Dense Fog Advisory
Statement as of 3:05 am CST on November 22, 2009

... Dense fog advisory in effect until 10 am CST this morning...

The National Weather Service in Austin/San Antonio has issued a
dense fog advisory... which is in effect until 10 am CST this
morning.

Wet grounds... light winds... and dry air aloft has enabled
widespread fog to develop across south central Texas this morning.
Visibilities will lower to one quarter of a mile or less across
the region... especially in the near-sunrise hours. The fog is
expected to gradually lift and dissipate through mid-morning.

Precautionary/preparedness actions...

A dense fog advisory means visibilities will frequently be
reduced to less than one quarter mile. If driving... slow down...
use your headlights... and leave plenty of distance ahead of you.
