Tropical Storm Dean originated off the Lesser Antilles on August 22, 2001. Only developing into a tropical storm, Dean sustained winds as high as 111 km/h (60 knots) within the CHC Response Zone. Moving northeastward, Dean crossed the Grand Banks marine areas near Newfoundland and passed about 250 km southeast of Cape Race during the morning hours of August 28. Thereafter, Dean weakened as it moved out over the north Atlantic. Hurricane Dean left the CHC Response Zone, diminished on August 29, and did not result in any damage to Canada. This was the first of 4 tropical cyclones within a span of a month that brought over 100 mm of rain to portions of Newfoundland as it passed southeast of the province. The CHC issued 6 Hurricane Information Statements.
