Dense Fog Advisory
Statement as of 8:56 PM CST on November 22, 2009

... Dense fog advisory in effect from midnight tonight to 9 am CST
Monday...

The National Weather Service in Houston/Galveston has issued a
dense fog advisory... which is in effect from midnight tonight to
9 am CST Monday.

Clear skies tonight with calm winds will lead to the formation of
fog overnight. Moisture from the recent rainfall will keep the
surface moist allowing for fog to develop as the temperature
drops into the 40s overnight. Visibility will be reduced to a
quarter mile or less across southeast Texas.

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.
