Hey there are you here in Jamaica right now?[/quote]

He lives in Ottawa,Canada but he gets information from the islands, (I dont know how he gets those) [/quote]


thanks cycloneye for replying for me yeah caribgirl, i wish i was in jamaica now but no im not. i live in the Niagara Peninsula of southern ontario..i follow the weather in the caribbean very closely, i use all kinds of sources. Love reading this thread a lot though. Chockful of info. Cycloneye is a genius when it comes to the weather, i wish we could elect him president of puerto rico well hes president of this thread, no one will dispute. Stay safe caribgirl and keep us updated with the weather in Jamaica! You should get your own rain gauge.


UPDATE Sun Oct 21/12 630pmET I'm hearing no complaints in the weather world today from those in the Eastern Caribbean! Apart from the heat which isn't abnormal this time of the year. Just a few brisk showers overnight in St Vincent ( 2mm at Arnos Vale) and 5 mm at VC Bird Int in Antigua. A record 33mm of rain fell also at the airport in St Thomas Virgin Islands.
Dry air in the mid-levels of the atmosphere has kept any widespread showers at bay. There was an area of thunderstorms that developed over mainland Venezuela less than 100 miles SW of Trinidad..these formed in the heating of the day. Thunderstorms in the predawn and dawn hours this morning dropped 72mm of rain at Hato Airport in Curacao..that is close to 3 inches of rain! That must have sent the cacti into chaos LOL

You're chock full of info too it seems but you're right cycloneye is a great resource person. I'll look into getting a rain gauge. I must say though this potential system if freaking me out.

Caribwxgirl, searching the net I found this from Jamaica in another forum.

October 21, 2012 at 5 p.m.

*** INCREASED RAINFALL EXPECTED FOR THE BEGINNING OF THE WEEK……WITH POSSIBLE STORM CONDITIONS BY MID-WEEK
***

An Area of Low Pressure, with an associated Tropical Wave, is currently southeast of Jamaica and is generating unstable weather conditions over the island and its territorial waters. The System which is expected to be southwest of Jamaica on Tuesday, and move over the island on Wednesday, currently has a high chance of becoming a tropical cyclone during the next 48 hours The forecast is for occasionally heavy showers and thunderstorms to impact the island particularly during the afternoon on Monday. On Tuesday through Thursday expect an increase in rainfall with possible stormy weather conditions developing by Wednesday

Fishers and other marine interests, especially those on the cays and banks, are strongly advised to exercise caution as the system remains over the area. All interests are urged to pay special attention to subsequent news releases from the Meteorological Service

Thanks that from the met service.

Severe Weather Alert has been issued by the Jamaica Meteorological Service

NEWS RELEASE

October 22, 2012 at 6 a.m..

*** SEVERE WEATHER ALERT***

***LOW PRESSURE SOUTH OF JAMAICA LIKELY TO BECOME A TROPICAL STORM TOMORROW***

The Meteorological Service has issued a severe weather alert, effective until 5 a.m. tomorrow.

The area of Low Pressure is southeast of Jamaica and drifts slowly toward the west today and tonight. It is expected to develop into a Tropical Storm over the next day or so as it remains southwest of Jamaica. The system passes over the island Tuesday night as it moves toward the north northeast. Showers and thunderstorms are likely to affect the island which may be heavy at times while strong gusty winds are also likely over Jamaica, beginning tomorrow morning.

In view of this projection, it may be necessary to issue an evacuation notice for marine areas later today. All fishers on the cays and banks are, therefore, urged to hasten preparations with a view to evacuate at short notice, if required.

With weather conditions expected to deteriorate due to the passage of the developing system, marine operators are urged not to venture far from the mainland.

All interests are urged to pay special attention to subsequent news releases from the Meteorological Service.

I know this but I just want to pretend I'm dreaming. Jamaica is a really small target for this storm.

[cycloneye]

I know this but I just want to pretend I'm dreaming. Jamaica is a really small target for this storm.

