arose as to whether Debby would interact with an approaching trough or enter the influence of a ridge over the southeastern United States. The storm was later picked up by the trough, moving away from land and moved to the north. Debby strengthened further, becoming a minimal hurricane late on September 14. The hurricane deepened further, reaching maximum winds of , a Category 2 storm. Debby approached Bermuda in this time, and on September 16, Debby passed west of the island and continued north. Debby began to slow down to early on September 17 as another trough in the westerlies arrived and the system entered it. As the hurricane entered the trough, its forward speed picked up from . During this time, Debby reached Category 4 strength, reaching a peak intensity of and a minimal pressure of . Early on September 19, Debby passed just south of Cape Race, Newfoundland and started accelerating to the east at on the following day. Debby remained a tropical cyclone while crossing the North Atlantic Ocean and weakened to a tropical storm at 0600 UTC September 20. Debby was rapidly approaching the British Isles on September 20 shortly before it transitioned into an extratropical cyclone. The remains of Debby maintained plenty of intensity over northern Europe, and on September 21 it struck northern parts of Finland (where it was named storm Mauri) as one of the most powerful windstorms in the country's recorded history. Winds over felled millions of cubic metres of forest, and a storm surge severely damaged the cities of Kemi and Tornio, claiming two lives. Starting in the 1982 season (with Debby), the Hurricane Hunter Aircraft (also known as P-3s) began running a new mission for NOAA's Hurricane Research Division. The mission was to drop dropwindsondes that deployed very-low Omega frequency signals. These signals were to estimate the sonde's motion compared to the aircraft in certain areas in a storm. Preparations and impact Rainfalls from Debby in Puerto Rico ranged between around the northern end of the island to in the southern ridge of the island. Rains on the island peaked at in Penuelas. The U.S. Virgin Islands reported rain of about , while about of precipitation fell in Dominican Republic. The United States Navy removed its 700 personnel on Bermuda's Air Force Base, placing them in a gymnasium nearby. Thousands of tourists took last-minute flights out of Bermuda on September
