...STRONG AND GUSTY SOUTH WINDS EXPECTED THIS AFTERNOON...

.A tight gradient between surface high pressure east of Florida 
and an area of low pressure and associated cold front moving
through the Southern Plains will result in increasing south winds
this afternoon. In addition, a belt of strong winds within a few
thousand feet of the surface will result in gusts occasionally 
reaching 35 to 40 mph, especially over the coastal counties and
parishes. Winds are expected to subside early this evening, but 
could remain elevated near the immediate coast through mid
evening.
