Hi Luis!

We finally had some rain today, a couple of brief but very heavy showers! Wind gusts to 24kt reported by one captain from a thunderstorm near our airport.

Looks like Martinique/Dominica going to have some heavy rains tonight.

Buoy 41100 had winds over 20kt from 7am to 3pm today, highest hourly report was 26kts, or 30mph.

Lightning getting really frequent, thunder louder. The lights have already dimmed a couple of times, I'm unplugging the computer! Looks like some good rain tonight.

GREAT lightning show going on and thunder as well...I came home from housesitting afraid I'd left my windows open...nope, I didn't, but I like it better here, hardly any light but the sky show. Looks like some big rain coming in soon. Good!

#286 Postby **cycloneye** » Thu Jul 27, 2006 6:41 am

A stormy night here with heavy thunderstorms overnight and early this morning.Winds also haved been fairly strong in the range of 20-25 sustained with some higher gusts between 30-35 mph in the squalls.A rainy day is on tap for us in this holiday day in Puerto Rico.

#287 Postby **bvigal** » Thu Jul 27, 2006 6:56 am

Good morning, neighbors! Wow, what a show overnight. If I'd had a water-proof camera and some nerve, I could have gotten pics of some incredible lightning - big fat bolts down to the water, and networks of them across the sky. Thunder that went on for 10-15seconds at a time. It was almost like daylight out there, the lightning so frequent. Radar shows since 1:22am parts of our islands had 2-3" rain, but it started raining much earlier than that. As expected the power went out shortly after the big boomers arrived. Mine came back on early this morning, but some areas are still off. One of the big potted palms on the balcony blew over last night, so a gust of at least 40mph to do that. Right now it's very hazy and grey cloudy skies.

The cool air feels wonderful and the gardens are happy! Hopefully there will be no flooding on PR.

#289 Postby **bvigal** » Thu Jul 27, 2006 7:10 am

Some more thunderstorms south of St. John are headed your way MJ. Hopefully they won't last too long!

bvigal,no major flooding occured with the wave passage as the bulk of the precipitation passed just to our north.Also the strong winds moved the showers that made it into PR move fast so no big accumulations occured.

caribepr · #292 Postby **caribepr** » Thu Jul 27, 2006 5:39 pm

Really not much rain here either, after a nice shower this morning...the coolness gave way to still humidity. We can't tell if it is haze, ash, dust or what that is hanging in the air. But the gardens DO love the rain water!!

#293 Postby **cycloneye** » Fri Jul 28, 2006 3:47 pm

Good afternoon to all.It was a very windy day here with gusts between 27-32 mph.Let's see what effects there will be when the next wave moves thru tonight and tommorow.

ANTILLES LATE THIS AFTERNOON...WILL CONTINUE MOVING QUICKLY WEST
NORTHWEST TOWARD THE LOCAL AREA EARLY TONIGHT...THEN PASS ACROSS
THE U.S. VIRGIN ISLANDS AND PUERTO RICO LATE TONIGHT THROUGH EARLY
SATURDAY NIGHT. THIS WAVE WILL RESULT IN A SIGNIFICANT INCREASE
IN SHOWERS AND THUNDERSTORMS AND WINDS ACROSS THE LOCAL ISLANDS.
WSR-88D ALREADY SHOWING BANDS OF SHOWERS AND THUNDERSTORMS MOVING
QUICKLY WEST NORTHWEST AND APPROACHING ST CROIX AND EXPECT THIS
WEST NORTHWEST MOTION TO CONTINUE TONIGHT...ALLOWING CLOUDINESS...
SHOWERS AND STORMS TO GRADUALLY SPREAD ACROSS THE LOCAL ISLANDS.
THE WAVE WILL CONTINUE TO MOVE ACROSS THE LOCAL AREA THROUGH
SATURDAY...RESULTING IN A GOOD DEAL OF CLOUDINESS...SHOWERS AND
STORMS AND VERY GUSTY WINDS. EXPECT SOME LOCALLY HEAVY
RAINFALL...BUT QUICK CELL MOTION TONIGHT THROUGH AT LEAST THE
FIRST PART OF SATURDAY...SHOULD KEEP MOST FLOODING IN THE URBAN
AND SMALL STREAM ADVISORY. THE TROPICAL WAVE WILL MOVE AWAY FROM
THE LOCAL REGION LATE SATURDAY NIGHT THROUGH SUNDAY...WITH A
GENERALLY DRIER AND MORE STABLE AIR MASS EXPECTED FOR LATE SUNDAY
THROUGH TUESDAY. WE WILL BE WATCHING THE TROPICAL WAVE...APPROACHING
40 DEGREES WEST AT THIS TIME...CLOSELY OVER THE NEXT FEW DAYS. A
FIRST GUESS FROM THE GFS WOULD HAVE THIS WAVE NEAR THE LOCAL
ISLANDS DURING THE LATE WEDNESDAY/THURSDAY TIME FRAME.

&&

.MARINE...THE APPROACHING TROPICAL WAVE WILL RESULT IN A
SIGNIFICANT INCREASE IN SHOWERS AND THUNDERSTORMS...WINDS AND SEAS
ACROSS THE REGIONAL WATERS BEGINNING TONIGHT AND CONTINUING

Good morning fellow Caribbean members.A gray,windy and rainy day is on tap for Puerto Rico as the wave moves thru.I recorded wind gusts from 26-34 mph this morning.

#296 Postby **bvigal** » Sat Jul 29, 2006 7:08 am

Good morning all! We had NO rain yesterday or overnight, being just above the dividing line of the squalls from this tropical wave. Of all the Virgin Islands, St. Croix has had the bulk of the rain/wind.

caribepr · #297 Postby **caribepr** » Sat Jul 29, 2006 7:17 am

Wind wind and more wind. A bit of rain starting now, but very slow drips more than real rain. It looks like pre-dawn light though...really dark.

#298 Postby **bvigal** » Sat Jul 29, 2006 8:52 am

It sure is building in now, lots of little yellow and red blobs materializing on the radar to our east. Will have some rain to go with the 5ft seas in the channel and 20+mph winds.

caribepr · #299 Postby **caribepr** » Sat Jul 29, 2006 12:17 pm

I'm starting to think our radar is whacked. It was down for repair, and now...green means clouds and yellow means rain. Or seems to. It's that brassy light now, rain on and off. I opened the cart, sold some hot sauce, closed the cart and decided I was giving up for the day. Of course now it looks like it won't rain again...grrrrrrrr! And the wind has gone flat as well. Ah weather!

caribepr · #300 Postby **caribepr** » Sun Jul 30, 2006 6:28 am

Holy cow! Some serious rain all night, still going on now (but much much more calmly)...lightning, thunder, raging rain - thankfully it woke me up as the place I'm housesitting has windows that were WIDE open on the weather side and before the place was soaked I woke up and got them shut. Luckily I'd left the upstairs ones closed..
Incredible...I'm really curious how much rain we got (are getting)!
