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.

Area forecast discussion, Jul 10, 2:30 AM CDT, 4 hours 3 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JUAN PR 330 AM AST MON JUL 10 2006 .DISCUSSION... TROPICAL WAVE INTERACTION GENERATING QUITE A BIT OF ACTIVITY MOSTLY OVER WATER EAST AND NORTH OF PUERTO RICO. HOWEVER...THE VIRGIN ISLANDS AS WELL AS THE EASTERN HALF OF PUERTO RICO GETTING THEIR SHARE OF WEATHER. SHOWERS WILL REMAIN RATHER NUMEROUS TODAY ACROSS THE ENTIRE AREA AND THUNDERSTORMS DEFINITELY SCATTERED. PERIODS OF LOCALLY HEAVY BUT FAST MOVING SHOWERS WILL BE EXPECTED TO CONTINUE TODAY BUT SWITCHING TO THE WEST HALF OF THE ISLAND BY LATE MORNING AND EARLY AFTERNOON. URBAN FLOODING WOULD BE THE MOST OBVIOUS RISK TODAY WITH THE HEAVIER SHOWERS. EVEN THOUGH THE UPPER TROUGH IS FORECAST TO RETREAT NORTHWEST EFFECTS WILL STILL BE NOTICEABLE. DRIER WEATHER IN STORE FOR TONIGHT THROUGH WEDNESDAY MORNING. SHOWERS AND ISOLATED THUNDERSTORMS WILL STILL OCCUR BUT JUST WHAT IS CONSIDERED THE NORMAL CLIMATE ACTIVITY. STRONGER WAVE TO APPROACH ON WEDNESDAY AND POTENTIALLY BRING ACTIVE WEATHER FOR WEDNESDAY NIGHT INTO THURSDAY. MODIFIED FORECAST TO ACCOUNT FOR MORE WEATHER ON THURSDAY SINCE GUIDANCE SUGGESTS WAVE IS TO MOVE WEST NORTHWEST AND TO AFFECT THE LOCAL AREA. && .SYNOPSIS... AT THE LOW LEVELS WE HAVE THE TROPICAL WAVE WITH AXIS TRACKING ACROSS 66 WEST OR OVER PUERTO RICO EARLY THIS MORNING BASED ON 88D CELL MOTION. WAVE IS INTERACTING WITH UPPER LEVEL TROUGH ORIENTED FROM SOUTHEAST TO NORTHWEST ACROSS HISPANIOLA. UPPER TROUGH IS FORECAST TO DRIFT FURTHER NORTHWEST AND ALSO WEAKEN THROUGH THIS EVENING. TROPICAL WAVE WILL CONTINUE ITS WAY INTO HISPANIOLA WITH HIGH PRESSURE BUILDING AND PREVAILING THROUGH WEDNESDAY. NEXT TROPICAL WAVE EAST OF THE WINDWARD ISLANDS SHOULD BE EXPECTED WEDNESDAY INTO THURSDAY BRINGING ACTIVE WEATHER FOR THE U.S. VIRGIN ISLANDS AND PUERTO RICO. && .MARINE... WINDS ARE INCREASING ACROSS THE LOCAL AREA AS THE WAVE PROGRESSES. 88D VAD DEPICTING 20 KTS. NAVY WAVE MODEL MAINTAINING 6-8 FEET SEAS ACROSS ATLANTIC AND CARIBBEAN WATERS THROUGH WEDNESDAY..SITUATION WHICH WAS HANDLE WELL BY PREVIOUS FORECAST. MAIN CONCERN ARE THE GUSTY WINDS AT 30 KTS ASSOCIATED WITH THE SHOWERS AND THUNDERSTORMS SURROUNDING THE LOCAL WATERS. SMALL CRAFT ADVISORIES ARE IN PLACE. && .AVIATION... ACTIVE WEATHER TODAY AS THE WAVE CONTINUES ITS WESTWARD TRACK. FROM DOMINICAN REPUBLIC TO CENTRAL PUERTO RICO WEATHER CONDITIONS WILL DETERIORATE DURING THE MORNING WITH SHOWERS AND THUNDERSTORMS BECOMING MORE WIDESPREAD OVERLAND BY AFTERNOON WITH CEILINGS AND VISIBILITIES OCCASIONALLY BELOW 1 THOUSAND FEET AND 3 MILES. SAHARAN DUST SHOULD WORKED ITS WAY IN AS THE SUBSIDENCE SETS BEHIND THE WAVE TONIGHT INTO TUESDAY. && .HYDROLOGY... RIVERS LEVELS SO FAR WITHIN NORMAL RANGE. SHOWERS AND THUNDERSTORMS MOVING WEST AT LEAST AT 20 KTS WHICH IS NOT IDEAL FOR FLASH FLOODING. HOWEVER...ONCE THE WAVE AXIS MOVES OVER THE MONA PASSAGE THE SOUTHEAST FLOW IN THE LOW LEVELS WILL CONTINUE TO ADVECT SHOWERS AND THUNDERSTORMS ACROSS THE EAST AND SOUTHEAST AND IS SPITE OF THE FAST MOTION...TRAIN ECHO EFFECTS WILL CAUSE LOCALIZED HEAVY RAINFALL THAT COULD INDUCE SMALL STREAM AND URBAN FLOODING. SO FAR RAINFALL AMOUNTS OVER LAND THROUGH 330 AM LESS THAN ONE INCH...BUT THIS SCENARIO COULD CHANGE AS ADDITIONAL BANDS OF SHOWERS AND THUNDERSTORMS MOVE OVER THE EASTERN HALF OF THE ISLAND. FOR THE U.S VIRGIN ISLANDS URBAN AND SMALL STREAM FLOODING WITH SOME OF THE HEAVIER SHOWERS. USGS GAGES SHOWED AMOUNTS OF LESS THAN A QUARTER OF AN INCH SO FAR. && .PRELIMINARY POINT TEMPS/POPS...
