Hurricane Larry is expected to make landfall across southeastern Newfoundland late Friday evening. The once category 4 hurricane has been roaming the open waters of the Atlantic for over a week. Larry, now a category 1 hurricane with 130km/h winds, was located 750km southwest of Cape Race, Newfoundland at 2pm Friday afternoon. Larry was racing north, northeast at 60 km/h.

A hurricane warning is in effect for the entire Avalon Peninsula through Saturday morning. Tropical storm warnings are in effect across the Clarenville, Burin and Bonavista regions. Larry is a large hurricane, with hurricane force winds extending outward up to 150km from the center. Forecasters expect the worst of the weather in southeast Newfoundland, including St John's around midnight, lasting through 5AM Saturday morning. Wind speeds are expected in the 110km/h range with gusts up to 140km/h along coastal regions. Winds this strong are capable of knocking down trees and power lines, along with some structural damages. Residents are being urged to prepare for a strong storm through the overnight hours and expect widespread power outages.

Hurricane Larry will rapidly approach the Avalon Peninsula Friday evening while transitioning into a powerful post-tropical cyclone. The center will move towards Greenland on Saturday. (NHC)

Storm surge flooding is possible as well, with large waves accompanying Larry as it races northeast into the north Atlantic. Swells from Larry are already impacting coastal regions from North Carolina to Atlantic Canada. Rainfall from Larry will not be as significant as originally expected due to the rapid movement of the storm, with 30 to 50mm forecast.

Larry is expected to remain a hurricane through landfall tonight and then begin the transition into a strong post-tropical cyclone over the Labrador Sea on Saturday.