Yeah, look at the forecast track. I imagine the authorities there starting preparations right?

Yes they have been the Office of Disaster Preparedness and Emergency Management has put it's emergency action plan into action. They have also asked all in flood prone and low lying areas to evacuate early. Honestly now that its this close I feel sick! I'll post preps observation and such as soon as I get a hold of myself. My apartment complex lies within reasonable distance of one of the waterways (The Sandy Gully) a TD a few years back broke the gully and took a portion of our back wall. To date it's not been fully repaired and I'm anxious that I may end up being in a danger zone. Because of this I've felt paralyzed by fear all day. On top of this my 4 yr old is sick with fever so I've been home and have had enough time to read everything online and drive myself nuts!

Be safe guys, hopefully won't be more than a rainy and breezy day, according to the HPC discussion our regions will be very wet early this week and rapid intensification could occur:

TROPICAL DISCUSSION - INTERNATIONAL DESKS
NWS HYDROMETEOROLOGICAL PREDICTION CENTER COLLEGE PARK MD
231 PM EDT MON OCT 22 2012

AT 15UTC TD EIGHTEEN CENTERED NEAR 13.5N 78.0W...WITH MAXIMUM
SUSTAINED WINDS OF 25KT AND CENTRAL PRESSURE OF 1003 HPA. THE
DEPRESSION IS MOVING SOUTHWEST AT 04KT.

DISCUSSION FROM OCT 22/00 UTC: THE NHC IS FORECASTING THE
DEPRESSION TO INITIALLY MEANDER OVER THE CENTRAL CARIBBEAN THEN
STARTS TO LIFT NORTH AS A DIGGING TROUGH ESTABLISHES TO THE
WEST...PROVIDING THE STEERING FLOW THAT WOULD ALLOW THIS SYSTEM TO
SLOWLY LIFT TOWARDS JAMAICA THROUGH 54-60 HRS. DUE TO THE SLOW
INITIAL MOTION...THEY EXPECT RAPID INTENSIFICATION OF THIS SYSTEM
DURING THE NEXT 18-24 HRS...AND COULD REACH HURRICANE INTENSITY
PRIOR TO MAKING LANDFALL OVER JAMAICA.

OUTER BAND CONVECTION IS LIKELY TO AFFECT JAMAICA-HAITIAN
PENINSULA THROUGH 36 HRS...WITH RAINFALL AMOUNTS OF 25-50MM/DAY
AND MAXIMA OF 75-150MM/DAY. BY 36-60 HRS...AS THE STORM NEARS
JAMAICA...THIS WILL INCREASE TO 75-125MM/DAY AND MAXIMA OF
250-300MM/DAY. ACTIVITY GRADUALLY BUILDS NORTH INTO WESTERN CUBA
THROUGH 60-84 HRS...WITH RAINFALL AMOUNTS OF 150-200MM/DAY AND
MAXIMA OF 350-500MM/DAY. FURTHERMORE...AS A LONG FETCH
SOUTH-SOUTHWESTERLY FLOW ESTABLISHES ACROSS THE CENTRAL-EASTERN
CARIBBEAN...MODEL GUIDANCE THEN SHOW PERSISTENT RAINFALL AMOUNTS
ACROSS SOUTHERN PORTIONS OF HISPANIOLA...WITH RAINFALL AMOUNTS OF
25-50MM/DAY AND MAXIMA OF 75-150MM/DAY. LOCALLY HIGHER AMOUNTS ARE
HIGHLY LIKELY ACROSS PENINSULA DE BARAHONA OVER THE DOMINICAN
REPUBLIC. STORM TOTAL AMOUNTS WITH THIS SYSTEM ARE LIKELY TO
EXCEED 500MM. THIS IS PARTICULARLY LIKELY ACROSS JAMAICA AND
EASTERN PORTIONS OF CUBA DUE TO STRONG TOPOGRAPHICAL/MECHANICAL
FORCING.

