These are the temperatures registered yesterday in the region:
-Warmer than normal lows in Belize, Honduras, Costa Rica and Panama. Near normal lows in El Salvador and Nicaragua. Cooler than normal lows in Guatemala.
-Nicaragua, Costa Rica and Panam experienced cooler than normal highs, in the rest of the region the highs were near normal for this time of year.

438 AM AST WED DEC 21 2011

.SYNOPSIS...THE WEAK FRONTAL BOUNDARY/SHEAR LINE NOW OVER THE
NORTHERN LEEWARDS AND EXTENDING ACROSS SAINT CROIX THIS MORNING...IS
EXPECTED TO CONTINUE TO DRIFT FURTHER SOUTH INTO THE CARIBBEAN
WATERS TODAY WHILE DISSIPATING. LATEST SATELLITE IMAGERY ALONG WITH
GFS MODEL GUIDANCE INITIALIZED WELL AND CONTINUE TO SUGGEST THAT A
BROAD MID TO UPPER LEVEL HIGH PRESSURE RIDGE EXTENDING NORTHWARDS
ACROSS THE LOCAL AREA FROM THE CARIBBEAN BASIN...WILL REMAIN IN
PLACE THROUGH THEN END OF THE WEEK. THIS IS SUPPORTED BY SURFACE
HIGH PRESSURE WHICH WILL BUILD AND SPREAD EASTWARDS ACROSS THE
WEST AND SOUTHWEST ATLANTIC THROUGH THE END OF THE WEEK. THIS
OVERALL PATTERN WILL MAINTAIN A STRONG SUBSIDENCE CAP ACROSS THE
REGION FOR THE NEXT SEVERAL DAYS. HOWEVER THE INDUCED TIGHT SURFACE
PRESSURE GRADIENT ACROSS THE REGION WILL MAINTAIN A STRONG EAST
NORTHEAST TRADE WINDS AND THEREFORE LEAD TO BREEZY CONDITIONS
ACROSS THE LOCAL ISLANDS AND SURROUNDING WATERS AT LEAST THROUGH
THURSDAY.

&&

.DISCUSSION...ABOVE MENTIONED SURFACE HIGH PRESSURE WILL REESTABLISH
ITSELF AND REMAIN ANCHORED ACROSS THE WEST AND CENTRAL ATLANTIC OVER
THE NEXT FEW DAYS. THIS IN TURN WILL CAUSE AN INCREASE IN THE EAST
NORTHEAST TRADE WIND FLOW OVER THE FORECAST AREA. THE STRONG NORTHEAST
FLOW WILL INDUCE LOW LEVEL CONVERGENCE AND THEREFORE CONTINUE TO BRING
SURGES OF LOW LEVEL MOISTURE ACROSS THE REGION OVER THE NEXT COUPLE
OF DAYS. THIS WILL RESULT IN PERIODS OF QUICK PASSING SHOWERS ALONG
WITH LOW LEVEL CLOUDINESS WHICH WILL FIRST AFFECT THE NORTH AND
EAST COASTAL AREAS OF THE ISLANDS DURING THE LATE EVENING AND
EARLY MORNING HOURS. SOME OF THE ACTIVITY MAY THEN SPREAD FURTHER
INLAND DURING THE LATE MORNING HOURS. DURING THE REST OF THE
AFTERNOON HOURS...EXPECT DECREASING CLOUDINESS WITH MOSTLY AREAS
OF ISOLATED SHOWERS AND OVERALL FAIR WEATHER SKIES...ALONG WITH
BREEZY CONDITIONS. EXPECT THIS WEATHER PATTERN TO PREVAIL ACROSS
THE FORECAST AREA THROUGH THE WORK WEEK AND INTO THE UPCOMING
WEEKEND. NO SIGNIFICANT WEATHER FEATURE IN SIGHT AT THIS TIME WITH
THE TYPICAL SEASONAL WEATHER REGIME EXPECTED FOR THE NEXT SEVERAL
DAYS.

THE OVERALL SYNOPTIC PATTERN AND STRONG TRADE WINDS ARE HELPING TO
CREATE ROUGH AND HAZARDOUS SEAS...ALONG WITH DANGEROUS SURF
CONDITIONS. THEREFORE A HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL
AT LEAST THURSDAY EVENING. SMALL CRAFT ADVISORIES REMAIN IN EFFECT
FOR MOST OF THE LOCAL WATERS AND PASSAGES. PLEASE REFER TO LATEST
MARINE WEATHER MESSAGES/BULLETINS.

