Tropical storm warning issued - 07/27/2020 05:07 PM

This one definitely could come close. Some predictions have said a hurricane over the Northern Leewards.

Dr. Soc from St. Maarten has recorded some information from Crown Weather regarding the system.

And the intensity prediction appears to be tropical storm force winds. Bad enough but shouldn't be a major event other than possibly rain.

I hope you’re right, we’ll know in about 2 -3 days when they name it.

It's pretty dusty here at the moment and the Sahara dust forecast looks like it will be here until late Friday and then back on Saturday. Should be interesting to see if this invest comes thru during that small window of time.

Looks like a big rainmaker - woohoo! Just had our cistern emptied and cleaned, so hoping this fills it to the brim.

If you're not aware of it, Storm Carib has an interesting graphic, showing how close a particular storm is projected to come to a particular island. Usually it needs to be a named storm, to have it pre-filled in, but potential tropical cyclone 9 is filled in now.

Thanks..very useful!

Re: Tropical storm warning issued - 07/28/2020 07:37 PM

You're welcome, Mal. I find many of the storm prediction sites are just too complicated for me to figure out. IF the storm is pre-filled in, Storm Carib is very user friendly.

We're just starting to get some rain and wind gusts. Anyone who's interested in watching the storm today can click the Sunset Cam button on our Coconut Breeze Villas website.

Doesn't look too bad so far. Guidance from today puts it a little further away from the BVI than yesterday, and still not a named storm.

Just grey and windy here. A few scattered showers but we're in the clear. Wasn't much of an event in CGB.
