CONTINUE TRANSPORTING MOISTURE AND SCATTERED SHOWERS ACROSS THE
REGION THROUGH AT LEAST TUESDAY. LARGE...LONG PERIOD NORTHWEST

.DISCUSSION...WATER VAPOR IMAGERY REVEALS A BROAD ANTICYCLONIC
CIRCULATION IN RESPONSE WITH A DEEP LAYER RIDGE EXTENDING FROM THE
EASTERN CARIBBEAN TO THE TROPICAL ATLANTIC. THE ASSOCIATED SURFACE
HIGH PRESSURE IS INDUCING A SOUTH TO SOUTHWEST WIND FLOW ACROSS
THE NORTHEAST CARIBBEAN. AS THE SURFACE HIGH PRESSURE MOVES TO THE
NORTH...WINDS WILL GRADUALLY BACK FROM THE EAST TO NORTHEAST BY
MIDWEEK. FROM WEDNESDAY THROUGH SUNDAY...OPERATIONAL MODELS SUGGEST
A DRYING TREND AS MID LEVEL RIDGE STRENGTHENS THE CAP ACROSS THE
FORECAST AREA...LIMITING THE SHOWER ACTIVITY ACROSS PUERTO RICO.
THE MAIN CONCERN FOR PUERTO RICO AND NORTHERN U.S. VIRGIN ISLANDS
IS THE LARGE NORTHWEST SWELLS ASSOCIATED WITH HURRICANE SANDY THAT
ARE AFFECTING THE THE LOCAL ATLANTIC WATERS AND CARIBBEAN PASSAGES.
AS A RESULT...A HIGH SURF WARNING AND A COASTAL FLOOD ADVISORY
CONTINUES IN EFFECT THROUGH NOON AST TUESDAY FOR THE WEST THROUGH

AND SAINT JOHN. A HIGH SURF ADVISORY IS IN EFFECT FROM NOON AST
TUESDAY THROUGH 6 AM AST WEDNESDAY MORNING.

ISLANDS AND AT ALL TAF SITES DURING THE 24 HOURS. HOWEVER...BRIEF
MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURATIONS ARE POSSIBLE IN

West Indies: presumed missing at sea, they return to the port safely
AFP 29.10.2012
http://www.microsofttranslator.com/bv.a ... 192120.php
Six or seven French are missing at sea between Martinique and Dominica since Sunday evening, learned Monday AFP the Ministry of transportation, which said that the swell was high after the passage of Hurricane Sandy. -(Naval Research Laboratory/AFP)
Six French which feared the disappearance in a sea agitated between Dominica and Martinique returned Monday safely to their home port in the French Department, without suspecting the exposures fright and the means deployed to search for them.
Research had been undertaken Monday after that the companion of one of the men was concerned do not see return Sunday night. The sea was still "dangerous" and the area of Martinique placed in yellow vigilance Monday, according to weather France, after the passage of Hurricane Sandy.
The Group of thirty-somethings, two women and four men, were gone Friday attend a music festival in a stadium in Roseau, the capital of Dominica, anglophone island located about 30 kilometres from Martinique.
They had used a large zodiac belonging to one of them to get to the 16th edition of the World Creole Music Festival, where should such occur Damian Marley, a son of Bob Marley, and figures of zouk, as Tanya Saint Val or group Zouk Machine, very popular in the West Indies.
The festival was held during three nights, from Friday evening to Sunday evening included, according to its website. It is at this stage that the misunderstanding could be completed.
Cosmy to Trinity Harbour, on the Atlantic coast of Martinique (East), where the Zodiac has his ring, a fisherman had to return the Group of friends. "They were particularly worried, they said that they were to arrive Monday in the day", this fisherman, Philippe Eraclide, told an AFP correspondent.
In fact, "they left Dominica at 11: 00 local (16 H 00 in Paris) and arrived without encumbrances, it has had no problem", told AFP the Antilles Guyane (operational regional Centre for monitoring and rescue) Cross who came to speak on the phone with them shortly after 14 H 00 (19 H 00 in Paris).
In the meantime, it is the general mobilization: information from the Department of transportation showing French "disappeared at sea", sending an aircraft type Cessna and customs of a helicopter of civil safety above the canal along the Martinique and Dominica. Alert messages had been disseminated to vessels passing through the area.
During the few hours of uncertainty, it was not possible to know whether the six people - fallen down to cell phone battery - had left Dominica. The Cross also remained in contact with the authorities of the former nearby British possession to try to clarify this point.
Hurricane Sandy, who is raging in the Atlantic and made dozens of dead in the Caribbean, was demoted to storm tropical Saturday. It goes back to the North, along the coast of the United States where the State of emergency was declared.

