[cycloneye]

Happy Easter to all the friends in the Caribbean and in Central America.

[Macrocane]

Thank you very much cycloneye!!! The Holy Week is a very important holiday in Central America, a great time full of traditions, delicious food and family meetings. Happy Easter to you too in the Caribbean

Gusty, those rainfall amounts are very high, I guess is enough to reach normal levels for this time of the year, hopefully you don't get more than you need.

Back green code in Guadeloupe after a pretty rainy event. In terms of rainfall Meteo-France Guadeloupe reported in some localities :149mm at Anse-Bertrand, 131 mm at Baie-Mahault (where i'm living) , 90 mm at les Abymes Raizet and till Jusqu'à 400 mm in 48h at Capesterre and our volcano Soufrière. On the opposite, the west tip of the island has been relatively spared as other
localities like Pointe des Châteaux, les Saintes and Marie-Galante with values near 10 millimeters.

As a conclusion, Guadeloupe have been blessed on this period These rains came at the right time and have stopped partially (some areas have not been well showed!) the severe drought who was affecting the whole island. I don't know if the others neighbours get some from this, let's hope so...

[Gustywind]

Thank you very much cycloneye!!! The Holy Week is a very important holiday in Central America, a great time full of traditions, delicious food and family meetings. Happy Easter to you too in the Caribbean

Gusty, those rainfall amounts are very high, I guess is enough to reach normal levels for this time of the year, hopefully you don't get more than you need.

Happy easter to you Macrocane and in Central America. Have fun, enjoy it! For most the localities we can say YES, but unhopefully these amounts are not so high in some localities ( rainfall near or less than 10 millimeters). The showers were irregulars especially on the west side of the island, whereas that was a very pretty wet episode, something good for us, we were blessed for sure compared to others islands .

[msbee]

Happy Easter Everyone!
Enjoy the holidays!





We received some welcome rain yesterday.
Today is just cloudy so far.
Today and tomorrow are big beach days here on the island.

[tropicana]

Happy Easter to all!

UPDATE Fri Mar 29/13 8pmET A ridge of high pressure is keeping stable weather across most of the islands of the Eastern Caribbean. An exception (there usually always is) is portions of the Leeward Islands , Virgin Islands and Puerto Rico where moisture associated with a frontal boundary is producing occasional cloudiness and showers, with gusty winds. Reports of 50 to 100 mm of rain ( 2 to 4 inches) from parts of Northern and NE Puerto Rico..has sent some rivers over their banks and caused flashflooding today. St Thomas VI reported 8mm today, and through 2pm Friday, 7mm of rain fell at Melville Hall Dominica and 4mm at Le Raizet Guadeloupe...while 7mm of rain recorded at VC Bird Antigua. But to the SW of St Johns, at Jolly Harbour, Antigua ..reliable reports of in excess of 50mm ( 2 inches) reported this afternoon. The moon is 91% illuminated tonight and will be rising across the islands within the hour.


UPDATE Sat Mar 30/13 745pmET Generally sunny and hazy weather conditions prevailed across the Windward Islands, Barbados, Trinidad and Tobago... as well as the Southern Leeward Islands. Across the Northern Leeward Islands, skies were overcast with frequent periods or rain and showers thanks to a frontal boundary/ trough . Some prolific rainfall totals were reported for the 2nd straight day, with VC Bird International Airport in Antigua picking up 68 mm of rain in the 18 hours ending at 2pmET Saturday ..thats just shy of 3 inches of rain (brings the March 2013 rain total to 98mm) ..but not the only island to see incessant rainfall today. LeRaizet Guadeloupe saw 90mm of rain , thats just shy of 4 inches in the same 18 hour period. At Golden Rock St Kitts , 9mm of rain fell. Temperatures were kept unseasonably cool thanks to the rain and cloud cover, the high temp at Golden Rock St Kitts was just 26.1C 79F and even a cooler 25.1C 77F at VC Bird Antigua. Nearby Anguilla reported no rainfall at all at West End. San Juan PR reported just 2.8mm of rain today. Juliana Airport St Maarten reported 4mm and Roosevelt AIrport St Eustatius 3mm. On the other end of the spectrum, the warmest temperature in the region was at P{iarco Airport Trinidad with 33.0C 91F . This trough system affecting the Leewards is forecast to weaken with time and move north .. retrograding back up to the extreme Northern Leewards, the Virgin Islands and Puerto Rico region ... but a strong HIGH pressure will move from North of the Bahamas to the Western Atlantic and bring strong ridging across the island chain, so improving weather is forecast for the Leewards..and a continuation of hot, dry and windy weather elsewhere. The waning gibbous moon is 84% full tonight and will rise tonight around 9:30pm local time across the Eastern Caribbean .

[cycloneye]

Good afternoon. After this couple of days that has brought plenty of rain to PR,things dry out and it looks like most of the week will be mainly dry with isolated showers.

UPDATE Sun Mar 31/13 730pmET A robust high pressure 1025mb will gradually move to the NE of the island chain this week and strengthen even more to at least 1030mb ... this will in turn provide strong ridging at all levels of the atmosphere , bring glorious sunshine through the week for the islands. The high pressure has strengthened the wind field as well, and winds are expected to be brisk and gusty this week, at times gusting between 25 to 35mph. This will makes seas choppy and rough, especially out on open waters...with a prevailing wind direction from the East, so east coasts of the islands could take a beating, and mariners should exercise caution.
That wind along with the hot and dry weather could exacerbate any outdoor fires , and it is inadvisable to light any such fires for burning of refuse this week in particular.

