Excellent picture out of Puerto Rico !

Re: ISAAC: Prep,Obs,Cams at L Antilles / BVI / USVI / PR
It's been raining fairly heavily here for the last hour or so and the latest WV satellite loops show that there's plenty more coming our way from the southwest. The same loops also seem to suggest that Dominica recently got pounded with lots of torrential rain but we'll know for sure as reports at StormCarib come through.

Re: ISAAC: Prep,Obs,Cams at L Antilles / BVI / USVI / PR / DR
I just came in from battling the elements out there.
That was scary and awesome.
My preparations to keep my dogs dry couldn;t match the winds.
I walked into a wall of horizontal pelting rain, and we just just had to get the job done.
All dry now, doggies are good, and we put extra barriers in case rainfall maintains so that we could keep out the floodwaters.
Can;t imagine those who've been battling for hours.....

Re: ISAAC: Prep,Obs,Cams at L Antilles / BVI / USVI / PR / DR
We've had quite a bit of rain so far tonight. It's not raining now but I can see from the satellite loops that quite a bit more is on the way from a developing feeder band.
@FireBird
I'm not surprised by your report because that same feeder band is affecting T&T (Trinidad and Tobago).
It's now starting to rain here again and I'm going to bed.
Good Night all. Stay safe.
Zzzz...

Judging by how the ground outside looks, I don't think we had significant amounts of rain since I went to sleep. It's currently overcast with light rain and the winds have noticeably increased during the last 20 minutes or so, gusting to around 35 mph (perhaps more). They appear to be coming from the SSE.

Very good news here. Pretty tranquil night! The red vigilance have been canceled since yesterday night 
because of the cyclonics effects have spared the butterfly island. Whereas since 6AM, we have nice rain showers from the outers bands with moderate to sometimes strong gusts!
Right now, given Meteo-France we're under an orange alert for risk of strong showers and tstorms and rough sea.

Vigilance orange for heavy rains/storms and dangerous sea

http://www.microsofttranslator.com/bv.a ... 183723.php
Storm cells observed in spiral band at the rear of the storm still threaten our islands. Heavy showers are possible along the day.
Storm tropical Isaac centre crossed the Guadeloupe archipelago Wednesday evening, passing on the Petit Cul-de-Sac Marin and southern Earth bass. The center of Isaac is now at about 250 km southwest of Basse-Terre, the Caribbean Sea. The active portion of the storm was located on the margins of its center and has avoided our islands. Rains have still caused rollups of 60 to 80 mm in a few hours on the southern Basse-Terre, Marie-Galante and les Saintes during the passage of the centre of Isaac last night. Grande Terre and Northern bass.
Earth have been spared by these showers, but are affected by low and continuous rain. Large storm cells are still observed on the Atlantic, at the rear of the storm. Southeast wind, low early in the night, strengthened and blows to the
Daybreak at a speed of 40 km/h approximately on the coast, and up to 60 km/h on la Désirade. Finally, the sea has deteriorated strongly last night and is still strong, with average lows of 3 to 4 m, and 6 to 7 m waves. Storm cells observed in spiral band at the rear of the storm still threaten our islands. Heavy showers are possible along the day. The sea remains strong and dangerous until tonight at least. The Southeast wind is still quite maintained and blows at an average speed of 40 to 50 km/h. Gusts can reach 60 to 70 km/h to the passage of showers.

There are pictures of some pretty bad flooding in Trinidad & Tobago at Storm Carib:

Just goes to show you that it's not always where the center hits. Guadeloupe, Dominica and Martinique which seemed to be in Isaac's "bullseye" seem to have gotten off quite lightly, while some of the southern islands got hit with extreme rains and flooding from the heavy southern feeder bands.
A very good lesson and reminder that a storm is not a "point" or a line, and that the exact track and cone is not always what matters in assessing impact. Storm size and the precipitation distribution in the various quadrants of the storm are really important too.
