Ainda bem que nao trabalho no principio da proxima semana... Leslie vai deixar muito trabalho para nos, Canadianos. Varios modelos fazem fassar o centro da tempestade ao este da Nova Escocia (Nova Scotia) e directamente sobre Terra Nova (New Foundland).

Mas eu estive a ver o GEM GLOBAL, o modelo canadiano, e fazem-no passar mais no interior. Isto quer dicer que o Quebeque e New Brunswick serao tambem afectados por chuva e vento.

Nao creio que o modelo canadiano tenha razao porque ainda no principio de esta semana o GLOBAL tem a tendencia de fazer explodir depressoes e empurrar-las mais para o interior do continento.

EDIT: Aqui estao imagens do modelo canadiano. De Segunda 00z até Terça 00z

A Tropical Strom Warning has been issued by the Bermuda Weather Service for that island. Tropical Storm Leslie is centered this Saturday morning about 325 miles south-southeast of Bermuda, moving toward the north at 5 mph. This general direction, with a gradual increase in forward speed, is expected through Sunday, before turning north-northeast Sunday Night. The center of Leslie is expected to pass east of Bermuda on Sunday wth tropical storm conditions arriving there by early Sunday. Maximum sustained winds are 65 mph, but Leslie could regain hurricane strength over the weekend.
Elsewhere, Hurricane Michael is still a Category Two hurricane on the Saffir-Simpson Hurricane Wind Scale, with maximum sustained winds of 100 mph. It's centered over the open waters of the Atlantic about 925 miles west-southwest of the Azores. A slow northwest motion and a gradual weakening is expected through the weekend. Michael is not a threat to land.

Tropical storm-force wind gusts are occurring over Bermuda on this Sunday morning. Tropical Storm Leslie is centered about 170 miles southeast of Bermuda, moving north at 9 mph. Leslie should pick up some forward speed today, then turn more toward the north-northeast tonight or Monday. On that track, the center will pass east of Bermuda later today. Tropical storm conditions will continue over Bermuda today, with 2 to 4 inches of rain expected as well. A Tropical Storm Warning continues for the island. Maximum sustained winds are 65 mph, and Leslie could still regain hurricane strength during the next day or so.
Meanwhile, Hurricane Michael has changed little in strength, still a Category Two hurricane on the Saffi-Simpson Hurricane Wind Scale with 100 mph winds. It's centered over the open waters of the Atlantic Ocean about 925 miles west-southwest of the Azores. Gradual weakening is expected as it turns west today, then back toward the northwest on Monday. Michael is not a threat to land.

Tropical Storm Leslie is heading for Newfoundland. Environment Canada has issued a Hurricane Watch for southeastern Newfoundland from Stones Cove to Charlottetown, and a Tropical Storm Watch from Indian Harbour to Stones Cove and from Fogo Islands to Charlottetown.
The center of Leslie is located about 870 miles south-southwest of Cape Race, Newfoundland, moving toward the north-northeast. The forecast track brings the center of the storm over southeastern Newfoundland on Tuesday morning.
Maximum sustained winds are 60 mph. Some strengthening is possible, and Leslie could be near hurricane strength as it approaches Newfoundland. It's also expected to begin a transformation to an extratropical or frontal cyclone as it approaches the Canadian Maritimes.
Meanwhile, Hurricane Michael has weakened a little more this morning. Maximum sustained winds are 80 mph, a Category One hurricane on the Saffir-Simpson Hurricane Wind Scale. More weakening is forecast, and Michael could become a tropical storm by tonight. It's centered more than a 1000 miles west of the Azores, moving toward the west. A turn toward the northwest is expected by tonight. It is not a threat to land.
