Karen is again a Tropical Storm. The center of the storm is well to the west of SBH, midway between St Croix and Puerto Rico, but the outer bands of rain do reach SBH. It appears that there's been about 1/2" of rain in parts of SBH, and the NHC advisory calls for more to come. Likewise, Météo France is still warning of the potential for 40mm/1.6" of rain to come. Heavy seas have caused the desalinization plant to be shut down.

Our Villa Manager was telling me this morning that the island again needs rain -- they're hopeful of getting some from these storms.
 
Our Villa Manager was telling me this morning that the island again needs rain -- they're hopeful of getting some from these storms.
Funny; I always pictured you as the villa manager, if not managing the island itself.
 
That's funny, Kent! The REAL villa manager is the smart one -- she makes me feel like I actually do something useful! As for the island, I've mastered "restaurant French," and my local contribution kind of runs out there.
 
Our Villa Manager was telling me this morning that the island again needs rain -- they're hopeful of getting some from these storms.

Some areas have had a half-inch or so in the past 24 hours. Météo France predicts much more, but I don't believe them. I've got the airport webcam up in one corner of my screen, and a few times I've noticed cars passing by with windshield wipers on, but no apparent deluge. http://st-barth.com/livecam6.html

Speaking of the webcam, I'm intrigued by the excavation work being done airside, just inside the fence. There was a crew of at least six people working up until midnight last night, and a smaller crew is continuing to work today.
 
The 11PM Update. It was raining in St Barth earlier. Dennis, there is a report of 14.2mm of rain in Marigot, about .56 inches. It won't fill your cistern, but it will help.