The wind has aided in bringing in spots of clouds and moisture across some of the islands today, especially across the Central and Northern Windward Islands. Rainfall today meausred 2mm at LeLamentin Martinique, 2mm at Crown Point Tobago, 4mm at Arnos Vale St Vincent, 8mm at Hewannora St Lucia and 1mm at Grantley Adams Barbados. The clouds and showers affecting the Northern Leewards moved further north and affected Puerto Rico and the Virgin Islands today. In fact, showers were quite numerous over portions of eastern sections of Puerto Rico, where some individual rain gauges picked up over 25mm of rain . At San Juan PR 8mm of rain fell, 8mm at St Thomas VI, but the most excessive rainfall was over St Croix VI where the airport picked up at least 30mm of much needed rainfall. The weather will improve greatly this week in this region as well.

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE SAN JUAN PR
555 AM AST TUE APR 2 2013

.SYNOPSIS... SURFACE HIGH PRESSURE NORTH OF THE AREA WILL CONTINUE
TO SHIFT FURTHER EAST INTO THE CENTRAL ATLANTIC THROUGH WEDNESDAY.
THEREAFTER IT WILL MERGE AND BECOME REINFORCED BY ANOTHER AREA OF
HIGH PRESSURE TRAILING A COLD FRONT WHICH WAS NOW ENTERING THE WESTERN
ATLANTIC. IN THE MEANTIME THE SURFACE HIGH PRESSURE WILL MAINTAIN LIGHT
TO MODERATE EAST TO SOUTHEAST TRADE WIND FLOW ACROSS THE REGION AT
LEAST UNTIL WEDNESDAY. EXPECT THE LOCAL PRESSURE GRADIENT TO
CONTINUE TO LOOSEN TODAY AND WEDNESDAY IN RESPONSE TO THE ATLANTIC
HIGH SHIFTING EAST. THIS HOWEVER WILL BE SHORT LIVED AS THE
PREVAILING EASTERLIES WILL SLIGHTLY INCREASE ONCE AGAIN BY
THURSDAY AND FRIDAY AS THE SURFACE HIGH REESTABLISHED NORTH OF THE
AREA. MID TO UPPER LEVEL RIDGE WILL GRADUALLY BUILD ACROSS THE
REGION THROUGH THE END OF THE WEEK AND THUS MAINTAIN AN OVERALL
SUBSIDENT AIR MASS WITH A PREVAILING WESTERLY WIND FLOW ALOFT.

&&

.DISCUSSION...FEW PASSING SHOWERS CONTINUED ACROSS THE LOCAL
OFFSHORE WATERS OVERNIGHT MAINLY ALONG AN OLD AND DISSIPATING
FRONTAL BOUNDARY WHICH HAS NOW LIFTED NORTH OF THE ISLANDS. THE
EAST TO SOUTHEAST TRADE WINDS WILL PREVAIL THROUGH THE END OF THE
WEEK HOWEVER THE SLIGHT WEAKENING OF THE LOCAL PRESSURE GRADIENT
WILL LEAD TO LOCAL SEA BREEZE ENHANCEMENT IN SOME AREAS. THIS WILL
ALLOW FOR LIMITED AFTERNOON SHOWER DEVELOPMENT TODAY AND ON WEDNESDAY...
MAINLY ACROSS THE WEST AND NORTHWEST INTERIOR SECTIONS OF PUERTO
RICO. LIMITED OR NO SHOWER ACTIVITY CAN BE EXPECTED OVER THE VIRGIN
ISLANDS TODAY AND WEDNESDAY.

BY THE END OF THE WEEK AND INTO THE UPCOMING WEEKEND...THE DOMINANT
EASTERLIES WILL HELP TRANSPORT OCCASIONAL PATCHES OF MOISTURE ACROSS
THE ISLANDS AND SURROUNDING WATERS. BASED ON LATEST MODEL GUIDANCE
AND RECENT SATELLITE IMAGERY...EXPECT THIS MOISTURE INFLUX AND SHOWER
ACTIVITY TO BE SHALLOW AND OF SHORT DURATION. AS A RESULT...EXPECT ONLY
PERIODS OF PASSING SHOWERS WITH THE BEST CHANCE FOR ENHANCED SHOWERS
DURING THE EARLY MORNING AND AFTERNOON HOURS ACROSS PARTS OF THE
ISLANDS BY FRIDAY AND CONTINUING OVER THE UPCOMING WEEKEND.

&&

.AVIATION...MAINLY VFR CONDITIONS EXPECTED ACROSS THE LOCAL FLYING
AREA THROUGH THE FORECAST PERIOD. HOWEVER...FEW PASSING SHRA WILL
MOVE NORTHWESTWARD ACROSS THE LOCAL TAF SITES THIS MORNING...BUT
MAINLY AFFECTING THE LOCAL WATERS AND THE WINDWARD AREAS. TJSJ
02/00Z SOUNDING INDICATED AND EAST SOUTHEAST WIND FLOW OF 10-30
KNOTS FROM THE SURFACE TO AROUND FL120...BECOMING WEST SOUTHWEST AND
STRONGER ALOFT. SOUTHEAST SURFACE WINDS ARE EXPECTED TO INCREASE
AFTER 02/12Z.

&&

.MARINE...LOCAL SEAS OFFSHORE HAVE SUBSIDED AND NOW RANGE BETWEEN
5 TO 7 FEET AT BOTH BUOY 41043 AND 41053...WITH STILL SLIGHT CHOP
DUE TO MODERATE TO LOCALLY FRESH TRADE WINDS. SMALL CRAFT
OPERATORS SHOULD STILL EXERCISE CAUTION ACROSS THE NORTHERN
ATLANTIC WATERS TODAY. LATEST MARINE MODEL GUIDANCE CONTINUE TO
SUGGEST A STEADY DECREASE IN LOCAL SEAS OVER THE NEXT FEW DAYS.
