Environment Canada forecast script (for www.weatheroffice.gc.ca)

This script is along the lines of the carterlake.org NOAA 5-day script especially for the Canadian stations using Environment Canada as the source of the data. It uses a new set of customized icons with PoP displayed like the www.crh.noaa.gov website used by Tom's script. Examples:

Partly Cloudy PoP: 40% ==> Partly Cloudy
Rain and snow PoP: 100% ==> Rain and snow
Thunderstorm PoP: 70% ==> Thunderstorm

To use it, you need to download the ec-forecast-V2-10.zip file and unzip, then upload to your website. The scripts and icons are included in the zip file. The script also requires the URL for the printable forecast for your area. Instructions are included with the source file and the ec-forecast-README.txt for the script.

The script supports both English and French languages via the lang=en or lang=fr parameter. A live example of the French version (with lang=fr) is shown below.

Environment Canada

With Version 1.08, a new $currentConditions string is formatted with the current conditions of the selected city. If the city's conditions are based on a nearby airport, then a current conditions icon and short weather description are included. You can enable automatic printout by using $showConditions = true; in the ec-forecast.php script which will cause it to print before the alerts and forecast section. If you're 'quitely' including the script on your page, you can still print $currentConditions; where you'd like the conditions display to appear.

Version 2.00 brings a major rewrite of the script to accomodate a major change in the EC Forecast pages. Included with the .ZIP distribution are the new icons now in use by EC for the forecast site. The V2.00 script is compatible with the prior icon set distributed with the Version 1.nn script.

You can also access the 'normal temperatures' for the location (where available on the EC site) by using

 <?php
print "Normal for this date:<br/>\n";
print $conditions['normsmaxtemp'] . "<br/>\n";
print $conditions['normsmintemp'] . "\n";
?>

which would show:

Normal for this date:
Max: 5°C
Min: -5°C
