UPDATE...A VERY WELL DEVELOPED TROPICAL WAVE EAST OF CORPUS
CHRISTI AND SOUTH OF SABINE PASS HAS CONVECTION WRAPPED AROUND
THREE QUARTERS OF THE DISTURBANCE. MINOR COASTAL FLOODING IS
ONGOING AT COASTAL LOCATIONS SUCH AS CAMERON AROUND HIGH TIDE.
SINCE TIDES ARE GOING OUT...CANCELLED THE COASTAL FLOOD WATCH FOR

PROBABLY BE REISSUING THE COASTAL FLOOD WATCH FOR TONIGHT AS THE
TROPICAL WAVE CONTINUES TO SHOW SIGNS OF DEVELOPMENT.

NO OTHER CHANGES NEEDED TO THE ZONES. WILL REISSUE THE ZONES ONLY
FOR UPDATED COASTAL PRODUCTS AND REFRESHING THE WINDS.

UPDATE...DEEP TROPICAL MOISTURE WILL CONTINUE TO FLOW INTO THE
REGION BETWEEN HIGH PRESSURE OVER THE EASTERN CONUS AND AN
EASTERLY WAVE OVER THE WESTERN GULF. THIS WILL SET THE STAGE FOR
CONSIDERABLE SHOWER AND THUNDERSTORM ACTIVITY...OCCASIONAL MVFR
CEILINGS AND REDUCED VISIBILITY IN RAINS.

PREV DISCUSSION... /ISSUED 348 AM CDT WED JUL 7 2010/

SYNOPSIS...
A BROAD TROPICAL WAVE EXTENDING FROM THE SOUTHERN LOUISIANA COAST
TO THE WESTERN YUCATAN WILL MOVE TO THE WEST-NORTHWEST TODAY
THROUGH THURSDAY...WITH WAVE AXIS MOVING ALONG THE TEXAS AND
NORTHERN MEXICAN COAST THURSDAY AFTERNOON. GUIDANCE DOES SHOW SOME
POTENTIAL FOR A SURFACE LOW TO DEVELOP ALONG THE WAVE AXIS IN THE
SOUTHERN GULF...WITH GUIDANCE CLUSTERING ANY LOW MOVING ONSHORE
THE DEEP SOUTH TEXAS OR NORTHEAST OLD MEXICO COAST.

IMPACTS FOR THE FORECAST AREA WILL BE A CHANCE FOR SOME HEAVY
RAINFALL...SMALL CRAFT ADVISORY WINDS OVER THE COASTAL
WATERS...AND TIDES RUNNING ABOUT 1.5 TO 2 FEET ABOVE PREDICTED
LEVELS ALONG THE COAST WHICH MAY PRODUCE SOME MINOR COASTAL
FLOODING. VARIOUS HAZARDS HAVE ALREADY BEEN ISSUED BY PREVIOUS
SHIFTS AND SEE NO REASON TO CHANGE THESE AT THIS TIME. THESE
HAZARDOUS ARE AS FOLLOWS:

FLOOD WATCH TODAY FOR SOUTH CENTRAL AND EAST CENTRAL LOUISIANA...
A DECENT SWATCH OF HEAVY RAINFALL OCCURRED ON TUESDAY WITH AROUND
3 TO 7 INCHES FROM UPPER SAINT MARTIN PARISH THROUGH IBERIA PARISH
INTO NORTHERN SAINT MARY PARISH. WITH THE POTENTIAL FOR ADDITIONAL
1 TO 2 INCHES OF RAINFALL TODAY...WITH ISOLATED HIGHER
AMOUNTS...AND POOR DRAINAGE AS TIDES ALONG THE COAST REMAIN
HIGH...THESE AREAS WILL HAVE A CHANCE OF SEEING SOME FLOODING.
EVEN THOUGH HEAVY RAINFALL POTENTIAL EXISTS ACROSS THE REMAINDER OF
THE AREA...FLASH FLOOD GUIDANCE IS ON THE HIGH SIDE AS SIGNIFICANT
RAINFALL DID NOT OCCUR IN THESE AREAS OVER THE PAST COUPLE OF DAYS.

COASTAL FLOOD WATCH THROUGH THURSDAY EVENING ALONG THE ENTIRE COAST...
TIDES THIS MORNING ALONG THE LOUISIANA COAST ARE RUNNING BETWEEN
1.5 AND 2 FEET ABOVE PREDICTED LEVELS. THIS CREATING ACTUAL TIDE
LEVELS AROUND 3.5 FT MLLW. CAMERON SHERIFF REPORTED A LITTLE WATER
ON THE ROAD NEAR THE COURTHOUSE THIS MORNING DURING HIGH TIDE.
WITH THE EAST-SOUTHEAST WIND EXPECTED TO INCREASE TODAY AND LOWER
PRESSURE OVER THE GULF...TIDE LEVELS SHOULD REMAIN ELEVATED AS
TIDAL WATER PILING ALONG THE COAST CONTINUES. TIDE GUIDANCE SHOWS
ACTUAL TIDE LEVELS HIGHER ON WEDNESDAY NIGHT/EARLY THURSDAY
MORNING BETWEEN 3.5 AND 4.0 FT MLLW. THEREFORE...THERE WILL BE THE
POTENTIAL FOR SOME MINOR COASTAL FLOODING IN THE USUAL LOW SPOTS.

