.SYNOPSIS...TUTT LOW OVER PUERTO RICO AND THE VIRGIN ISLANDS. A
MID LEVEL SHORT WAVE TROUGH EXTENDING ACROSS THE REGION AND WILL
SHIFT SLOWLY WESTWARD THROUGH SATURDAY...AS HIGH PRESSURE RIDGE
BUILDS OVER THE TROPICAL ATLANTIC. AN AMPLIFYING POLAR TROUGH
WILL EXIT THE EASTERN SEABOARD OF THE UNITED STATES AND SPREAD
EASTWARD OVER THE WESTERN ATLANTIC. THIS IN TURN WILL ERODE THE
UPPER RIDGE OVER THE WEST AND CENTRAL ATLANTIC NORTH OF THE REGION.
WEAK SURFACE HIGH PRESSURE RIDGE NORTH OF THE AREA WILL CONTINUE
TO LIFT NORTH AND EAST OF THE AREA TO MAINTAIN A LIGHT EASTERLY
TRADE WINDS TODAY AND INTO THE WEEKEND.

&&

.DISCUSSION...MID TO UPPER LEVEL TUTT LOW AND ASSOCIATED TROUGH
WILL CONTINUE TO WEAKEN THE CAP INVERSION. THIS WILL ALLOW FOR
BETTER LOW LEVEL INSTABILITY AND MIXING AS WELL AS BETTER SEA
BREEZE CONVERGENCE TODAY AND SATURDAY. AVAILABLE MOISTURE ACROSS
THE REGION...ALONG WITH LOCAL AND DIURNAL EFFECTS WILL AID IN
AFTERNOON CONVECTIVE DEVELOPMENT MAINLY ACROSS PARTS OF PUERTO
RICO. SOME ENHANCED CONVECTION WILL AGAIN REMAIN POSSIBLE TODAY
MAINLY OVER THE PORTIONS OF WESTERN PUERTO RICO. HOWEVER...THE
AFTERNOON CONVECTION IS NOT EXPECTED TO BE AS INTENSE AS THE
PREVIOUS DAY...AS THE MID LEVEL SHORT WAVE TROUGH AND ASSOCIATED
VORTICITY MAXIMA IS EXPECTED TO SHIFT FARTHER WEST ACROSS THE MONA
PASSAGES BY MID DAY TODAY.

THE TUTT WILL CONTINUE TO SHIFT FARTHER WEST OF THE ISLANDS WHILE
WEAKENING OVER THE NEXT FEW DAYS. AS THIS FEATURE WEAKENS...MID TO
UPPER LEVEL RIDGE WILL THEN SLOWLY BUILD ACROSS THE FORECAST AREA...
AND HOLD THROUGH AT LEAST THE MIDDLE OF NEXT WEEK. A WEAK TROPICAL
WAVE IS STILL FORECAST TO MOVE ACROSS THE REGION LATE SUNDAY OR MONDAY...
BUT NO SIGNIFICANT MOISTURE ADVECTION OR UPPER LEVEL SUPPORT IS SUGGESTED
AT THIS TIME. DURING THE LATTER PART OF THE FORECAST PERIOD ANOTHER
ACTIVE TROPICAL WAVE IS FORECAST TO APPROACH THE REGION. THIS FEATURE
HOWEVER IS STILL SOME WAYS OUT...SO WILL HAVE TO MONITOR AND SEE HOLD
IT UNFOLDS AND THE MODEL GUIDANCE ADJUSTS WITH TIME.

.SYNOPSIS...
AN UPPER LEVEL TROUGH WILL LINGER OVER THE AREA DURING THE
WEEKEND. IT IS EXPECTED TO WEAKEN AS IT MOVES WESTWARD OVER THE
WESTERN CARIBBEAN. A MID LEVEL RIDGE IS EXPECTED TO BUILD OVER THE
REGION...AS IT MOVES FROM THE CENTRAL ATLANTIC INTO EASTERN
CARIBBEAN DURING THE UPCOMING DAYS. A WEAK TROPICAL WAVE IS
EXPECTED TO REACH THE LOCAL AREA BY LATE TONIGHT INTO EARLY
SATURDAY MORNING. ANOTHER TROPICAL WAVE IS EXPECTED TO REACH THE
ISLANDS SUNDAY INTO MONDAY.

