For the basic radar and home-page images, edit Settings.php and change
// Radar settings
$SITE['noaaradar'] = 'MUX'; // LAST 3 characters of NOAA Radar Site ID
// e.g. Radar KMUX has $SITE['noaaradar'] = 'MUX';
$SITE['WUregion'] = 'sw'; // Wunderground regional maps
// 'sw'=SouthWest, 'nw'=NorthWest, 'mw'=Midwest
// 'sp'=South Central, 'ne'=North East, 'se'=South East
to
// Radar settings
$SITE['noaaradar'] = 'RTX'; // LAST 3 characters of NOAA Radar Site ID
// e.g. Radar KMUX has $SITE['noaaradar'] = 'MUX';
$SITE['WUregion'] = 'nw'; // Wunderground regional maps
// 'sw'=SouthWest, 'nw'=NorthWest, 'mw'=Midwest
// 'sp'=South Central, 'ne'=North East, 'se'=South East
I see you’ve changed your NWS forecast/alerts settings to
$SITE['NWSforecasts'] = array( // for the advforecast2.php V3.xx version script
// use "Zone|Location|Point-printableURL", as entries .. first one will be the default forecast.
"ORC051|Portland|https://forecast.weather.gov/MapClick.php?lat=45.534&lon=-122.8189&unit=0&lg=english&FcstType=text&TextType=2",
"ORC067|Cedar Hills|https://forecast.weather.gov/MapClick.php?lat=45.4847&lon=-122.796&unit=0&lg=english&FcstType=text&TextType=2",
);
// Uncomment the two lines below to use WXSIM as the ONLY forecast script to use
// $SITE['fcstscript'] = 'plaintext-parser.php'; // WXSIM forecast (if only forecast script)
// $SITE['fcstorg'] = 'WXSIM'; // set to 'WXSIM' for WXSIM forecast
// NOAA warning zone
$SITE['noaazone'] = 'ORC067'; // used for NOAA advisories and advforecast2.php zone forecasts
$SITE['hurlURL'] = "wxadvisory.php"; // page to launch for details on NOAA advisories
//
// NWS Alerts package configuration (for Curly's nws-alerts scripts)
// "Location|ZoneCode|CountyCode[|CountyCode]..."
// Note: if more than 4 zone/county codes are used, a message will appear if you are NOT using
// cron to provide updates.
// Note: additional/optional nws-alerts configuration is in nws-alerts-config.php file
$SITE['NWSalertsCodes'] = array(
"Santa Clara Valley|CAZ513|CAC085",
// "Santa Cruz Mtns|CAZ512|CAC081|CAC085|CAC087",
"Santa Cruz|CAZ529|CAC087",
// "Monterey|CAZ530|CAC053",
// "South/East Bay|CAZ508|CAC081",
// "San Mateo Coast|CAZ509|CAC081",
// "San Francisco|CAZ006|CAC075"
);
For forecasts, you need to use the Forecast Zone code, not the County Code. Both the Forecast Zone and County Zone should appear in the NWSalerts area however.
I suggest you replace the above with
$SITE['NWSforecasts'] = array( // for the advforecast2.php V3.xx version script
// use "Zone|Location|Point-printableURL", as entries .. first one will be the default forecast.
"ORZ006|Portland|https://forecast.weather.gov/MapClick.php?lat=45.534&lon=-122.8189&unit=0&lg=english&FcstType=text&TextType=2",
"ORZ006|Cedar Hills|https://forecast.weather.gov/MapClick.php?lat=45.4847&lon=-122.796&unit=0&lg=english&FcstType=text&TextType=2",
);
// Uncomment the two lines below to use WXSIM as the ONLY forecast script to use
// $SITE['fcstscript'] = 'plaintext-parser.php'; // WXSIM forecast (if only forecast script)
// $SITE['fcstorg'] = 'WXSIM'; // set to 'WXSIM' for WXSIM forecast
// NOAA warning zone
$SITE['noaazone'] = 'ORZ006'; // used for NOAA advisories and advforecast2.php zone forecasts
$SITE['hurlURL'] = "wxadvisory.php"; // page to launch for details on NOAA advisories
//
// NWS Alerts package configuration (for Curly's nws-alerts scripts)
// "Location|ZoneCode|CountyCode[|CountyCode]..."
// Note: if more than 4 zone/county codes are used, a message will appear if you are NOT using
// cron to provide updates.
// Note: additional/optional nws-alerts configuration is in nws-alerts-config.php file
$SITE['NWSalertsCodes'] = array(
"Portland|ORZ006|ORC067",
// "Santa Cruz Mtns|CAZ512|CAC081|CAC085|CAC087",
// "Santa Cruz|CAZ529|CAC087",
// "Monterey|CAZ530|CAC053",
// "South/East Bay|CAZ508|CAC081",
// "San Mateo Coast|CAZ509|CAC081",
// "San Francisco|CAZ006|CAC075"
);
and that should correct both issues.
