Good morning to all. Another very warm day is on tap for today.


AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
508 AM AST WED APR 28 2010

.SYNOPSIS...AT UPPER LEVELS...HIGH PRESSURE STRETCHES ALONG THE NORTHEAST
COAST OF SOUTH AMERICA AND INTO THE SOUTHEAST CARIBBEAN AS A MID-
LATITUDE LOW MOVES INTO THE WESTERN ATLANTIC. A TROUGH WILL DIG
ACROSS HISPANIOLA ON SUNDAY AND FORM A WEAK CUT-OFF LOW JUST
SOUTHWEST OF PUERTO RICO THAT WILL DEFORM INTO A WEAK TROUGH FROM
PUERTO RICO TO THE YUCATAN PENINSULA ON WEDNESDAY NEXT WEEK.

AT MID LEVELS...A RIDGE OF HIGH PRESSURE EAST OF THE LEEWARD
ISLANDS WILL BUILD ACROSS THE GREATER ANTILLES TODAY THROUGH
SATURDAY. THEN HIGH PRESSURE WILL MOVE TO FLORIDA ON MONDAY BEFORE
ELONGATING OVER THE BAHAMAS NEXT WEEK.

AT LOWER LEVELS...HIGH PRESSURE OVER THE CENTRAL ATLANTIC EXTENDS
SOUTHWEST INTO THE NORTHEAST CARIBBEAN AND ACROSS HISPANIOLA. A
STRONG COLD FRONT MOVING ACROSS CUBA WILL MOVE TOWARD THE LOCAL
AREA OVER THE WEEKEND AND WILL LIE ACROSS THE LOCAL WATERS LATE
SUNDAY. ON MONDAY AND TUESDAY IT IS EXPECTED TO MOVE THROUGH
PUERTO RICO AND THE NORTHERN VIRGIN ISLANDS. DRYER AIR WILL POUR
IN BEHIND THE FRONT WEDNESDAY THROUGH SATURDAY OF NEXT WEEK.


&&

.DISCUSSION...HAVE DISCARDED THE NAM AND GFS SOLUTIONS IN FAVOR OF
THE ECMWF DUE TO UNUSUAL CHARACTERISTICS OF EACH. THE NAM CREATES
A STRONG LOW- LEVEL LOW NORTHEAST OF THE AREA WHICH BRINGS
NORTHEAST WINDS OVER THE AREA THURSDAY. THIS IS LIKELY PREMATURE.
THE GFS BUILDS A MUCH STRONGER CUT-OFF LOW DIRECTLY OVER PUERTO
RICO SUNDAY AND MONDAY...THOUGH IT SEEMS TO HAVE LITTLE EFFECT AT
THE SURFACE OR IN THE MOISTURE FIELDS. THE ECMWF...HOWEVER...
DEVELOPED A WEAKER LOW SOUTHWEST OF PUERTO RICO AND BROUGHT IN A
BAND OF MOISTURE ABOUT THE SAME TIME AS THE GFS AND THIS SEEM TO
BE THE BEST SOLUTION. THIS WILL BRING MOSTLY DRY WEATHER TO THE
LOCAL AREA TODAY WITH INCREASING SHOWER ACTIVITY IN THE WEST
THURSDAY THROUGH SATURDAY. ON SUNDAY THE ECMWF BRINGS A FRONT INTO
THE NORTHERN PART OF THE AREA AND THIS SHOULD BRING CLOUDS AND
SPAWN MORE SHOWERS OVERALL. THIS BOUNDARY PERSISTS THROUGH TUESDAY
SINKING SLOWLY SOUTH...AFTER WHICH WE SHOULD SEE SUBSTANTIAL
CLEARING AND LESS SHOWERS.

RETURNING TO TODAY...SOUTHERLY WINDS UP THROUGH AT LEAST 5
THOUSAND FEET BETWEEN 20 AND 30 KNOT...ACCORDING TO THE TERMINAL
DOPPLER WIND PROFILE THIS MORNING...ARE EXPECTED TO BOOST
TEMPERATURES TODAY ON THE NORTH COAST. SAN JUAN...WHICH TIED THE
RECORD AT 93 YESTERDAY...MAY APPROACH THE RECORD AGAIN FOR TODAY
AT 94 DEGREES...AS MOS WAS FORECASTING THE SAME MAXIMUM...92...FOR TODAY
AS IT DID FOR YESTERDAY. THIS MAY BE TOO LOW...ESPECIALLY SINCE THE
MINIMUM SO FAR FOR TODAY IS 80 DEGREES...A FULL 3 DEGREES WARMER
THAN YESTERDAY AT THIS TIME. MODELS TRY TO BRING SHOWERS IN OVER
THE NORTHWEST AT THE WESTERN END OF WHAT APPEARS TO BE A HEAT LOW
ALONG THE NEAR COASTAL WATERS NORTH OF PUERTO RICO IN THE NAM AND
WRF...THE HIGHER RESOLUTION MODELS...BUT MOISTURE IS AS LOW AS IT
HAS BEEN FOR AT LEAST THE LAST 5 DAYS AND THIS MAY BE
DIFFICULT...SO HAVE LOWERED THE POPS BY 10 PERCENT ACROSS THE
ENTIRE AREA. SHOWERS MAY FIND MORE FAVORABLE CONDITIONS TOMORROW
IN THE WEST AS WINDS BEGIN TO SHIFT TO A MORE EASTERLY DIRECTION.

