I hope that this rain event does not cause many problems tonight and tommorow but lets see what happens in the comming hours to see if I can get away from the PC as planned.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN JUAN PR
851 PM AST THU DEC 24 2009

.UPDATE...LINE SO FAR HAS MAINTAINED STRENGTH AND INTEGRITY WITH
SOME ELECTRICAL ACTIVITY STRETCHING FROM 10 NM NORTHWEST OF
AGUADILLA TO WELL OUT INTO THE MONA CHANNEL WEST OF CABO ROJO. BUT
HEAVY SHOWER ACTIVITY HAS ALSO CONTINUED FROM GUAYANILLA AND JUANA
DIAZ TO SAN LORENZO AND FAJARDO. SUFFICIENT RAIN IS ON THE WAY
SUCH THAT A FLASH FLOOD WARNING HAS BEEN DEEMED PRUDENT FOR
NORTHEAST PUERTO RICO. AND WILL ISSUE A FLASH FLOOD WATCH BUT HAVE
NOT DECIDED HOW MUCH OF PUERTO RICO IT WILL INVOLVE.

&&

.DISCUSSION...WRF MODEL STILL DOING BEST. NAM HAS NOT EVEN GOTTEN THE
LINE`S POSITION RIGHT AND SO MUST COMPLETELY DISCOUNT IT. GFS DOING
OK WITH LOW PRESSURE FORMING OR DEEPENING NORTHEAST OF LOCAL AREA
DURING NEXT 24 HOURS THEN DRIFTING EAST NORTHEAST. WRF HAD
CONSIDERABLE RAIN REMAINING ON THE NORTHEAST COAST FOR MUCH OF THE
NIGHT. EXPECT SIGNIFICANT RAIN AMOUNTS BUT...AT LEAST FOR THE TIME
BEING...HEAVY RAIN AND FLOODING SHOULD BE VERY LOCALIZED IN THE
EAST. STILL WATCHING TO SEE HOW WELL THE WRF WILL VERIFY. ITS
FORECAST IS UNIQUE AND CALLS FOR THE LINE TO SPLIT TO THE NORTH AND
SOUTH SOUTHEAST. ITS SOLUTION KEEPS THE RAIN OFF OF WESTERN PUERTO
RICO EXCEPT FOR AMOUNTS LESS THAN .25 INCHES. THIS SEEMS
REASONABLE FOR THE MOMENT AND THUNDERSTORMS HAVE REMAINED
OFFSHORE...BUT THUNDERSTORMS SUGGEST IT MAY BE ABLE TO SPREAD RAIN
GREATER THAN FORECAST...SO WILL MONITOR CLOSELY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
702 AM AST FRI DEC 25 2009

.SYNOPSIS...HIGH PRESSURE SYSTEM ACROSS THE CENTRAL ATLANTIC
EXTENDS SOUTHWESTWARD TO THE NORTHEASTERN CARIBBEAN. ANOTHER HIGH
PRESSURE SYSTEM ACROSS THE NORTHWEST ATLANTIC EXTENDS SOUTHWARD TO
JUST NORTH OF THE LOCAL AREA. THEREFORE...THE LOCAL ISLANDS ARE IN
BETWEEN THESE TWO HIGHS. THIS CREATES A LIGHT WIND SITUATION AT
THE SURFACE.

UPPER LEVEL SHORT WAVE IS EXPECTED TO MOVE ACROSS THE AREA LATER
TONIGHT INTO SATURDAY MORNING...WHILE AN UPPER LEVEL HIGH BUILDS
OVER THE SOUTHWESTERN CARIBBEAN AND SPREADS EASTWARD. THIS WILL
CREATE SUBSIDENCE AND LIMIT CONVECTION OVER OUR AREA.

&&

.DISCUSSION...SHOWERS AND THUNDERSTORMS HAVE DIMINISHED ACROSS
MUCH OF THE LOCAL AREA THIS MORNING. HOWEVER...A LOT OF PLACES
OVER THE EASTERN HALF OF PUERTO RICO REMAIN UNDER WATER DUE TO THE
TORRENTIAL RAINS THAT FELL OVER THE CENTRAL INTERIOR AND EASTERN
INTERIOR SECTIONS OF PUERTO RICO.

