 Special Weather Statement  Statement as of 1:48 PM CDT on July 30, 2010


... Ozone watch issued on Saturday...

The Texas commission on environmental quality... has issued an
ozone watch for the Houston... Galveston... and Brazoria areas for
Saturday... July 31. Atmospheric conditions are expected to be
favorable for producing high levels of ozone pollution in the
Houston... Galveston... and Brazoria areas.

Elevated concentrations of ozone can act as a lung irritant.
Individuals with chronic lung disease... such as asthma and
emphysema... and the elderly and small children... are particularly
sensitive to ozone and should attempt to avoid exposure. To avoid
exposure... minimize exertion outdoors during the mid-day to early
evening hours or stay indoors in an air conditioned area during this
time.

Ozone reaching excessive levels at any site in the area may move to
or from other sites within the area... depending on wind direction and
other factors. Excessive levels may linger until sunset. Ozone
warnings will be issued if air pollution levels are detected at
unhealthy levels.
