Fire weather/fire prevention awareness week concludes today with
a look at our primary and secondary fire weather seasons.
As mentioned previously... low relative humidities and high wind
speeds are two key ingredients which act to increase the degree of
fire danger. These two weather ingredients combined with drier
vegetation are most prevalent during the primary and secondary
fire weather seasons.
The primary fire weather season occurs in the fall. It runs from
October 1st until Dec 15th. Climatologically for Tennessee... the
months which lead into the primary season... September and
October... are generally the driest months of the year. During this
time of year temperatures are cooling off. This serves to reduce the
threat of heavier showers and thunderstorms which are usually
driven by warmer surface temperatures. Also... the jet
stream... where the better organized weather systems reside... is
located well north of Tennessee.
Typically... in the month of September... the vegetation begins to dry
out. By October... a combination of drier vegetation and the end of
the growing season could lead to an extended period of higher fire
Climatological records for Nashville indicate that the driest months
of the year on record generally occurred in September and October.
In fact... records indicate that an average of only .20 inches or
less of rain fell during these record breaking months.
The secondary fire weather season occurs in the late winter and
early Spring. It begins on February 15th and lasts until may 1st. As
we get into late February and March... most of the vegetation is still
dormant and temperatures are beginning to warm. The warmer
temperatures serve to increase the surface evaporation rate
thereby keeping the vegetation rather dry. Furthermore... it is now
close to Kite flying weather and soon the March winds will begin to
blow. With these ingredients in place... elevated levels of fire
danger can occur.
In conclusion... though we have discussed the seasonal impacts of
weather on fires... keep in mind that fires can occur at any time of
the year. We should always strive to stay educated. But most
importantly... be careful and play by the rules.
