Strong thunderstorms possible today in Ontario & Quebec

A weak cold front will move across eastern Ontario and southern Quebec this afternoon triggering some scattered showers and thunderstorms. While there is only a 40% chance of storms, any that do fire up will have the potential to produce heavy rain and gusty winds. Monitor the weather today for any watches or warnings that may be issued by Environment Canada. The weather remains warm and humid this morning after a high yesterday of 28C and humidex values well into the 30's, we only dropped into the high teens overnight. Temperatures will remain above normal today and Friday before a slight cooling trend into the weekend. After the showers today skies will clear overnight and set the stage for a sunny Friday. The weekend at this time looks wet as we begin the transition into a more fall like weather pattern.
A very impressive and powerful Hurricane Michael in the open waters of the Atlantic this morning with 115mph winds. This storm is no threat to land at this time.
The tropics are very active this week, starting with the remains of Isaac that brought very heavy rain to Atlantic Canada on Wednesday. Amounts were impressive with 50 to as much as 115mm of rain. We have two hurricanes in the open waters of the Atlantic Ocean. Hurricane Leslie has 75mph winds and is strengthening and forecast to move near Bermuda before possibly affecting Newfoundland by early next week. The storm is moving very slowly northward this morning at 1 mph, located about 440 miles from Bermuda. Leslie is producing pounding surf and riptides along the east coast of the US from the Carolinas northward into New England. Further to the east is powerful hurricane Michael located about 1020 miles southwest of the Azores. This storm is also crawling along in the open waters with no threat to land at this time. Michael is a strong category 3 storm with 115mph winds. Finally in an area that does not need more rain and wind, we have a low pressure area in the northern Gulf of Mexico off the coast of Louisiana. This system has a 50% chance of tropical development in the next 48 hours. Forecasters expect it to drift southeast into the Gulf of Mexico.
