The storm drifted until September 9, when it accelerated while passing east of Bermuda. Relatively strong winds on the island caused hundreds of power outages and knocked down tree branches, electrical poles, and other debris. Slight re-intensification took place, with Leslie becoming a hurricane again, before transitioning into an extratropical cyclone near Newfoundland on September 11. In Atlantic Canada, the storm brought heavy rainfall to both Nova Scotia and Newfoundland. In the latter, localized flooding occurred, especially in the western portions of the province. Also in Newfoundland, strong winds from Leslie ripped off roofs, destroyed trees, and left 45,000 homes without power. Additionally, a partially built house was destroyed and several incomplete homes were damaged in Pouch Cove. Overall, Hurricane Leslie caused $10.1 million (2012 USD) in damage and no fatalities.[1]
Meteorological history
A
After becoming a tropical storm on August 30, the subtropical ridge caused Leslie to turn west-northwestward.[2] By the early on August 31, the storm featured well-define outflow in all directions and the center of circulation was close to the main area of convection.[6] Intensity estimates around that time indicated sustained wind speeds of 70 mph (110 km/h).[2] However, intensification halted later on August 31 as wind shear increased over the storm, causing convection to become displaced from the center.[7] Early on September 1, an eye-like feature appeared on satellite imagery; however, there was uncertainty as to whether or not the feature was displaced from the low-level center.[8] The storm became increasingly disorganized, with the circulation displaced from the main convective area several hours later.[9]
Relentless
By early on September 9, the blocking pattern diminished as a broad mid- to upper-level trough and associated cold front moved off the
Preparations and impact
Bermuda
A few tropical cyclone warnings and watches were implemented in relation to Leslie. At 2100 UTC on September 6, a tropical storm watch was issued for Bermuda. The watch was upgraded to a tropical storm warning at 0900 UTC on September 8. By early on September 10, the warning was discontinued.[2] On September 6, officials in Bermuda urged residents to "prepare for the worst". Schools prepared to close Friday as residents got ready for the approaching storm. "Leslie could be a historic storm for Bermuda as it is very large and forecast to intensify rapidly as it approaches," the Bermuda Emergency Measures Organization said. "The island could experience hurricane force winds for a sustained period of time, possibly up to two days."[12]
However, the storm passed further east of Bermuda than initially predicted, causing only minor impact. Nonetheless, sustained winds of 39 mph (63 km/h) and a gust up to 54 mph (87 km/h) was reported in St. David's Island. At the same location, 3.15 inches (80 mm) of precipitation was recorded.[13] Throughout Bermuda, scattered power outages affected hundreds of residents and tree branches and other debris fell on roads; at least one street pole was toppled in Hamilton.[14]
Canada
At 0600 UTC on September 10, a tropical storm watch was issued from
While still a tropical cyclone, Leslie produced 2 to 4 inches (51 to 102 mm) of rain across much of
Elsewhere
While passing to north of the Lesser Antilles, Leslie generated rough surf on various Leeward Islands, the Virgin Islands, and Puerto Rico.[19] Leslie, combined with the remnants of Hurricane Isaac, also produced rip currents along the east coast of Florida, mainly from Nassau County south to Martin County.[20] Additionally, the storm also brought rip currents to coastal Delaware and New Jersey between September 5 and September 6.[21]