WEST OVER THE DOMAIN...A MID/UPPER LEVEL RIDGE IS FORECAST TO
DOMINATE THE FLOW OVER THE NEXT FEW DAYS...AS IT IS TO CENTER AT
250 HPA ON A CLOSED HIGH OVER COLIMA/NAYARIT OVER SOUTHWEST
MEXICO. THIS RIDGE...AS IT HOLDS...IS TO FAVOR A SUBSIDENCE CAP
ACROSS THE NORTHERN TO CENTRAL STATES OF MEXICO...WHERE IT IS TO
INHIBIT ORGANIZED DEEP CONVECTION DURING THE NEXT FEW DAYS.

AS THE UPPER LEVEL RIDGE HOLDS...IT IS TO THEN FAVOR THE SOUTHWARD
AMPLIFICATION OF A TROUGH ACROSS THE EASTERN GULF-YUCATAN TO THE
WESTERN CARIBBEAN. THE TROUGH WILL REACH MAXIMUM AMPLITUDE THROUGH
60-72 HRS. AS IT AMPLIFIES...THE TROUGH WILL FOCUS ITS SHORT WAVE
ENERGY ACROSS WESTERN CUBA AND THE NORTHWEST BAHAMAS...WITH STRONG
INFLOW OF CYCLONIC VORTICITY EXPECTED THROUGH 36-42 HRS. THIS WILL
ENHANCE CONVECTION...WITH ACTIVITY ACROSS CENTRAL-WESTERN CUBA
EARLY THIS CYCLE TO FAVOR RAINFALL AMOUNTS OF 10-15MM/DAY AND
MAXIMA OF 20-40MM...WHILE OVER THE CENTRAL/NORTHWEST BAHAMAS
EXPECTING ACCUMULATION OF 05-10MM/DAY AND MAXIMA OF 15-25MM. OTHER
ACTIVITY IS EXPECTED TO THE SOUTH ACROSS THE SOUTHERN STATES OF
MEXICO TO NORTHERN CENTRAL AMERICA...WITH TROUGH ALOFT TO ENHANCE
CONVECTION ACROSS SOUTHERN VERACRUZ-CAMPECHE-CHIAPAS IN SOUTHERN
MEXICO AND PORTIONS OF GUATEMALA...WITH RAINFALL AMOUNTS OF
05-10MM/DAY AND MAXIMA OF 15MM/DAY BY 36 HRS. ACROSS NORTHERN
HONDURAS EXPECTING RAINFALL AMOUNTS OF 15-20MM/DAY AND MAXIMA OF
25-50MM/DAY THROUGH 60-72 HRS.

SOME INTERACTION IS POSSIBLE FARTHER TO THE SOUTH...AS THE TROUGH
ALOFT INTERACTS WITH THE EASTERN PACIFIC ITCZ AS THE CONVERGENCE
ZONE MEANDERS ACROSS SOUTHERN CENTRAL AMERICA. INITIALLY EXPECTING
RAINFALL AMOUNTS OF 15-30MM/DAY AND MAXIMA OF 40-80MM ACROSS
SOUTHERN NICARAGUA-COSTA RICA TO PANAMA. THROUGH 48-60 HRS THIS IS
TO INCREASE TO 20-40MM/DAY AND MAXIMA OF 50-100MM/DAY. MODELS SHOW
MOST ACTIVE ON PACIFIC COASTAL PLAINS INTO THE CONTINENTAL DIVIDE.
FURTHERMORE...THE STORM...AS IT BECOMES BETTER ORGANIZED...IS
MODULATING THE ITCZ NORTH INTO THE SOUTHERN CARIBBEAN. THIS IS
ENHANCING CONVECTION ACROSS THE ABC ISLANDS...WHERE WE EXPECT
RAINFALL AMOUNTS OF 15-20MM/DAY AND MAXIMA OF 30-60MM/DAY. BUT AS
THE CYCLONE BECOMES BETTER ORGANIZED...CONVECTION IN THIS AREA IS
LIKELY TO WANE...WITH RAINFALL AMOUNTS OF 05-10MM/DAY AND MAXIMA
OF 15-30MM/DAY. ACROSS COLOMBIA TO NORTHWEST/CENTRAL VENEZUELA
EXPECTING ACCUMULATION OF 05-10MM/DAY AND MAXIMA OF 15-30MM/DAY.
ON THE PACIFIC PLAINS OF WESTERN COLOMBIA/EJE CAFETERO EXPECTING
ACCUMULATION OF 10-15MM/DAY AND MAXIMA OF 20-40MM.

