..NWS DAMAGE SURVEY FOR 06/25/25 TORNADO EVENT
OVERVIEW
ON JUNE 25TH 2025, STRONG THUNDERSTORMS DEVELOPED OVER PINELLAS
COUNTY AS THE EAST AND WEST COAST SEA BREEZE BOUNDARIES COLLIDED.
THESE THUNDERSTORMS WERE FURTHER ENHANCED BY A STRONG UPPER-LEVEL
LOW OVER THE STATE, LEADING TO COLDER AND DRIER AIR ALOFT THAT
ENHANCED THE POTENTIAL FOR DAMAGING WIND GUSTS AND HAIL. WHILE
NUMEROUS HAIL AND WIND DAMAGE REPORTS WERE RECEIVED FROM ST.
PETERSBURG TO SEMINOLE, A LANDSPOUT ALSO DEVELOPED IN LARGO, FL,
ALONG COLLIDING SEA BREEZE AND OUTFLOW BOUNDARIES.
THE SETUP LEADING TO THE LANDSPOUT'S DEVELOPMENT WAS COMPLEX. TWO
BOUNDARIES COLLIDED OVER LARGO - ONE FROM A STRONG CELL TO THE SW
AND ONE FROM ANOTHER STRONG CELL TO THE EAST. AS THESE BOUNDARIES
COLLIDED, A NEW UPDRAFT BEGAN TO DEVELOP WHERE THE COLLISION TOOK
PLACE. STRONG DOWNDRAFTS FROM BOTH CELLS ESSENTIALLY SANDWICHED THE
BOUNDARY AND THE DEVELOPING UPDRAFT BETWEEN THE MORE MATURE CELLS -
FORCING THE DEVELOPING CELL TO TAKE A DEVIANT TRACK TO THE NORTH,
RIGHT ALONG THE BOUNDARY COLLISION. THIS CAUSED THE CELL TO BEGIN
ROTATING.
AT APPROXIMATELY 6:57PM EDT, THE TTPA TDWR OBSERVED ROTATION JUST
SOUTH OF BELCHER RD NEAR THE INTERSECTION WITH BRYAN DAIRY RD.
REFLECTIVITY DATA AT THE SAME TIME SHOWED ALMOST NO PRECIPITATION ON
THE 0.3 DEGREE SLICE, BUT A STILL-SUSPENDED AND DEVELOPING CORE
ALOFT AT HIGHER TILTS. THE ROTATION WAS NOT DISTINGUISHABLE ON THE
KTBW RADAR, GIVEN THE DEVELOPING CELL'S MOTION WITH RESPECT TO THE
BEAM ANGLE. ULTIMATELY, THE ANGLE MASKED THE ACTUAL STORM-RELATIVE
VELOCITY. OVER THE NEXT COUPLE MINUTES, THE ROTATION INTENSIFIED AND
AT 7:02PM, THE FIRST DAMAGE OCCURRED AT A SHOPPING CENTER NEAR THE
AFOREMENTIONED INTERSECTION. OVER THE NEXT EIGHT MINUTES, ADDITIONAL
DAMAGE REPORTS WERE RECEIVED ALONG A TRACK ORIENTED SSW TO NNE. THE
MOST SIGNIFICANT DAMAGE WAS NOTED IN THE RANCHERO VILLAGE
COMMUNITY, WHERE SEVERAL MOBILE/MANUFACTURED STRUCTURES WERE BADLY
DAMAGED, INDICATING A PEAK INTENSITY OF AROUND 90 MPH.
AT 7:10PM, THE LANDSPOUT DISSIPATED AS THE TTPA TDWR DATA SHOWS THE
MESOCYCLONE WEAKENING. THIS TOOK PLACE AS A GUST FRONT FROM ANOTHER
MATURE CELL TO THE EAST ARRIVED, ALTERING THE ABILITY FOR THE
DEVELOPING CELL TO REMAIN ON THE BOUNDARY THAT WAS ALLOWING IT TO
SPIN. IN TOTAL, THE FEATURE WAS TRACKED FOR JUST OVER 2 MILES AND
HAD A MAXIMUM WIDTH OF 100 YARDS.
