The National Weather Service in Shreveport has issued a Lake Wind Advisory from 10 am this morning until 6 PM this evening.
* Event... strong southwest winds near 20 mph with gusts to 35 mph.

A high wind advisory is issued when sustained winds of 31 mph or greater are expected to occur for at least 1 hour. This advisory can also be issued if winds of 46 mph or greater are expected for any length of time.

The severe overlay on Local Radar from WU shows a dark turquoise color for the High Wind Advisory label. Wind advisories are "site specific" according to the NOAA glossary for the NWS. Evidently, 20 mph sustained winds and 35 mph gusts qualify for the High Wind package as well even though the Shreveport gusts listed in the Event above are not sustained, nor are 20mph winds a qualifier. There is a widespread advisory as you see, with all the dark turquoise counties on the the map below.

I am trying to understand if my incorrect issuance of a High Wind Advisory Jan 20th was wrong now!



There has been widespread fog locally since 3 AM. You can see the foggy locations here marked with the pink = (equals signs).
