Does the array in Settings.php match the array in the file nws-alerts-config.php?
This is in the nws-alerts-config.php file:
$myZC = array(
"Phoenix|AZZ023|AZC013",
"Apache County|AZZ014|AZZ114|AZC001",
"Cochise County|AZZ508|AZC003",
"Coconino County|AZZ007|AZC005",
"Gila County|AZZ018|AZZ024|AZC007",
"Graham County|AZC009",
"Greenlee County|AZZ510|AZC011",
"La Paz County|AZC012",
"Maricopa County|AZZ022|AZZ027|AZC013",
"Mohave County|AZZ002|AZC015",
"Navaho County|AZZ113|AZC017",
"Pima County|AZZ501|AZC019",
"Pinal County|AZZ028|AZC021",
"Santa Cruz County|AZC023",
"Yavapai County|AZZ037|AZZ108|AZC025",
"Yuma County|AZZ025|AZZ131|AZC027"
);
Having $locSort set at 0, it will list Phoenix first unless you change $locSort to 1.
$locSort = 0; // location name sort - use number listed below
// 0 = sort location as listed in $myZC array
// 1 = sort location alphabetically
