MONTHLY ICE CONDITIONS— 1966 



JANUARY 



The Grand Banks area remained clear of ice throughout January 

 (refer to a prior section of this bulletin for an explanation). A flight 

 to Cape Chidley, Labrador, on the 20th observed a minimum numlier 

 of bergs and only a narrow band of pack ice extending nortliward 

 along the Labrador coast. Figure 2 shows the distribution of bergs and 

 delineates the pack ice south of Cape Chidley. On the 29th, an intense 

 low accompajiied by hurricane force winds (refer to fig. 3), passed 

 south of Newfoundland. This storm, with wind-driven waves in 

 excess of 22 feet destroyed all bergs south of 54°50' N. latitude and 

 destroyed a gi'eat deal of the pack ice as far north as 58° N. latitude. 



The Strait of Belle Isle remained open for shipping throughout the 

 month. Sea. ice began to form in the western part of the Gulf of St. 

 Lawrence. The eastern Gulf of St. Lawrence and Cabot Straits re- 

 mained free of ice except for a narrow strip of open pack along the 

 Labrador coast. 



FEBRUARY 



The Grand Banks remained free of ice throughout Februaiy. By 

 the 10th, pa^k ice, with only a few growlers, extended south to only 

 49°20' N., 51°50' W. By the 24th, pack ice, with only a few growlers, 

 extended south to 47°50' X, 52°00' W. Tlie intense low of the l^th, 

 located at 53° N., 53° W. at 0600 G.m.t. of that date, generated large 

 waves, materially aiding pack ice and berg deterioration as far north 

 as Cape Chidley, Labrador. The southernmost l>erg was located at 

 49°25' N., 52°50' W. on the 25th. Only 18 bergs were observed from 

 Notre Dame Bay to Belle Isle area. 



The predominant winds for the month were onshore and relati\"ely 

 warm. The bergs and pack ice were contained close inshore along New- 

 foundland and Labrador. Refer to figures 4, 5, and (> for the distribu- 

 tion of ice to Cape Cliidley, Labrador, aaid the abnormal weather con- 

 ditions, respectively.