&&

.AVIATION...
PREVAILING VFR CONDITIONS ARE EXPECTED ACROSS ALL LOCAL
TAF SITES TODAY. LATEST TJSJ SOUNDING 28/00Z AND ...THE
METEOROLOGICAL DATA COLLECTION AND REPORTING SYSTEM CALLED...MDCRS...
WIND PROFILE...INDICATED SOUTH SOUTHEAST LLVL WINDS BETWEEN 5 TO
20 KNOTS FROM SFC TO 5 KFT. IN GENERAL...NO SIGNIFICANT WEATHER
FLYING HAZARDS ARE EXPECTED ACROSS THE REGION DURING THE NEXT 24
HOURS.

&&

.MARINE...SEAS INCREASE AROUND THE END OF THE WEEK AS GRADIENTS
TIGHTEN BETWEEN THE HIGH MOVING EAST ACROSS THE WESTERN ATLANTIC
AND THE LOW PRESSURE OVER THE SOUTHERN CARIBBEAN. THEY REACH A
MAXIMUM BOTH IN THE ATLANTIC AND THE CARIBBEAN DURING THE FIRST
TWO OR THREE DAYS IN MAY. SMALL CRAFT CONDITIONS WILL BE MARGINAL
IF THEY ARE REACHED AT ALL. SMALL CRAFT SHOULD EXERCISE CAUTION
AROUND THE U.S. VIRGIN ISLANDS DUE TO FUNNELING OF SOUTHERLY WINDS
AROUND THE ISLANDS...OTHERWISE MOST AREAS WILL BE BELOW
PRECAUTIONARY LEVELS.

Macrocane,is rainning over there today as the web cam from San Salvador shows. Still keeping an eye on the waters south of Central America to see if something gets going in the next few days.

Note=You can see many web cams from different islands in the Caribbean and from Central America on the first post of thread. Web cams from Central America apart from the San Salvador one includes various cams at the Panama Canal from the dfifferent locks and other points of interest in the canal.

[Macrocane]

It has been very cloudy but we've only had some drizzle this morning and light rain last night. There are other places that experienced heavy rain last night especially in the eastern third of the country. The accumulated rain between 7:00 am yesterday and 7:00 am today in some stations:

Acajutla (west coast): 24 mm/0.94 inches
San Salvador: 1 mm/0.04 inches
San Miguel (in east part of the country): 10 mm/0.39 inches
La Union (Gulf of Fonseca): 47 mm/1.85 inches

Special Weather Statement about the very warm temperatures in Puerto Rico

Is already 91F as I type this.

SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE SAN JUAN PR
1104 AM AST WED APR 28 2010

THE NATIONAL WEATHER SERVICE IN SAN JUAN HAS ISSUED A SPECIAL WEATHER
STATEMENT EFFECTIVE UNTIL 445 PM AST WEDNESDAY FOR PEOPLE ALONG THE
NORTH...WEST AND SOUTH COASTS.

...HIGH HEAT INDICES EXPECTED THIS AFTERNOON...

HOT TEMPERATURES IN THE MID 90S IN COMBINATION WITH HIGH RELATIVE
HUMIDITY VALUES WILL RESULT IN HIGH HEAT INDICES OF AROUND 105
DEGREES. EXPOSURE TO FULL SUNSHINE CAN INCREASE HEAT INDEX VALUES BY
UP TO 15 DEGREES. IN ADDITION...PROLONGED EXPOSURE OR PHYSICAL
ACTIVITY CAN LEAD TO HEAT CRAMPS AND HEAT EXHAUSTION.

HERE ARE SOME SAFETY TIPS...

1) SLOW DOWN AND DRINK PLENTY OF WATER OR OTHER NON-ALCOHOLIC
FLUIDS.
2) SPEND MORE TIME IN AIR-CONDITIONED PLACES.
3) EAT FOOD WITH LOW AMOUNTS OF PROTEINS. FOODS THAT INCREASE
METABOLIC HEAT PRODUCTION LIKE PROTEINS INCREASE WATER LOSS
IN YOUR BODY.

