I am using Google Maps to display radar and weather alert data from NWS. I have had difficulty displaying the latest polygonal alert data.

I am able to get the latest file by manually modifying the query string each time I want to update the KMZ polygons.

How can I include scripting to modify the end string of the KMZ filename within my Google Maps script, so that I obtain a fresh copy of the latest polygonal alert data each time the site is visited?

var ctaLayer

ctaLayer = new google.maps.KmlLayer({
 url:'https://www.spc.noaa.gov/products/watch/ActiveWW.kmz?=dummy5',  
 preserveViewport:true, 
 suppressInfoWindows:false, 
 map:map,
 });
