Weather & Information Images (WX-IMG)

Sunday, December 27th, 2009

I have updated my WX-IMG products and have included the WWV image in this release.
To add these images to your site please see http://www.w8jkc.com/copythis.php?q=1
You are free to add them to your website, Facebook, MySpace or similar profile, including web signatures.

Also included in this release is my simple email address spam blocking image script. It is very simple to add to any page, but requires basic knowledge of HTTP URL structures. However it is explained completely on the page linked above.

I have changed the methodology behind the Weather Spotter Image too, it used to refresh the data every time the image was accessed or loaded, which means every time somebody viewed a page that had that image in it, the information would be retrieved again. This works great, however now that more people are using that image I am using way too much bandwidth and I am sure the NWS and NOAA did not appreciate me requesting the information so many times. This is especially true because they usually only update the information once every 24 hours (around 6am). I have changed this to only request and update every 7 hours, which means 3 updates per day. Currently the update times are (EDT) 0700, 01400, and 2300hrs each day. I believe this is the most effective use, because we have had some afternoon and some evening storms.

Weather Alerts

Tuesday, August 18th, 2009

I have setup a new custom Weather Alert and SkyWarn Spotter Activation script through PHP and Twitter for Stark County, Ohio.

This project is currently in Live Beta Testing and I am encouraging anyone to “follow” the account; and if you wish, have them text messaged to your phone.

For now, this script will tweet any time someone views either of my WX-IMG for Stark County, which are currently used on many different websites.

This script will alert under any of the following conditions:

  • Flood Warning
  • High Wind Warning
  • High Wind Watch
  • Flood Watch
  • Tornado Watch
  • Tornado Warning
  • Severe Thunderstorm Warning
  • Severe Thunderstorm Watch
  • Frost Advisory
  • Freeze Warning
  • Wind Warning
  • Wind Advisory
  • Wind Chill Advisory
  • Blizzard Watch
  • Blizzard Warning
  • Winter Storm Watch
  • Winter Storm Warning
  • Winter Weather Advisory
  • Any “Special” Advisory
  • Spotters are encouraged to report
  • Spotter Activation is expected
  • Spotters have been activated
  • Spotter Activation may be needed
  • Spotter Activation will likely be needed
  • Spotter activation is possible on “day”

“Day” meaning one of: Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, or Friday.

I plan to integrate this with my WX-IMG and WX-JS projects on a new project/website called WX-W8JKC which can be found in the near future at http://wx.w8jkc.com

I also plan on setting it up to check for Weather Alerts every 5 minutes and Spotter Activation every 2 hours, This will help to make it more reliable and help to prevent spam tweets with the same message.

The URL for this new Twitter account is http://www.twitter.com/starkohiowx

WX-JS Officially Released

Thursday, October 9th, 2008

I am now officially releasing WX-JS, a free project that allows you to add dynamic Weather Alerts to your website through a simple javascript code.

This project coincides with my WX-IMG project, and uses the same data from an RSS feed over at weather.gov, which is updated about every 5 minutes.

Currently, these scripts grab the feed from weather.gov everytime the script is accessed, and the more people who use these projects, the more bandwidth it will use from my ISP, and to weather.gov

The next version of these projects will include a 5 minute server side cache of the data from the weather.gov feed, and will tell the browser to cache the image or data for same expire time as the feed cache.

This will allow more people to use my script, with less server load on my end, along with bandwidth to me and to weather.gov
