Perfect late summer weekend

They don't not come any better than this upcoming weekend's forecast for Montreal and eastern Ontario. Strong high pressure will be in control of the weather with warm sunshine pushing temperatures very close to 30C. This is easily 5 to 7 degrees above normal for late August. Overnight lows will be pleasant dropping back into the teens. So it is A/C during the day and windows open at night. There really is not much else to tell, enjoy the weather.

Deep convection is beginning to spread out in large tropical storm Isaac. Winds are only 45mph but strengthening is forecast. Isaac will produce heavy rains and flooding today across Puerto Rico and the Dominican Republic into Haiti.

Tropical Storm Isaac
Things will begin to break down by Monday in Montreal with the approach of a strong cold front introducing some showers and thunderstorms to the area along with slightly cooler weather. Our focus will then turn to developing Tropical Storm Isaac and the impacts expected locally. Isaac this morning is strengthening a little as he sits 165 miles south of Santo Domingo. Forecasters expect Isaac to increase in strength today with a slight risk of reaching hurricane status before interacting with Cuba and Haiti. Beyond 48 hours into this weekend we are looking at Isaac re-emerging over the open waters of the Straits of Florida near Key West and moving into the eastern Gulf of Mexico. Depending on how much time Isaac has to develop we may be dealing with a major hurricane approaching the the Mississippi/Alabama Gulf Coast by Tuesday. Once inland the storm will move into the Ohio Valley and could bring rain and wind by the middle of next week to Quebec. We need to watch this storm carefully and I will update the blog all weekend as well as the twitter feeds on the left. There is the potential for this storm to cause serious flooding and mudslides today across Haiti and the Dominican. Rainfall totals could exceed 10 inches. A state of emergency may be declared later today for the Florida Keys. Interests all along the Gulf Coast from New Orleans to the big bend of Florida need to begin to listen to the forecast very carefully and review there hurricane plans.