From NHC EPAC discussion.

http://www.nhc.noaa.gov/text/refresh/MI ... 1529.shtml?

A COLD FRONT IS LOSING IDENTITY FROM 32N118W TO 24N140W. N TO NE
WINDS W OF THE FRONT ARE EXPECTED TO PERSIST ON THE EASTERN
PERIPHERY OF A STRONG 1030 MB HIGH CENTERED NEAR 33N147W. NW
SWELLS CONTINUE TO PROPAGATE SOUTHEASTWARD INTO THE AREA AND
MERGE WITH LONGER PERIOD CROSS EQUATORIAL SW SWELL IN THE DEEP
TROPICS. THE PRESSURE GRADIENT IS FORECAST TO INCREASE OVER THE
NE PORTION OF THE DISCUSSION AREA OFF THE COAST OF BAJA
CALIFORNIA BY THIS EVENING REMAINING STRONG UNTIL LATE FRIDAY
WITH NORTHERLY WINDS GRADUALLY INCREASING 20 TO 30 KT OVER MOST
OF THE AREA N OF 20N E OF 129W BY EARLY FRIDAY. SOUTHERLY
MONSOON WINDS WILL INCREASE TO 20 TO 25 KT OVER THE AREA S OF
06N E OF 90W THURSDAY AND CONTINUE THROUGH THE WEEKEND. GLOBAL
GFS MODEL GUIDANCE DEPICTS A DEVELOPING AREA OF LOW PRESSURE
SOUTH OF COSTA RICA THROUGH THE FORECAST PERIOD...WHILE MOST
OTHER MODELS...INCLUDING THE ECMWF AND UKMET DOWNPLAY
DEVELOPMENT CONSIDERABLY SW OF THE CENTRAL AMERICA COASTLINE.
DUE TO WEAK LOW-LEVEL TROUGHING...INSTABILITY...AND IMPLIED
ATMOSPHERIC LIFT...THE MOST LIKELY IMPACTS WILL BE CONTINUED
AREAS OF SCATTERED MODERATE CONVECTION AND ISOLATED STRONG
CONVECTION OVER THE SE PACIFIC AND CENTRAL AMERICA THROUGH EARLY
NEXT WEEK.

feeling hot hot hot is an euphemisma Cycloneye!!!

[cycloneye]

Gusty,you always bring very original graphics It really was very hot as in other parts of the island it was hotter than San Juan. I was drinking many bottles of water to fight the heat. When I say many bottles,more than 15.

[msbee]

I drank a lot of water today too. it is so hot here too.

and we have a lot of haze over us.
Do you known what that is from, Luis or Gusty?

[Gustywind]

:uarrow: Gusty,you always bring very original graphics It really was very hot as in other parts of the island it was hotter than San Juan. I was drinking many bottles of water to fight the heat. When I say many bottles,more than 15.

Thanks my friend, i appreciate this attention Luis . I try to be very original with my artist sensibility in spite of the events good or bad, that's my way to escape from our stressed life. Glad to see that many are like you are there to show me that . Waouw more than 15? that's very amazing!!!! Sure that you were like that Cycloneye:

Hope that some water will fall during the next couple of days, let's wait and see.

[cycloneye]

I drank a lot of water today too. it is so hot here too.

and we have a lot of haze over us.
Do you known what that is from, Luis or Gusty?

The haze is Saharan Dust from Africa.

[Macrocane]

Very strong convection has developed near the Gulf of Fonseca and is moving westwards, I guess that some heavy rains may be occuring in the east part of El Salvador, I will post the observations tomorrow. Strong convection is occuring in Honduras and Nicaragua too so if I find observations from other central american countries I will post them tomorrow.

Good morning to all. Maybe not as hot as it was yesterday but still another warm day ahead.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
516 AM AST THU APR 29 2010

.SYNOPSIS...AT UPPER LEVELS...HIGH PRESSURE DOMINATES THE
CARIBBEAN UNTIL SUNDAY WHEN A TROUGH DIGS FROM THE NORTHEAST
ACROSS THE LOCAL AREA AND FORMS A WEAK CUT-OFF LOW BETWEEN PUERTO
RICO AND HAITI. A SECOND CUT-OFF MAY FORM JUST EAST OF THE LEEWARD
ISLANDS MID WEEK NEXT WEEK.