INSTABILITY REMAINS HIGH ACROSS THE DISCUSSION AREA FOR ANOTHER
BURST OF SHOWERS AND THUNDERSTORMS MAINLY ACROSS THE SOUTHEAST
PORTION OF THE ISLAND AND THE U.S. VIRGIN ISLANDS.

WEATHER CONDITIONS SHOULD BEGIN TO SIGNIFICANTLY IMPROVE DURING
THE SECOND HALF OF THE UPCOMING WEEKEND.


&&

.AVIATION...VFR CONDITIONS TO PREVAIL ACROSS THE LOCAL TAF SITES
WITH BRIEFLY MVFR AN EVEN IFR FOR SAINT THOMAS...AND SAINT CROIX
AIRPORTS FROM 12Z TO 16Z.


&&

.MARINE...LARGE AND LONG PERIOD NORTHEASTERLY SWELLS FOR THE UPCOMING DAYS
ARE ANTICIPATED TO CREATE HAZARDOUS MARINE CONDITIONS ACROSS THE
AREA WATERS INCLUDING THE CARIBBEAN PASSAGES. STAY TUNED.

[msbee]

yes, it's a wet Christmas in St Maarten. It's raining now heavily and thundering.
The wind is blowing hard.
I heard Culebra and Vieques got over 4 inches of rain last night.
Looks like that rain event has arrived here.

nevertheless, we won't let it dampen our Christmas cheer.
Enjoy the day everyone!
Don't eat too much!

[Macrocane]

Merry christmas! I hope you have enjoyed the christmas eve and enjoy the christmas day. As I told everytime that there is a cold front event in Centralamerica I post the observations on the winter weather forum, this time have written the data for Belize, Guatemala, San Salvador, Tegucigalpa and Managua. Here is the link:

Centralamerican Cold Surges

By the way, we had a cold morning as the temperature was 15 °C (59°F) It was unexpected for me because currently there are no strong cold fronts, at this time it has warmed up and we have 27 °C (80.6 °C).

[cycloneye]

The sun is out here making the day to be explendid for Christmas. All is going great with the family opening gifts and eating Lechon with arroz con gandules and pasteles.

Here is the updated discussion.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1224 PM AST FRI DEC 25 2009

.UPDATE...THE DOPPLER RADAR AND SATELLITES IMAGES LATE IN THE
MORNING SHOWED SCATTERED SHOWERS AND A FEW THUNDERSTORMS ACROSS THE
CARIBBEAN OFFSHORE COASTAL WATERS...WITH MINIMAL PRECIPITATION
ELSEWHERE ACROSS THE FA. ALL WATCHES/WARNING WERE CANCELLED AS A
RELATIVELY DRY AIR MASS MOVED ACROSS THE REGION FROM THE
WEST...LIMITING THE SHOWER ACTIVITY ACROSS THE LOCAL ISLANDS. THE
SURFACE LOW PRESSURE SYSTEM ACROSS THE NORTHEAST CARIBBEAN WILL
CONTINUE TO MOVE EASTWARD AND AWAY FROM THE LOCAL ISLANDS THIS
AFTERNOON AND TONIGHT. THE WINDS ARE EXPECTED TO SHIFT FROM THE
NORTHEAST TONIGHT...PROVIDING A MORE TYPICAL WEATHER PATTERN FOR
THIS TIME OF THE YEAR...WITH ISOLATED TO SCATTERED PASSING SHOWERS
DURING THE NIGHTS OVER NORTHERN AND EASTERN SECTIONS OF PUERTO RICO
AND LIMITED DAYTIME SHOWER ACTIVITY. SOME CHANGES WERE DONE TO THE
PREVIOUS FORECAST PACKAGE TO LOWER THE POPS IN SEVERAL
ZONES.

The San Salvador Volcano cam says it all about how good is the weather over there.

[msbee]

[Macrocane]

Yes, it's sunny with a nice breeze, a very great day. It's interesting to see how the US East coast has a snowy christmas, in centralamerica we have a sunny day and some of the Caribbean islands are having a rainy day. That's why I like this forum, because we can learn about the weather and experiencies in other places.

Exactly,that is the main purpose for me to create this kind of thread where all who live in the region can tell us how is the weather in their places.As you said not always is the same in all the islands or countries.And to make it more atractive,the radars and web cams that are in the first post of the thread will be of great importance when a threat from a tropical system or other big weather events occur,the members can go there and see what is going on.
