Earl to Threaten Nova Scotia, Newfoundland

Soon after mighty Hurricane Earl curves northward, paralleling the East Coast of the U.S. late this week, the storm will threaten Nova Scotia and Newfoundland with a possible direct hit to start the weekend.
While Earl does not appear to be another Hurricane Juan of 2003, it will hit with increasing forward speed and dangerous conditions.
Winds of 75 to 100 mph (120 to 160 kph) may batter the southeast coast of Nova Scotia Saturday morning, then southern Newfoundland Saturday night.
AccuWeather.com meteorologists expect Earl to affect these areas as a Category 1 or 2 hurricane.
Seas of 20 feet or higher may batter the south coast of both Canadian provinces.
Halifax, Nova Scotia, lies in the middle of the projected path of Hurricane Earl at this time. However, many other coastal towns lie in harm's way.
Hurricane Juan hit as a Category 2 storm during late September at nearly a 90-degree angle to Nova Scotia with little time to dissipate before making landfall and was just about a worst case scenario. Six people lost their lives in Nova Scotia as a result of Juan.
Earl will be arriving from the southwest, perhaps paralleling the coast or moving just inland. While this path will favor rapid weakening, it also favors more square miles of adverse effects.
The strongest winds and biggest waves and storm surge generated by a hurricane are typically on its northeastern flank.
Be aware, conditions will deteriorate rapidly along this stretch of Canadian waters.
The fast movement of Earl, perhaps accelerating to 30 mph (50 kph) in northern latitudes, will limit its duration but may also catch unsuspecting coastal residents, visitors and mariners by surprise.
People should be prepared for falling trees and downed power lines, as well as damage to roofs and other structures, such as boats. Unsecured objects will become airborne projectiles. Waves will over wash some roadways.
Earl will be changing character over Atlantic Canada to a non-tropical feature and will unload windswept, heavy rain over a broadening area. While fast movement will limit inland flooding, it is still a possibility. Landslides could block some roads. Erosion from runoff may damage other highways.