&&

.AVIATION...MAINLY VFR CONDITIONS ARE EXPECTED ACROSS THE LOCAL
ISLANDS AND AT ALL TAF SITES THROUGH THE NEXT 24 HOURS. HOWEVER...
CLOUDINESS WITH BRIEF PERIODS OF MVFR CONDITIONS IN SCATTERED
PASSING SHOWERS...WILL CONTINUE THROUGH THE REST OF THE MORNING...
MAINLY OVER TASK AND TIST. IN ADDITION...SURFACE WIND GUSTS TO 25
KNOTS ARE EXPECTED...ESPECIALLY IN AND NEAR SHOWERS AND OVER COASTAL
AREAS AND HIGHER ELEVATIONS.

Good morning

The cold front is here. All anyone is talking about is how cold they are. LOL
We should have to experience some of those low temps macrocane posts..then we would know what cold really is I guess.
The temp this morning a 6:00 AM was 73 degrees with wind from ENE at 15 MPH. We had some light rain showers.

Now the temperature has gone up to about 78 degrees but I am still cold.
I have on socks, long pants, and long sleeves
It is overcast and windy. Wind now is ENE around 18 MPH.

Again this year the sea has decided to kill!! . What a nightmare

The missing fisherman found dead

B.C. France-Antilles Guadeloupe21.12.2011
http://www.guadeloupe.franceantilles.fr ... 151099.php

The sports teacher, missing since Sunday after be party caught in the area of the great lookout to Anse-Bertrand, was found without life. At the end of a little over 48 hours of research, are air assets of the mounted police who conducted the macabre discovered yesterday late morning. "From the air, a body floating at the foot of the cliffs has unfortunately been overview", has confirmed in the evening the captain Frantz, Commander of the gendarmerie of the mould company.

MARITIME CONDITIONS DIFFICULT

The configuration of the premises and especially degraded marine conditions have made operations to retrieve the remains difficult. It is only in mid-afternoon these searchers in the mounted police helicopter, assisted in their task by the specialists of the boating brigade of Pointe-à-Pitre, are finally managed to get the victim to the water. Not without having benefited from a changing current.

"Everything suggests that the victim, after have skidded or have been swept away by a blade, found herself taking under the rock.". "This is the most likely hypothesis", suggested investigators to explain the tragedy. Back on shore, the body was formally identified by the family of Professor of sport, without so they be returned. The public prosecutor pointois who ordered that he be examined by forensic doctors.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1231 PM AST THU DEC 22 2011

.UPDATE...LIGHT PASSING SHOWERS HAVE BEEN OBSERVED OVER THE
EASTERN HALF OF PUERTO RICO...ONLY TRACE AMOUNTS OF RAIN HAVE BEEN
OBSERVED AT THE SAN JUAN AIRPORT SINCE THE 0.01 INCHES THAT WERE
OBSERVED EARLY IN THE MORNING. SAME GOES FOR THE USVI...ONLY TRACE
AMOUNTS OBSERVED WITH A POSSIBLE 0.01 INCH OF RAIN VERY EARLY IN
THE MORNING.

THE FORECAST WAS ADJUSTED SLIGHTLY AS THE MEASURABLE
PRECIPITATION IS LIMITED TO ISOLATED AREAS AND THE LIGHT SHOWERS
ARE MOVING VERY QUICKLY. THEREFORE THE FORECAST WAS ADJUSTED TO
ISOLATED SHOWERS WITH LITTLE ACCUMULATION POSSIBLE. THIS GENERAL
PATTERN IS EXPECTED THROUGH THE REST OF THE DAY. QUICK PASSING
LIGHT SHOWERS WITH VARIABLE CLOUDINESS ACROSS THE NORTHERN AND
EASTERN SECTIONS OF PUERTO RICO AS WELL AS THE USVI. THE
SOUTHWESTERN QUADRANT OF PUERTO RICO IS EXPECTED TO REMAIN FAIRLY DRY.

MARINE CONDITIONS CONTINUE TO BE HAZARDOUS. THEREFORE THE HIGH
SURF AND SMALL CRAFT ADVISORIES ARE STILL IN EFFECT.
