...SUMMARY...
BASED ON ADDITIONAL INFORMATION PROVIDED BY TV METEOROLOGISTS, 
RESIDENTS, AND SKYWARN AMATEUR RADIO, THE NATIONAL WEATHER SERVICE 
HAS DETERMINED THAT THERE WAS AN ADDITIONAL TORNADO IN WEST 
YARMOUTH ON JULY 23. THIS BRIEF AND NARROW TORNADO WAS ON THE 
GROUND AT THE SAME TIME AS ANOTHER TORNADO...PREVIOUSLY DOCUMENTED
...WAS MOVING TOWARD SOUTH YARMOUTH.

THE TORNADO TOUCHED DOWN ON YACHT AVENUE AND SCHOONER STREET IN 
WEST YARMOUTH AND TRAVELED EAST APPROXIMATELY ONE-QUARTER MILE
BEFORE LIFTING ON EGG HARBOR ROAD MANY THANKS AGAIN, ESPECIALLY TO 
JUST AFTER PINE CONE DRIVE. THE PATH WIDTH WAS APPROXIMATELY 50 YARDS. 
NUMEROUS PINE TREES WERE SNAPPED NEAR THEIR BASES. TREE TOPS 
APPEARED TWISTED. RESIDENTS REPORTED SEEING SWIRLING MOTION. 
NWS DOPPLER RADAR SHOWED A TORNADO DEBRIS SIGNATURE WITH THIS STORM, 
INDICATING THAT SOME TREES AND BRANCHES WERE LOFTED INTO THE AIR. 
THIS TORNADO WAS ONLY ON THE GROUND FOR ONE MINUTE, BETWEEN NOON

RIVER.

STRAIGHT LINE DOWNBURST WINDS.