UPPER TROUGH OVER THE WESTERN ATLANTIC CONTINUES TO PRESS AGAINST
CELL OF THE SUBEQUATORIAL RIDGE MEANDERING OVER THE CENTRAL/
EASTERN CARIBBEAN. THIS RIDGE IS VENTING DEEP CONVECTION ACROSS
THE CENTRAL CARIBBEAN IN ASSOCIATION WITH TD-EIGHTEEN. ALSO AT
UPPER LEVELS...A TUTT REMAINS EAST OF THE ISLAND CHAIN...WITH
BROAD CIRCULATION NOW EXPANDING BETWEEN 62W-40W AS IT CENTERS ON A
LOW NEAR 22N 49W. CONVECTION HAS STARTED TO ORGANIZE AROUND THIS
SYSTEM...AND COULD EVOLVE INTO A SUBTROPICAL CYCLONE AS INDICATED
BY THE NHC. THE EASTERN CARIBBEAN ISLES LIE ON THE CONVERGENT SIDE
OF THE TROUGH/RIDGE PAIR. THIS IS INHIBITING ORGANIZED CONVECTION
ACROSS THE LESSER ANTILLES TO NORTHEAST VENEZUELA. THE CELL OF THE
SUBEQUATORIAL RIDGE IS FORECAST TO HOLD RELATIVELY FLAT OVER THE
NEXT 24-36 HRS. AXIS IS TO THEN BUILD NORTH INTO THE WESTERN
ATLANTIC AS A HIGH AMPLITUDE/LONG WAVE TROUGH ESTABLISHES FARTHER
TO THE WEST.

AT LOW/MID LEVELS...EASTERLY TRADES ARE TO INITIALLY
DOMINATE...WITH WINDS TO GENERALLY REMAIN BELOW 10-15KT. DIURNAL
CONVECTION WILL CONCENTRATE ACROSS NORTHERN PORTIONS OF PUERTO
RICO TO EASTERN HISPANIOLA...WITH HIGH RESOLUTION MODEL GUIDANCE
SHOWING MAXIMA OF 15-25MM. MOST ACTIVE IS EXPECTED THIS
AFTERNOON...THEN BECOME WIDELY ISOLATED ON TUESDAY AS CAP
INVERSION IS FORECAST TO STRENGTHEN ACROSS THE FORECAST AREA.
THROUGH 60-72 HRS...AS THE CYCLONE TO THE WEST STRENGTHENS...WINDS
ARE TO QUICKLY VEER TO THE SOUTH-SOUTHEAST. GFS INITIALLY SHOWS
PWAT OF 35-40MM. BUT...AS THE WINDS SHIFT TO THE SOUTH...IT THEN
SHOWS A RAPID SURGE THROUGH WEDNESDAY MORNING. DURING THAT PERIOD
PWAT INCREASES TO 50-60MM. ALTHOUGH MOISTURE BECOMES PLENTIFUL...
MODELS SHOW LITTLE TO NO CONVECTION ACROSS PUERTO RICO/USVI-LESSER
ANTILLES. LOOKS LIKE THE INCREASE IN MOISTURE IS TO MANIFEST AS
HIGH CI/CS ACROSS THE FORECAST AREA...BLOCKING SOLAR RADIATION AND
INHIBITING THE SEA BREEZE CYCLE.
