KMZ seems to be A zip archive of XML file(s) plus others. For instance "AL052019_041adv_TRACK.kmz" has "AL052019_041adv_TRACK.kml" in it plus all the icons they use. In windows can change the .kmz to .zip and open it. The Microsoft office format (docx, pptx, or xlsx) is also like this.

To get the NHC kmz's, get https://www.nhc.noaa.gov/gis/kml/nhc_active.kml It has the links to other current products in .kmz, and other info. A cron job on an OpenWRT router could easily serve/archive current products with wget/curl and xsltproc.

@connorbias Good simple example which got me started, as I am not familiar with KML. Was able to produce what I wanted starting with this.

Offloaded getting the past track from NHC to a wi-fi hotpoint (Cisco Meraki MR-24/OpenWRT). A 4 line shell script gets (curl) www.nhc.noaa.gov/gis/kml/nhc_active.kml, and runs it through xsltproc against 35 lines of XSLT to parse and generate a script which gets the current .kml's (and converts from .kmz).

@madjidt Had to modify XSLT stylesheet doing the conversion to clean up what Windy does not like. Sometimes the source data is not clean. The stylesheet is applied to an XML file containing source file names to obtain, icon substitution, bounding box, data select filter. XSLT xsl:document () does the downloading. Trying to get to no-touch operation.