If things are improving and begin even to shine in the Lesser Antilles after Sandy... Haiti continue to be in a very worrying situation 
.
HAITI
A very alarming situation after Sandy
France-Antilles Guadeloupe 02.11.2012
http://www.microsofttranslator.com/bv.a ... 192512.php
A week after the passage of Sandy, the Government is struggling to prepare an assessment of the damage caused by the hurricane in a country that always licks the wounds of the devastating 2010 earthquake.
'' The balance sheet is heavy, roads and bridges have not withstood, the economy was hard hit. "More than 200 000 people are affected and the food security of the country is now problematic," stressed the Government by Tuesday night the State of emergency throughout the country.
According to the latest report available to the Civil Protection Directorate, Sandy has made 51 dead and 20 missing in the country, while thousands of people were still in temporary shelters.
Together with the Haitian authorities, international experts continue to assess the damage caused by bad weather in difficult conditions: some regions were still inaccessible in midweek.
"RISING PRICES OF COMMODITIES.
"What worries the most is food security, which will be the most serious consequence of the passing of Sandy ', says Johan Pelemen of the Office of the United Nations for Humanitarian Affairs (OCHA).
According to the UN official, the weather had a "disastrous impact" on agriculture as they arrived at the moment where the crops were underway. A first estimate in the agricultural sector reported losses of $ 104 million, according to Garry Mathieu, Director of the national Council for food security (CNSA). According to him, the departments of the South and Grand ' Anse, most affected, represent the granaries of Haiti.
"In the coming days, there will be a reduction of local food availability, which will lead to an increase in commodity prices", he says.
After the passage of the hurricane, the Haitian Government announced that approximately $ 8 million were made available in the affected areas.
A CALL FOR INTERNATIONAL HELP
«Donors must not turn elsewhere and forget about Haiti that still humanitarian needs related to the earthquake, to which were added the consequences of the hurricane Sandy», said Mr. Pelemen.
"He will have to appeal to international aid, but for now we have water and food that were pre-positioned to manage emergencies", added.
Internationally, this new disaster that struck Haiti has gone relatively unnoticed compared to media coverage of Sandy in the United States, and especially in New York. However, the Venezuela was offered a boat and a cargo of humanitarian aid plane.
Passage in Haiti as an Ambassador of good will of UNDP, crownprince Haakon de Norway also visited flooded areas in the South, noting that families have been hit hard.
"I hope that the international partners of Haiti will help the country to recover from the impact of Sandy", he confided.
-A country forgotten by the media
The cameras around the world remain turn on the ravages of Sandy in New York, object of all the fantasies and media capital, contrast with the journalistic treatment minima of the 50 dead in Haiti left in the wake of the hurricane.
The ravages of Sandy in Haiti have gone relatively unnoticed. The International Herald Tribune devoted Wednesday its an and several blogs at United States, against a skinny column to the situation of Haiti, written in Mexico City.
Professionals and media observers put forward including slow communication around the situation in Haiti.
"Indeed, the hurricane has claimed more lives in Haiti (...), but the authorities came with these several numbers s day s after Sandy." "Fault of ways probably they failed to inform in time", said journalist on-site, adding that the Government has declared a State of emergency only Tuesday, a week after the passage of Sandy.
Moreover, if number of journalists were already at the United States at the time of the passing of Sandy, notably to cover the U.S. presidential campaign, few were present in Haiti.