&&

.DISCUSSION...
MOSTLY SUNNY SKIES PREVAILED ACROSS THE LOCAL AREA DURING THE
MORNING HOURS. CLOUDINESS AND SHOWERS INCREASED OVER THE LOCAL
AREA DURING THE AFTERNOON HOURS. SHOWER ACTIVITY DEVELOPED OVER ST
CROIX AND ST JOHN AROUND NOON HOURS. ALSO...AFTERNOON SHOWERS
DEVELOPED OVER CAROLINA...CANOVANAS...COAMO...VILLALBA...OROCOVIS
AND TRUJILLO ALTO BY EARLY AFTERNOON. THE AFTERNOON CONVECTION
MOVED OVER THE INTERIOR AND WESTERN SECTIONS OF PUERTO RICO BY
EARLY AFTERNOON HOURS. ENHANCE CONVECTION REMAINS POSSIBLE DUE TO
THE PROXIMITY OF AN UPPER LEVEL TROUGH...THE AVAILABLE MOISTURE
AND LOCAL EFFECTS. SHOWER AND THUNDERSTORM ACTIVITY WILL CONTINUE
AT LEAST UNTIL EVENING HOURS.

TRANQUIL WEATHER CONDITIONS PRECEDING A WEAK TROPICAL WAVE WHICH
IS EXPECTED TO REACH THE LOCAL AREA BY LATE TONIGHT INTO EARLY
SATURDAY MORNING. THE TROPICAL WAVE AND THE UPPER LEVEL TROUGH
WILL ENHANCE THE INSTABILITY AND THE POTENTIAL FOR SHOWERS AND
THUNDERSTORMS MAINLY OVER THE SOUTH AND EASTERN SECTIONS OF PUERTO
RICO AND THE US VIRGIN ISLANDS.

ANOTHER TROPICAL WAVE IS EXPECTED TO REACH THE LOCAL AREA BY
SUNDAY INTO MONDAY...TO INCREASE THE POTENTIAL FOR SHOWERS AND
THUNDERSTORMS.

.SYNOPSIS...MID TO UPPER LEVEL RIDGE WILL CONTINUE TO SHIFT WESTWARD
FROM ACROSS THE TROPICAL ATLANTIC AND DISPLACE THE TUTT WHICH WILL
MOVE FARTHER WEST OF THE REGION. ASSOCIATED TUTT LOW WILL CONTINUE
TO LIFT WEST NORTHWEST WHILE WEAKENING. A TUTT INDUCED LOW LEVEL
TROUGH WITH AXIS NOW CROSSING THE EASTERN CARIBBEAN WILL CONTINUE
WESTWARD ACROSS THE FORECAST AREA DURING THE REST OF THE DAY. NO
SIGNIFICANT AMOUNTS OF MOISTURE WAS NOTED ACCOMPANYING THIS FEATURE.
HOWEVER...SATELLITE IMAGERY AND DOPPLER WEATHER RADAR BOTH SUGGEST
SHALLOW MOISTURE AND CONVECTION MOVING ACROSS THE REGIONAL WATERS
AND BRUSHING PART OF THE COASTAL AREAS THIS MORNING.

ANOTHER TROPICAL WAVE WITH AXIS NEAR 57 WEST...WILL ENTER AND
MOVE ACROSS THE EASTERN CARIBBEAN LATER TONIGHT THROUGH SUNDAY.
FRAGMENTS OF MOISTURE JUST AHEAD OF AND TRAILING THE WAVE WILL
MOVE WESTWARD ACROSS THE REGIONAL WATERS LATER TONIGHT THROUGH
SUNDAY. AT THIS TIME...NO SIGNIFICANT DEEP MOISTURE ADVECTION IS
ANTICIPATED WITH THIS WAVE.

