CANADIAN APRS WEATHER PROJECT
Project Definition
This project will provide Radio Amateurs with official Environment Canada
notification of severe weather. APRS Stations will then "relay" the
data to the APRS Network. In doing so, they can provide an additional
service to the general public, the communities they serve (ARES) and it can
also be used by Canwarn, as a secondary method of communications. During
network conditions yellow and red, it would be very useful to the Canwarn
Network Controller to know exactly where Canwarn stations (identified by
an eyeball icon) are located in relationship to a storm's radar image.
Specific weather information could then be acquired / exchanged, using either
the voice network, APRS messaging, or APRS weather observations may be read
direct from the station weather instruments. While radio amateurs are
already sharing weather reports and notifications on APRS, this project would
be such that only official E.C. information would be released.
The first phase of this project is to manually send the information to APRS.
The second phase would be to connect with E.C. via the Internet, and automate
the process. That would allow E.C. complete control of the notification.
Graphic data indicating affected weather areas would be relayed from
E.C. to the APRS Network across Canada, or to specific locations served by
APRS Stations.
Any APRS equipped station can receive these broadcasts. Currently,
in southern Ontario, about 200 radio amateur stations are using APRS at any
time of the day.

The following images are intended to demonstrate the adage "A picture
is worth a thousand words." If you don't have a high speed connection,
it would be ok to slip out and open an 807, soft drink, or brew a coffee.
Sorry, but I wanted you to see APRS quality images.
This is a Buffalo NY - Long Range Radar image indicating storm conditions. APRS Stations have been removed for clarity.
The yellow
dashed line is the standard for a Thunderstorm
Watch
Condition. It has been drawn and published to the APRS Network by
VA3LKI, an APRS station. An automated process would see duplications
of Environment Canada graphics superimposed on the map graphic.
If a
weather warning (Thunderstorm / Tornado) were to be issued within these boundaries, a separate area would be designated - a
solid yellow line for the Thunderstorm
Warning, and a
solid red line for a Tornado
Warning.
This is the same Buffalo NY - Long Range Radar image with selected APRS Stations being shown for clarity.
Note the Area Object icon for a Thunderstorm and the description of WX WATCH.
It has been published to the APRS Network by an APRS station.
This is the Buffalo NY - Short Range Radar image with selected APRS Stations being shown for clarity.
Note the Area Object icon for a Thunderstorm and the description of WX WATCH.
It has been published to the APRS Network by an APRS station.
This is the another Buffalo NY - Short Range Radar image (a short time later)
with all APRS Stations that were in range of the receiving station (VA3LKI)
at time of image capture. It does not represent all of the stations in the APRS Network.
This is the King ON Radar image indicating storm conditions. APRS Stations have been removed for clarity.
The yellow dashed lined is the standard for a Thunderstorm Watch Condition.
It has been drawn and published to the APRS Network by an APRS station.
This is the King ON Radar image indicating storm conditions. Some APRS Stations have been inserted for reference.
This is a political map showing portions of South / Central Ontario, East
Michigan, Ohio and NY. The boundary indicates a Thunderstorm Watch
Area.

The following maps do not do justice to their potential, and will be very
useful during winter weather conditions. When the road condition data
is published, APRS users will be able to see the winter weather impact on
road conditions relative to station locations. This will be tested further later in the year.
This image shows a portion of a Weather Watch boundary. In winter it
is likely to be relative to severe snow storm or blizzard conditions.
The icon that will accompany the WX WATCH will indicate the type of watch condition.
The same image with APRS Stations for reference.
