Tropical System Frequency for Each Region of Newfoundland and Labrador, by Month (1954-2011) The frequency of tropical storm occurrence in Newfoundland and Labrador, and the entire North Atlantic, can vary considerably from year to year and decade to decade. Tropical storm activity in Newfoundland and Labrador peaked in the 1960‟s and 1970‟s before reaching its lowest levels in the 1980‟s. But, activity in the past 20 years has increased considerably, especially over Eastern Newfoundland and the surrounding marine areas. 1997 was the last year where no tropical storms affected Newfoundland and Labrador. Since that time, an average of 2 – 3 storms have tracked across or near the province, including the peak year of 2006 when 5 storms affected the region. The total number of tropical systems which have affected each region of Newfoundland and Labrador, by decade, is plotted in Figure 3-17. TA1112733 page 64
