As of Dec. 15, 2011 the OTTAWA MACDONALD-CARTIER INT’L A and HAMILTON A weather reporting stations have switched over to new NAV CANADA sensors and reporting tools. Due to a new format, hourly data from these stations is not yet available on our website. If you are interested in daily data for these stations from Dec 15, 2011 forward, they can now be found under their new weather station names, OTTAWA INT’L and HAMILTON. For more information, please click here and expand the message. Thank you for your patience while we work to upgrade our system to display these data.
We are currently experiencing some problems with the French version of the Climate Summaries on our Products & Services page. We are working to rectify the problem and ask for your patience during this time of technical difficulty. In the meantime, please refer to the data available from the English Climate Summaries page.
The Notice Inventory contains a record of all past and current Notices.
