National Weather Service alerts map for your zone/county. The color key table only shows the keys for alerts that are active in your specified county or zone and only shows one alert for each spot on the map, even when more than one alert may be active at that spot. According to the NWS, when there are multiple alerts for a single spot, 'only the most significant threat to life or property is displayed on the map.'

This system is powered by the open source WeeWX package, authored by Tom Keffer.

This system uses the open source Purple Air extensions to WeeWX package by Kenneth Baker to obtain the raw air pollutant values.

Thanks to JaneAndJohn.org for PHP-based RSS weather-feed code used in a prior iteration of this site.

Thanks to Ken True at Saratoga-Weather.org for pointers to good warning scripts, used in a prior iteration, and for being a great overall resource for scripting weather websites. Also, the idea to ignore certificate errors from the NOAA/NWS website comes from these scripts.

Thanks to Ken True at Saratoga-Weather.org and Mike Chaliss for their alerts script from which we leverage the array mapping alert event name to alert event background color, and a clever way to handle events that aren't in that mapping.

Thanks to Tom at carterlake.org for a script that caused me to want to learn how to obtain the raw data of a National Weather Service forecast, that triggered my building my own set of scripts. He has also created another great overall resource for scripting weather websites.

The raw data on which the forecasts are built, and the icons for these, come from the National Weather Service.

This system utilizes the xmlize utility written by Hans Anderson.

The URL used to get the alerts, and the idea to use cURL to get them (and any other needed JSON/XML data), comes from the "NWS Alerts" PHP package by Rick "Curly" at the WXForum web site.

The idea to use and how to properly invoke the xmlize library to extract information from the NWS comes from PXWeather by Jonathan M. Abbett.

The algorithms used to either adjust the Purpleair sensor PM2.5 pollutant concentrations or to convert from PM2.5 pollutant concentrations to an AQI value come from multiple sources.

If you want a copy of the current code that produces this generated-forecast information, and performs AQI calculations, as well as more open source license information for this package and the ones that it uses or has learned from, click here.
