...WIND ADVISORY IN EFFECT FROM 9 AM THIS MORNING TO 6 PM CST
THIS EVENING...

The National Weather Service in Saint Louis has issued a Wind
Advisory, which is in effect from 9 AM this morning to 6 PM CST
this evening.

* TIMING...Strong gusty winds will already be developing by mid-
  morning for portions of central Missouri and will quickly spread
  southeastward into southeast Missouri during late morning. These
  strong gusty winds will continue until near sunset. 

* WINDS...West 15 to 30 mph with gusts up to 45 mph.

* IMPACTS...Winds this strong can make driving difficult,
  especially for high profile vehicles on north-south oriented 
  roads and highways. These winds can also lift and move trash 
  cans, lawn furniture, and other loose outdoor objects. Minor 
  tree and building damage is also possible. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Wind Advisory is issued when sustained winds are forecast to be
30 to 39 mph or gusts will range between 45 and 57 mph. Winds of
these magnitudes may cause minor property damage without extra
precautions. Motorists in high profile vehicles should use
caution until the winds diminish.
