The present season appears to be par
ticularly favorable to the development
of tornadoes, according to
Tornado our experts at the United
States weather bureau. and
oeoSoA' they are sending warnings
to every part of the country.
Persons may somewhat avoid tornado
danger, it is pointed out, by watching
the local signs and reading che weather
maps, which at least show the condi-
tions which favor tornado formation.

diately followed by clouds in the north
west and north. A funnel-shaped cloud
is sure sign. though there may be
tornado when such a cloud is not
readily seen.
Weather men define a tornado as a
violent windstorm with rain or hail,
thunder and lightning. in which the air
masses whirl with great velocity
around central core. while the whole
storm travels across the country in a
narrow path at high speed.
A cyclone. in the definition of the
weather bureau. is not necessarily a
windstorm of great velocity but ra ather
a widespread storm that moves with no
great speed Its width may cover
several states.
nadoes are usually preceded by high
temperature and humidity weather
condition generally said to be "sultry."
sticky or Oppressive" Rain may
come before, with or after a tornado
or. very rarely, there may be no rain
at all. The barometer does not fore
tell tornado. though 1t indicates low
pressures, and tornadoes always occur
in q low area.
Giving advice to those who inhabit
tornado-infested districts. the bureau
officials say that brick buildings are
not very safe. but the cellar is probably
the safest place in them. In the Omaha
tornado of 1913 very few brick houses.

some of the plains states there are so
