The radar

The San Juan radar (TJUA), 14 km from the middle of the area, began a volume at 20:11 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The text

As transmitted, in the capitals the NWS used until 2016.

Area forecast discussion, May 8, 9:47 AM CDT, 5 hours 24 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1047 AM AST FRI MAY 8 2009

.UPDATE...MOSTLY SUNNY SKIES PREVAILED ACROSS THE LOCAL AREA THIS
MORNING. FOR THE REST OF THE DAY...AND THE AFTERNOON
HOURS...AVAILABLE MOISTURE WILL COMBINE WITH LOCAL EFFECTS...TO
PRODUCE SCATTERED TO NUMEROUS SHOWERS WITH ISOLATED THUNDERSTORMS
MAINLY ACROSS THE CORDILLERA CENTRAL THIS AFTERNOON. LATEST 12Z
TJSJ SOUNDING INDICATED PW VALUES OF 2.01 INCHES...WHICH INDICATED
A MOIST ATMOSPHERE MAINLY AT THE SURFACE...WHICH WILL HELP IN THE
DEVELOPMENT OF SHOWERS THIS AFTERNOON. A LITTLE ADJUSTMENT WAS
MADE TO MAX TEMP FOR THIS AFTERNOON ACROSS THE SAN JUAN METRO
AREA...INCREASING A COUPLE OF DEGREES...DUE TO MORE SUNSHINE..AND
LESS CLOUD COVER THIS MORNING...WHICH WILL ALLOW FOR BETTER DAYTIME
HEATING THIS AFTERNOON. NO OTHER CHANGES WERE MADE TO FORECAST
REASONING.

&&

.AVIATION...EXPECT SURFACE WINDS GENERALLY FROM THE EAST AT 10-20KTS AT
ALL TAF SITES...EXCEPT ACROSS TJMZ...WHERE VARIABLE WINDS ARE
EXPECTED THIS AFTERNOON. EXPECT SHRA DEVELOPMENT POSSIBLE ACROSS
EASTERN PR AND THE VI 17-22Z. IN ADDITION...ISOLATED TSRA WILL BE
POSSIBLE OVER THE NORTH CENTRAL AND WEST INTERIOR SECTIONS OF PR
AS WELL AS IN THE VICINITY OF TJMZ...TJBQ...AND TJPS AFTER 18Z.

&&

.PREV DISCUSSION... /ISSUED 549 AM AST FRI MAY 8 2009/

SYNOPSIS...UPPER LEVEL TROUGHFINESS EXPECTED TO DOMINATE THE
LOCAL AREA THROUGH EARLY SATURDAY...THEN A MORE ZONAL FLOW
EXPECTED TO TAKE OVER THE CARIBBEAN FOR THE REST OF THE UPCOMING
WEEKEND. AFTERWARD...A RIDGING NORTHWEST FLOW WILL BE WITH US FOR
MUCH OF THE APPROACHING WEEK.

AT MID LEVELS...A WEAK SOUTHERLY FLOW PROJECTED TO PREVAIL ACROSS
THE LOCAL AREA FOR THE NEXT FEW DAYS AS HIGH PRESSURE RIDGE
WEAKENS NORTHEAST OF THE FORECAST AREA...AND AN AREA OF HIGH
PRESSURE BUILDS NORTH OF BAHAMAS.

AT LOW LEVELS...HIGH PRESSURE SYSTEM IS CONTROLLING THE ATLANTIC
BASIN...CREATING A MODERATE TO FRESH EASTERLY WIND FLOW ACROSS THE CWA.
THIS HIGH WILL REMAIN IN PLACE FOR THE NEXT FOUR TO FIVE DAYS AT
LEAST. THEREFORE...WE WILL CONTINUE UNDER THE SAME TRADE WIND FLOW
REGIME.

ON THE OTHER HAND...THIS FLOW WILL CONTINUE TO BRING PATCHY CLOUDS
AND SHOWERS ACROSS THE LOCAL ISLANDS FOR DAYS AND DAYS TO COME.

