Line Configurations

AVOID THUNDERSTORM ECHOES AT THE SOUTH END OF A
LINE OR AT A BREAK IN A LINE BY 20 MILES
The echo at the south end of a line of echoes is often severe and so too
is the storm on the north side of a break in line. Breaks frequently fill in
and are particularly hazardous for this reason. Breaks should be
avoided unless they are 40 miles wide. This is usually enough room to
avoid thunderstorm hazards.
The above two locations favor severe thunderstorm formation since
these storms have less competition for low level moisture than others
nearby.
