| This series of images shows the progress of the tornado
through the Fallbrook area at 9:20am on February 19th, as captured
by doppler radar near Poway
in San Diego County, which measures reflectivity.
These images represent four different elevations from the horizon
(from the top left,
0.5 degrees, 1.5 degrees, 2.5 degrees and 3.5 degrees going clockwise).
The red curl in the top left photo is a hook
echo commonly associated with storms that may have tornado potential.
