THE METEOROLOGICAL SERVICE OF CANADA. 



Reports have been received at the Central Office from 650 stations, 

 including telegraph reporting stations, climatological and storm signal 

 stations. 



Forecasts and Storm Warnings: — ^Bi-daily synchronous weather 

 charts have been compiled on every day throughout the year, Sundays 

 and holidays included, based on telegraphic reports from 38 stations in 

 Canada, 100 in the United States, 4 in Newfoundland and 1 in Ber- 

 muda. Three of our most useful stations, Sable Island and Belle 

 Isle in the Atlantic and Triangle Island in the Pacific, ceased reporting 

 by wireless at the outbreak of the War. These charts have formed the 

 basis of the forecasts and storm warnings which have been issued from 

 Toronto for all the provinces, exclusive of British Columbia, where 

 at Victoria a somewhat less comprehensive chart is prepared for fore- 

 casting in that Province. The daily weather chart shewing the Meteor- 

 ological conditions over the Northern Hemisphere was discontinued 

 on the outbreak of the War, and its loss is to be greatly deplored, 

 as it was undoubtedly a very great assistance in forecasting the paths 

 of storms. 



Storm warnings have been issued to 1 12 display stations in Canada 

 and of 2037 warnings issued 88% were verified by subsequent high 

 winds; 323 warnings were received late; 204 owing to issue and 119 

 owing to telegraphic delays. Forecasts have been telegraphed twice 

 daily to Newfoundland and warnings of expected storms were issued 

 on 34 occasions. 



Forecasts have been telephoned twice daily to the Radio-tele- 

 graph station on Toronto Island whence they are transmitted to the 

 various wireless stations on the Great Lakes. Forecasts and storm 

 warnings have also been telegraphed to the Radio-telegraph stations 

 at Montreal, Fame Point and Halifax and to the Superintendent of 

 the Signal Service, Quebec, and from these points have been dissemina- 

 ted broadcast to all vessels equipped with wireless apparatus. Ar- 

 rangements have also been made within the year whereby copies 

 of the daily bulletins supplied to most of the larger towns and villages 

 in Ontario are handed to the Central telephone exchange office, the 

 Bell Telephone having agreed to furnish the same to any of their 

 subscribers who may ask for them.
