UPDATE: Leslie has weakened into a tropical rainstorm at 11:00 a.m. ET Tuesday, Sep. 11, 2012 as it pulls away from Newfoundland.

After a 12-day run through the Atlantic and a dance with Bermuda, Leslie buffeted Newfoundland with storm surge, flooding rain, pounding surf and high winds through early Tuesday.

Leslie began accelerating northward on Monday and took aim on eastern Newfoundland. On Monday night, Leslie increased her movement to over 40 mph (64 kph) on a direct course just west of St. John's.

Most of the hurricane-force wind gusts were confined to coastal areas along the Avalon Peninsula.

A wind gust of 82 mph (132 kph) was measured in St. John's, Newfoundland, shortly after 7 a.m. ET Tuesday, Sept. 11, 2012, while Leslie prepared to move onshore in Newfoundland.

Leslie produced heavy rainfall even well ahead of the center of her circulation. The interaction with a cold front to the west not only delivered windswept rain in parts of Newfoundland, but also torrential downpours to Nova Scotia.

Twillingate and Rocky Harbour, Newfoundland received 1.84 inches (47 millimeters) and 1.51 inches (38 millimeters) of rain respectively. Tracadie, Nova Scotia picked up 4.56 inches (116 millimeters) with 4.42 inches (112 millimeters) of rain falling on Caribou Point, Nova Scotia.

A storm surge may have caused significant over wash on St. Mary's Bay and Placentia Bay.

Coastal inundation of 3-6 feet (1-2 meters) will continue before subsiding later in the day on Tuesday.

As Leslie continues to blast northward, she will undergo a transition from a tropical system to a powerful area of low pressure, pulling away from Newfoundland.

By late in the day on Tuesday, Leslie will be well north of Newfoundland, and only a few showers and a gusty northwest breeze at 15-25 mph (24-40 kph) will remain.
