Hurricane Maria led off the month of September, forming as a tropical storm well east of the Leeward Islands on September 2. Maria reached its peak as a Category 3 hurricane on September 5, turning northeast and weakening before becoming extratropical on September 10. Unusually, this extratropical storm strengthened as it moved toward Iceland; its remnants struck Norway where one person was killed in a landslide.
Hurricane Nate formed southwest of Bermuda on September 5 and moved northeast as it strengthened into a strong Category 1 hurricane. Nate became extratropical on September 10; the storm never approached land, although it did interfere with Canadian naval vessels en route to the Gulf Coast to help in Katrina relief efforts.
Hurricane Ophelia formed as a tropical depression in the Bahamas on September 6 and almost immediately made landfall on Grand Bahama. It became a tropical storm off the coast of Florida before strengthening into a large Category 1 storm and raking a long stretch of the southern North Carolina coast with heavy winds and storm surge on September 12 and September 13. The hurricane's eye never made landfall and moved back out to sea before becoming extratropical on September 17 and striking Atlantic Canada. Damages were around $70 million (2005 USD; $78.7 million 2011 USD).[essential hypertensionLouisville Plumber
