	I am a trained Skywarn spotter for the National Weather Service (NWS). See http://www.nws.noaa.gov/skywarn/ for more information.		I am a trained Skywarn spotter for the National Weather Service.

			National Weather Service (NWS) spotters are civilian volunteers who, after taking an online or onsite training course conducted by the NWS (there is a Basic level and an Advances level course sometimes taken together on the same day. Each course is typically three to four hours long) are authorized to report their weather observations directly to the NWS (using a special telephone number or sometimes via ham radio), especially during particularly bad weather conditions. Many times, the fact that something like a tornado has actually formed and touched the ground is first reported to the NWS by trained weather spotters.

			See http://www.nws.noaa.gov/skywarn/ for more information.

	===Spotter information statement===		===Spotter information statement===

	~~For a~~ Skywarn spotter to be ~~aware they may~~ be ~~requested~~ the NWS		Skywarn spotters sometimes are requested the NWS to monitor weather conditions if bad weather is anticipated. This is referred to as "spotter activation".

			Weather spotter activation means that the NWS is monitoring weather conditions in a particular area and they want trained spotters to be on the alert for monitoring and reporting adverse weather conditions. This is because, with all the instrumentation available to NWS personnel, sometimes the best indications of current severe weather conditions are from people on the ground actually observing these conditions.

			To know if your particular area will be requesting activation a bulletin is put out at least daily and often updated throughout the day referred to as the "Hazard Weather Outlook". A sample of one is found at https://www.weather.gov/mfl/ghwo. See also https://en.wikipedia.org/wiki/Hazardous_weather_outlook Hazardous Weather Outlook.

			The HWO product from the NWS is usually only published to the public via the NWS various web sites. Sometimes it is available via FTP access and some weather forecast offices (WFO) will email the daily HWO bulletin to registered trained spotters.

			Even if you are not a trained spotter it is still good to know the hazardous outlook of the area where you will be that day.

			The part of the HWO that indicates if Skywarn activation is in a block of text titled ".SPOTTER INFORMATION STATEMENT...".

			Since my local office does not provide the daily email of the HWO I wanted a way to get a daily email to know if activation was likely that day. A long time ago I used to send this to a text pager I carried.

			===Script===

	~~Here is~~ a ~~script I use~~ to alert me on days that spotter activation may be required based on the NWS HWO product for my forecast office (WFO or WSFO).		To that end I wrote a Python 3 to alert me on days that spotter activation may be required based on the NWS HWO product for my forecast office (WFO or WSFO).

In it is always~~ a ~~mention of Skywarn Spotter activation~~.		I have found the text HWO product to be reliably available via a properly formatted URL.

	~~Even if you are not a trained spotter it is still good to know the outlook of the area where you will be that day. I travel fairly enough and visit relatives across several geographical areas.~~ I can modify my script on a given day to include additional forecasts by the local WFO when I am traveling.
