Caribbean - Central America Weather

[cycloneye]

Hi, El Salvador is under tsunami warning and the sea level may experience a change at 4:00 pm today, that's in about 11 hours, I will keep you updated hopefully nothing major will happen as it was the case with Chile earthquake last year, but let's be prepared.

Hopefully,nothing bad occurs over there nor anywhere in the Centralamerican coast,Mexico and South America. Keep us informed.

[Macrocane]

This is a weather and seismic update:
-The anticipated northerly winds arrived after midnight and cooler minimum temps have been registered in some of the countries and strong wind gusts have been experienced as well. I will post observations this evening as usual
-An 4.8 earthquake was felt in Nicaragua and the eastern part of El Salvador, no damages have been reported. Here's more info about that quake: http://www.storm2k.org/phpbb2/viewtopic.php?f=67&t=107415&p=2119979#p2119979

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
401 PM AST FRI MAR 11 2011

.SYNOPSIS...A MID TO UPPER LEVEL RIDGE ACROSS THE WESTERN ATLANTIC
AND NORTHERN CARIBBEAN ISLANDS WILL RESULT IN A GENERALLY FAIR AND
MAINLY DRY WEATHER PATTERN ACROSS PUERTO RICO AND THE USVI TONIGHT
THROUGH AT LEAST EARLY NEXT WEEK.

A MUCH DRIER AIR MASS IS FORECAST TO MOVE OVER THE LOCAL REGION
GENERATING FAIR AND MAINLY DRY WEATHER CONDITIONS THROUGH AT LEAST
THE INCOMING WEEK AS THE AFOREMENTIONED MID TO UPPER LEVEL RIDGE AND
AN OVERALL DRY AND STABLE AIR MASS DOMINATES THE LOCAL AREA.

TONIGHT THROUGH AT LEAST SUNDAY EXPECT A FEW EARLY MORNING LIGHT
SHOWERS ACROSS THE NORTHERN COAST OF PUERTO RICO AND THE USVI FROM
TIME TO TIME...WITH CHANCE OF AN ISOLATED AFTERNOON SHOWER OR TWO
ACROSS THE CORDILLERA CENTRAL. AFTERNOON CONVECTION...IF
ANY...SHOULD DISSIPATE BEFORE SUNSET LEAVING PARTLY CLOUDY SKIES.

&&

.DISCUSSION...ISOLATED TO SCATTERED SHOWERS CONTINUE TO AFFECT THE
NORTHERN PORTIONS OF PUERTO RICO THROUGH MIDDAY. THESE SHOWERS DID
NOT GENERATE ANY SIGNIFICANT RAINFALL ACCUMULATIONS. AT THIS
MOMENT SHOWERS STARTED TO AFFECT THE SOUTHWEST PORTIONS OF PUERTO
RICO...THESE SHOWERS ARE EXPECTED TO DISSIPATE BEFORE SUNSET.

&&

.AVIATION...PREVAILING VFR CONDITIONS WILL CONTINUE ACROSS THE LOCAL
ISLANDS AND AT ALL TAF SITES THROUGH AT LEAST THE NEXT 24 HOURS.
HOWEVER...VERY BRIEF MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURATIONS
ARE POSSIBLE IN ISOLATED AREAS. LIGHT PASSING SHOWERS ARE POSSIBLE
THIS EVENING...AND LATE NIGHT/EARLY MORNING PATCHY FOG OVER THE
INTERIOR SECTIONS OF PUERTO RICO.

&&

.MARINE...A PULSE OF SWELL WILL ARRIVE LATE TONIGHT AND SATURDAY...
RESULTING IN ROUGH AND HAZARDOUS MARINE CONDITIONS ACROSS THE OFF
SHORE ATLANTIC WATERS.

Good evening. At this time 3 tsunami waves were registered in El Salvador but they were not very high and no damages have been reported, according to the SNET the increase in the normal level was only 0.3 m or 1 ft, the normal wave height is 1.7 m so the waves were of 2 meters more or less. In Guatemela the increase was only 0.1 meters and no damages are reported either. I've not found more info about the height of the waves in other countries but there are no reports of damages thankfully.

In the case of Guatemala, El Salvador, Honduras and Costa Rica March has been cooler than normal so far, in fact March has been similar or even cooler than February in these countries, it will be intresting to see if the second half of March stays the same or has warmer temps.

Flood Safety Awareness Week in Puerto Rico

Is very important to have this event because of the many flood events that occur annually here,to have the public interested in this.

http://www.srh.noaa.gov/sju/?n=2011_floodawarenesssju

[Macrocane]

Interesting cycloneye, and many of those advices are helpful not only in Puerto Rico and US but in every part of the world that may be affected by floods.

Here's the rainfall that has fallen in different El Salvador stations on the first twon months of 2011, in half of the stations the rainfall has been above normal and in the other half it has been near or below normal. The graphic shows the long term average in red and the 2011 rainfall in blue. As you can see the long term average of rainfall for Jan-Feb is very low and no station has an average above 20 mm (0.8 inches) but this year some of the stations have seen well above average rainfall with the most extreme case being La Palma that has experienced 150 mm (5.9 inches) when its average is 10 mm (0.39 inches). This graphic doesn't show the rains registered this month that have been heavy in some of the stations.