DISCUSSION...LATEST WATER VAPOR IMAGERY SHOWING SOUTHWEST FLOW
ALOFT ACROSS THE FORECAST AREA. THIS FLOW IS STREAMING MID TO
UPPER LEVEL CLOUDS ACROSS THE AREA DISCUSSION FROM CENTRAL AMERICA AND
THE NORTHERN PART OF SOUTH AMERICA. AS APPEARS ON
SATELLITE...THESE CLOUDS LOOK LIKE THEY WILL BE LINGERING AROUND
FOR ONE OR TWO DAYS. THEREFORE...VARIABLY TO MOSTLY CLOUDY SKIES TO
GOVERN THE LOCAL AREA FOR THIS PERIOD.

AT LOW LEVELS...A MOIST TROPICAL AIR MASS WILL CONTINUE TO PUSH
GROUP OF CLOUDS AND SHOWERS FROM THE NORTHEASTERN CARIBBEAN
TOWARDS THE FORECAST AREA. THIS WET WEATHER PATTERN IS ANTICIPATED
TO PERSIST THROUGH THE WEEKEND WITH A SMALL BREAK PROJECTED FOR
LATE SUNDAY INTO MONDAY. AFTERWARD...A WET PATTERN RETURNS FOR
MUCH OF THE UPCOMING WEEK.

EXPECT MODERATE TO HEAVY INTENSITY SHOWERS AND EVEN A FEW
THUNDERSTORMS TO POP ACROSS THE AREA WATERS AND OVER THE CENTRAL
INTERIOR...PARTS OF THE NORTHERN COASTS AND NORTHWEST PUERTO RICO
THIS AFTERNOON. ONCE THE EVENING...ARRIVE...MOST OF THIS ACTIVITY
SHOULD BE CALMING DOWN. HOWEVER...WITH THIS AFTERNOON SHOWER
ACTIVITY...SOME MINOR FLOODING ARE EXPECTED TO OCCUR OVER SOME
AREAS. ALSO...THE RISK OF MUDSLIDES STILL EXIST MAINLY ACROSS THOSE
AREAS AFFECTED EARLY IN THE WEEK AS SOILS ARE NEAR SATURATION STAGE.

AVIATION...PERIODS OF IFR/MVFR CONDITIONS EXPECTED ACROSS TNCM AND
TKPK AT LEAST THROUGH 10Z DUE TO PASSING SHOWERS. PREVAILING VFR
CONDITIONS EXPECTED ACROSS ALL OTHER THE LOCAL TAF SITES DURING THE
EARLY MORNING HOURS WITH CIGS BETWEEN 4-10 KFT...AND WINDS GENERALLY
FROM THE EAST SOUTHEAST 5 TO 15 KNOTS. HOWEVER...EXPECT INTERMITTENT
MVFR IN PASSING SHRA AT LEAST THROUGH 12Z ENROUTE BTWN EASTERN
PUERTO RICO AND THE VIRGIN ISLANDS. THEREAFTER...EXPECT SFC WNDS
GENERALLY FROM THE EAST AT 10-20KTS AT ALL TAF SITES...WITH MORE
SHRA DEVELOPMENT POSSIBLE ACROSS EASTERN PR AND THE VI 17-22Z. IN
ADDITION...ISOLATED TSRA WILL BE POSSIBLE OVER THE NORTH CENTRAL AND
WEST INTERIOR SECTIONS OF PR AS WELL AS IN THE VCNTY OF TJMZ AND TJPS
AFTER 18Z.

MARINE...WIND DRIVEN WAVES FROM THE NORTHEAST WILL BE DOMINATING
THE REGIONAL WATERS FOR THE NEXT SEVERAL DAYS. FOR THE OFF SHORE
ATLANTIC WATERS...SCA IS IN EFFECT THROUGH LATE TONIGHT. SMALL
CRAFT SHOULD EXERCISE CAUTION ELSEWHERE.
