT - Dominica + St.Croix
I have just created Pleas for Help forums for Dominica where people can post or communicate with each other about missing persons, property, other news sources, Ross University School of Medicine, etc. There is also another website: (Caribbean Emergency and Weather Network, run by HAM radio operators) where people can register. Their website is overloaded right now though...

I have also created a similar forum for St.Croix, find it here en Vieques here. Hope it helps.

The situation regarding Maria... After skirting by St.Croix it weakened a bit but still passed as a strong Category 4 storm by Vieques who just got the eyewall, and then made landfall near Yabucoa, Puerto Rico at around 6AM this morning. Right now the center is near the northern coast, just 30 miles east of San Juan. It is then expected to pass near the north coast of the Dominican Republic and just to the east of the Turks & Caicos in 36 hours. -Gert

Tuesday, September 19, 2017 22:20PM PDT - Just
Looks like the eye wall is just reaching St.Croix, see picture below. It could have been worse, but south shore (where the airport is as well) and west side is getting hammered... -Gert

Current Tropical Weather Outlook (NHC/TPC):
Accompanying satellite image (pop-up, source: NHC)
NWS National Hurricane Center Miami FL
200 PM EDT Fri Sep 22 2017

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

The National Hurricane Center is issuing advisories on Post-Tropical
Cyclone Jose, located a little over a hundred miles south-southeast
of Nantucket, Massachusetts, and on Hurricane Maria, located just to
the north of Grand Turk Island.

A small area of low pressure, associated with the remnants of Lee,
is located over the central Atlantic Ocean almost a thousand miles
east-southeast of Bermuda.  The low is producing a concentrated area
of showers and thunderstorms, although the circulation appears
somewhat elongated.  Some additional development of this system is
possible during the next few days while it moves slowly northward
through early next week.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 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

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