AT MID LEVELS...A RIDGE OF HIGH PRESSURE WILL GIVE WAY TO A LOW
JUST NORTH OF PUERTO RICO ON SUNDAY. LOW PRESSURE WILL MOVE INTO
THE CENTRAL CARIBBEAN EARLY NEXT WEEK WHILE THE HIGH MOVES OVER
FLORIDA ON MONDAY AND THEN TO THE NORTHEAST OF THE LEEWARD ISLANDS
ON WEDNESDAY. HIGH PRESSURE THEN RETURNS TO THE LOCAL AREA.
MOISTURE MOVES OVER THE AREA SUNDAY NIGHT THROUGH MONDAY NIGHT AND
AGAIN ON THE FOLLOWING FRIDAY.

AT LOWER LEVELS...A WEAK FRONT WILL MOVE INTO THE AREA ON SUNDAY
AND LINGER NEAR OR OVER PUERTO RICO AND THE U.S. VIRGIN ISLANDS
MONDAY THROUGH WEDNESDAY. DRIER AIR WILL FOLLOW.

&&

.DISCUSSION...TEMPERATURES ARE SIMILAR TO YESTERDAY BUT RADAR VAD
PROFILE SHOWS THAT WINDS HAVE SHIFTED FROM SOUTH TO EASTERLY OR
ARE VERY LIGHT IN THE LOWER LEVELS. 850 MB LEVEL WINDS BACK TO
EASTERLY NO LATER THAN 30/00Z IN THE GFS AND THE ECMWF...AND ARE EASTERLY
BY 29/21Z IN THE NAM. MOS TEMPERATURES ARE ACTUALLY HIGHER TODAY
THAN YESTERDAY FOR SAN JUAN...BUT WITH THE WEAKNESS IN THE
SOUTHERN COMPONENT OF THE LOW LEVEL WINDS...SEA BREEZES MAY WIN
OUT BEFORE 93 DEGREES AT SAN JUAN...WHICH TIES THE RECORD FOR
TODAY...CAN BE REACHED. MOS WAS TOO COOL YESTERDAY AND THE DAY
BEFORE BUT DID NOT RAISE IT TODAY DUE TO WINDS AFOREMENTIONED.
SATELLITE IMAGERY SHOWS THAT THE DUST LAYER COVERS MUCH OF THE
TROPICAL ATLANTIC PAST EVEN HAITI...SO DO NOT EXPECT HAZY SKIES TO
ABATE. ADDED HAZE TO THE GRIDS THIS MORNING TO LAST ABOUT 48
HOURS. SHOWERS WERE FAR AND FEW BETWEEN WEDNESDAY AND WITH DRY MID
LEVELS...HAZY SKIES AND NEARLY STABLE CONDITIONS EXPECT ONLY A FEW
SHOWERS TODAY...WITH THOSE BEING MAINLY IN THE WEST THIS AFTERNOON.

THE CUT-OFF LOW THAT ALL THE MODELS BEGIN TO DEVELOP IN THE
UPPER ATMOSPHERE OVER PUERTO RICO CONTINUES ESPECIALLY STRONG IN
THE GFS SUNDAY AND MONDAY...BUT OVERALL WEATHER CAUSED BY THIS LOW IN
THE MODEL SOLUTIONS REMAINS MODEST AND HAVE LOWERED EXPECTATIONS
OF RAIN SOMEWHAT IN THE GRIDS SATURDAY THROUGH TUESDAY.
NEVERTHELESS THIS WEATHER PATTERN SHOULD GENERATE SOME SHOWER
ACTIVITY...ESPECIALLY IN THE WEST AND WINDWARD COASTS. SHOWERS
WILL BE HELPED BY VERY MODEST MID LEVEL MOISTURE MONDAY AND
TUESDAY...BUT SHOWERS SHOULD ABATE ON WEDNESDAY AND DRIER WEATHER
IS EXPECTED AFTERWARD.

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL ACROSS ALL TAF SITES. HAZY
CONDITIONS AND BRIEFLY REDUCED VISIBILITIES BETWEEN 6-8 MILES WILL
CONTINUE AT SOME OF THE LOCAL TAF SITES FOR THE NEXT 12 TO 18 HOURS.
SFC WINDS WILL BE MAINLY FROM THE EAST SOUTHEAST AROUND 10 MPH WITH
HIGHER GUSTS EXCEPT FOR SEA BREEZE VARIATIONS AT COASTAL LOCATIONS
THIS AFTERNOON.

&&

.MARINE...WINDS WILL INCREASE AS HIGH PRESSURE BUILDS JUST NORTH
OF THE LOCAL AREA. THIS WILL CAUSE SEAS TO INCREASE NOW THROUGH
MONDAY MAY 3.

[Macrocane]

It's a cool and cloudy morning in most of El Salvador, in San Salvador it rained for a couple of hours after midnight but at this hour we only have the completely cloudy skies and dense fog in the high and mountainous areas. Later today I will post the rainfall amounts in parts of El Salvador.