&&

.DISCUSSION...FAIRLY LIGHT EASTERLY TRADES ARE TO PERSIST DURING
THE NEXT FEW DAYS...AS WEAK SURFACE HIGH PRESSURE RIDGE WILL LINGER
NORTH OF THE REGION. THIS IS TO SUPPORT A LOOSE LOCAL PRESSURE GRADIENT
RESULTING IN INCREASING LAND AND SEA BREEZE CONVERGENCE. THE APPROACHING
WAVE ALONG WITH MOISTURE CONVERGENCE AND DIURNAL EFFECTS WILL GIVE WAY
TO AFTERNOON CONVECTION ACROSS PARTS OF THE CENTRAL AND WEST SECTIONS
OF PUERTO RICO DURING THE AFTERNOON HOURS. PASSING SHOWERS WILL CONTINUE
TO AFFECTS PARTS OF EASTERN PUERTO RICO AS WELL AS PORTIONS OF THE VIRGIN
ISLANDS DURING THE REST OF THE MORNING HOURS.

BY SUNDAY...AS THE TROPICAL WAVE MOVES ACROSS THE REGION EXPECT
ANOTHER QUICK SURGE OF MOISTURE TO AFFECT THE AREA. THIS WILL
AGAIN SUPPORT MOISTURE CONVERGENCE AND LOCALLY AND DIURNALLY
INDUCED EARLY MORNING AND AFTERNOON CONVECTION ACROSS PORTIONS OF
THE ISLANDS. SOME OF THE AFTERNOON CONVECTION OVER PUERTO RICO
MAY BE ENHANCED DURING THE TIME OF MAX HEATING PARTICULARLY IN
THE WEST AND NORTHWEST INTERIOR OF PUERTO RICO.

IMPROVING WEATHER CONDITIONS EXPECTED DURING THE EARLY AT OF NEXT WITH
AS HIGH PRESSURE BUILDS ALOFT AND THE CAP INVERSION STRENGTHENS ONCE
AGAIN OVER THE AREA....LIMITING CONVECTIVE DEVELOPMENT.

SHRA EXPECTED UNTIL 05/14Z ACROSS TNCM...TKPK AND ACROSS THE EASTERN
TAF SITES OF PUERTO RICO AND USVI...TIST...TISX AND TJSJ AS A WEAK
EASTERLY WAVE WILL MOVE ACROSS THE FLYING AREA. PERIODS OF SHRA/TSRA
EXPECTED AFTER 05/16Z ACROSS SEVERAL SECTORS IN PR WHICH WILL LIKELY
CAUSE VCTS FOR TJBQ/TJMZ/TJSJ/TJPS...AS WELL AS POSSIBLY AFFECT THE
ACTUAL STATION...CAUSING MVFR COND UNTIL 05/23Z. WINDS WILL BE MAINLY
LGT AND VRB THIS MORNING...BECOMING E-SE AT AROUND 10KT WITH SEA BREEZE
VARIATIONS AFTER 05/14Z.

Invest 91-L: Tropical Wave Should Become the Next Atlantic Named Storm

By Quincy Vagell

Published Sep 5 2015 05:32 AM EDT

weather.com

http://www.weather.com/storms/hurricane ... 5-atlantic

•A tropical wave, designated Invest 91-L, is being monitored in the far eastern Atlantic for possible development into a tropical depression or storm.
•This could occur anytime over the next five days.
•This disturbance is moving west at 15-20 mph and, unlike Fred, is remaining south of the Republic of Cabo Verde.
•It remains far too soon to determine if this system will survive the long journey to the Lesser Antilles, or succumb to dry air and/or wind shear lying ahead.
•The next named storm in the Atlantic basin is "Grace". In an average year, the seventh Atlantic named storm forms by September 16.

[cycloneye]

8 AM TWO:

Up to 80%-90

Satellite images and ship observations this morning indicate that a
tropical depression could be forming about 200 miles south of the
Cape Verde Islands. If this trend continues, advisories would be
initiated later today. Environmental conditions appear to be
favorable for additional development, at least for the next two or
three days, while the system moves westward at 15 to 20 mph across
the tropical Atlantic.
* Formation chance through 48 hours...high...80 percent
* Formation chance through 5 days...high...90 percent
