Furacão IGOR (Atlântico 2010 #AL11)

O Igor agora como potente ciclone extra-tropical parece que está a ter um enorme impacto na Terra Nova, muitas localidades isoladas, pontes destruídas, estado de emergência decretado em muitos municípios

According to the RCMP, rain has completely washed out the Rattling Brook Bridge on Route 210, cutting off the peninsula's only link to the Trans Canada Highway. In fact, roads all over the peninsula have been washed out or submerged, including the town of Clarenville. Robert Hiscock, Chief Administrative Officer in Clarenville, NL spoke to The Weather Network earlier today. He says that not only is the town isolated because the Trans-Canada is closed on both sides, but other infrastructure is being affected. “...some abutments are being undermined on various bridges and concrete structures, and we expect we'll lose them.”

Between 150 and 200+ mm of rain is expected to completely wash out parts of Newfoundland as Igor continues to swing towards the province's east coast leaving at least seven communities under a state of emergency. “We have declared a state of emergency. We have evacuated a number of areas in town, where we felt there was property damage or there was a threat to life safety. We've evacuated these people to the town's arena and some of the school's gymnasiums,” explains Hiscock.

The Town council in Marystown has declared a state of emergency because of the all the washouts for the town to handle as well as the town of Glovertown and according to Mayor Peter Lush, residents in Gambo south have been evacuated.

Meanwhile, the Town of Sunnyside is also under a state of emergency after heavy rains flushed out their main road at Badger Brook. According to officials, the town no longer has water and sewer. A huge crater in the middle of the road has practically cut the town in two. Residents living in the upper part of the community can get out, whereas those in the lower part are cut off.

“The situation is extremely bad, emergency crew have been out since 4 a.m. this morning. We have reports of structures being demolished...some people are in threat of losing their own homes.”

Disaster volunteers and staff with the Canadian Red Cross are assisting authorities in Clarenville. Two comfort centres for residents have been set up for those that have left their homes due to flooding associated with Igor. The centres are located in the Clarenville Middle School and the Event Centre, and will remain open until local officials decide otherwise.

Many towns are also experiencing power outages, from electrical lines that have been downed by the ferocious hurricane-force winds. Other regions across Newfoundland are also being affected by the shearing winds.

Roads are shut down from Charleston, Southern Bay, Summerville, Princetown and the highway between Southern Bay and Trinity. Police are asking everyone to stay off the roads and remain inside.

O rasto de água arrefecida pelo IGOR nos mapas de anomalia da temperatura da água. Um bom exemplo da energia envolvida num ciclone potente e das trocas de calor Oceano-Atmosfera

Igor's Wake Seen in Ocean Temperature Data
Hurricane Igor, the 4th Atlantic hurricane of the 2010 season, took the characteristic path of Cape Verde storms, heading on a course towards Bermuda and then north through the Western Atlantic. Reaching Category 4 intensity with maximum sustained winds of 155 mph, Igor also became the second largest storm in overall area ever observed in the Atlantic. This combination of size and strength left a wake of cool water behind the storm, which is visible in the sea surface temperature anomaly data from September 20, 2010. This dataset compares the sea surface temperatures observed on that particular day to the historical average of that day from 1971-2000. Areas that are cooler than normal are colored blue, areas warmer than normal are red. As hurricanes move across the ocean basins, heat energy is extracted from the water to fuel the storm, resulting in cooler temperatures after the storm passes through the area. In addition, the strong winds and waves associated with tropical cyclones mix up the water column, bringing cool, deep water to the surface. Also visible in this image are the relatively hot waters of the Southern Caribbean, in part due to the relative lack of cyclonic activity in this region so far.

Alguns efeitos do furacão Igor.

Parece incrível, mas até nós em Portugal vamos ser afectados por este furacão Igor, o que dá uma ideia do poder e da força da natureza!

Ok, soam mal estas minhas palavras, mas não deixam de ter um fundo de verdade. A partir desta noite e até Domingo chegará até à Costa Ocidental a ondulação proveniente deste furacão (3/3,5 m). Não é nada de extraordinário, mas se o vento não aparecer as ondas nas praias mais expostas terão alturas bem consideráveis, suficientes para proibir qualquer banhista de se aventurar na água! Nota para o período das ondas muito elevado (16/17 segundos)...