SMALL CRAFT ADVISORY ENTIRE COASTAL WATERS THROUGH THURSDAY...
PRETTY TIGHT PRESSURE GRADIENT ALONG THE WAVE HELPING TO CURRENTLY
PRODUCE SMALL CRAFT ADVISORY WINDS OVER THE EASTERN PORTIONS OF
THE COASTAL WATERS. THESE SCA WINDS WILL CONTINUE TO PROGRESS
EASTWARD TODAY WITH THE WAVE...WHICH WILL ALSO ALLOW SEAS TO BUILD TO
7 TO 9 FEET OFFSHORE. WINDS AND SEAS WILL GRADUALLY DECREASE LATE
THURSDAY INTO THURSDAY NIGHT AS THE WAVE MOVES ONSHORE AND AWAY
FROM THE COASTAL WATERS.

RUA

DISCUSSION...
LARGE TROPICAL CONNECTION EXTENDING FROM YUCATAN WILL CONTINUE TO
INCREASE TODAY AS A TROPICAL WAVE MOVES WEST-NORTHWEST ACROSS THE
GULF OF MEXICO. PRECIPITABLE WATER VALUES ARE EXPECTED TO INCREASE
TO BETWEEN 2.25 TO 2.5 INCHES TODAY WITH MEAN RH VALUES OVER 80
PERCENT. WITH THIS TROPICAL AIRMASS IN PLACE...CONVECTIVE
TEMPERATURES WILL BE ON THE LOW SIDE AND WILL NOT TAKE MUCH TO GET
SHOWERS AND THUNDERSTORMS GOING. RADAR ALREADY SHOWING A DECENT
COVERAGE OF NOCTURNAL SHOWERS OVER THE GULF. THEREFORE...NUMEROUS
SHOWERS AND THUNDERSTORMS SHOULD BE OCCURRING OFF AND ON TODAY.
THE MAIN CONCERN WITH THE ACTIVITY WILL BE THE POSSIBILITY OF
LOCALLY HEAVY RAINFALL. ACTIVITY SHOULD CONTINUE INTO THE EARLY
EVENING HOURS...WITH SOMEWHAT OF BREAK DURING THE LATE EVENING
BEFORE ACTIVITY...AS WITH A TROPICAL AIRMASS...REDEVELOPS DURING
THE LATE OVERNIGHT.

ON THURSDAY...THE WAVE AXIS...AND BEST TROPICAL MOISTURE WILL
SHIFT TO THE WEST...WITH SOUTHEAST TEXAS HAVING THE BEST CHANCE
FOR SHOWERS AND THUNDERSTORMS.

ON FRIDAY...THE TROPICAL WAVE WILL MOVE FURTHER INTO TEXAS AND
NORTHERN OLD MEXICO...WITH MID/UPPER LEVEL RIDGE BUILDING INTO THE
FORECAST AREA FROM THE NORTHEAST...AND THIS WILL HELP REDUCE THE
CHANCE FOR RAIN.

RAIN CHANCES LOOK TO BE IN THE SLIGHT CHANCE RANGE AT BEST OVER
THE WEEKEND AS MID/UPPER LEVEL RIDGE MOVES OVER THE FORECAST AREA.
THIS SHOULD ALSO HELP KEEP A FRONT FROM THE NORTHWEST FROM MAKING
IT INTO THE FORECAST AREA.

RUA

MARINE...
LATEST MSAS ANALYSIS AND MARINE OBSERVATIONS SHOW SMALL CRAFT
ADVISORY WINDS FROM SOUTH OF MARSH ISLAND AND POINTS TO THE EAST.
AS THE TROPICAL WAVE MOVES ACROSS THE GULF OF MEXICO...SMALL CRAFT
ADVISORY WINDS OF 20 TO 25 KNOTS SHOULD ALSO MOVE ACROSS THE
FORECAST AREA...WITH SEAS NEAR SHORE 3 TO 5 FEET AND OFFSHORE FROM
7 TO 9 FEET. THE EAST-SOUTHEAST WIND DIRECTION SHOULD PROVIDE THE
POTENTIAL FOR WATER PILING ALONG THE COAST WITH TIDES RUNNING 1.5
TO 2 FEET ABOVE ASTRONOMICAL PREDICTED LEVELS. THE GRADIENT
ASSOCIATED WITH THE WAVE SHOULD CONTINUE TONIGHT INTO
THURSDAY...THEN DIMINISH ON THURSDAY NIGHT AS THE WAVE MOVES
INLAND THE TEXAS AND NORTHERN OLD MEXICO COAST.

WEAK HIGH PRESSURE WILL THEN BUILD ACROSS THE NORTHERN GULF OF
MEXICO...WITH MAINLY LIGHT ONSHORE FLOW OVER THE WEEKEND.
