The Atlantic hurricane season continues to be extremely active. As mentioned, hurricane Jose is still meandering around the Atlantic, and is located this morning 270 miles (440km) east southeast of Cape Hatteras, North Carolina. Jose has 85mph winds, and is moving north at 9mph (15km/h). Jose is already producing elevated surf from southern New England to the Outer Banks. A tropical storm watch is now in effect for coastal regions from Delaware north to Massachusetts. Winds up to 45mph (70km/h) along with up to 4 inches (100mm) of rain are possible for coastal locations Tuesday.
Over the weekend, hurricane Maria developed and is presently located 85 miles (135km) east of Martinique in the Leeward Islands. Sadly, Maria is forecast to become a major hurricane and trek across some of the same regions impacted by Irma two weeks ago. The northern Leeward islands will be impacted as early as Tuesday, with Puerto Rico expected to take a direct hit on Wednesday. All interests in the Bahamas and eastern US will need to monitor Maria carefully over the next week to 10 days.

This spell of perfect weather is coming during the last full week of summer 2017, a season that has for the most part, not been so good. Precipitation was above normal, with temperatures below, not an ideal combination for a city that loves summer. If you like the heat, it was absent most of the season. Montreal officially recorded only one day where the temperatures was 30C (86F) or above. Normally we have at least 9 such days.
Our current stretch of dry, warm weather started last Sunday and is expected to persist right through the upcoming weekend. As the high pressure slides east off the coast, warmer southerly winds will pick up this weekend, with a slight rise in humidity levels as well. Temperatures will be well above normal, averaging 27C (81F) for a daytime high and 13C (55F) for the overnight low. Normally we should be at 20C (68F) and 9C (48F) respectively. The only exception to the sunshine may be a few high thin clouds Thursday, as what is left of hurricane Irma slides across southern New England late tomorrow and Friday. Any showers will remain across southern New York and Vermont. Enjoy the fine forecast, fall officially arrives next Friday, September 22 at 4:02PM.

The storm has left a widespread trail of damage and destruction in its wake, from the Keys to Miami and north to Jacksonville as well as Georgia and South Carolina. Power is out to nearly 6 million residents from Florida to the Carolina's. Sixty five percent of the Florida power grid is down.
Landfall occurred on Sunday morning near Cudjoe Key, with 130mph winds. A peak gust to 141mph was reported at Naples, Florida. On Monday, the storm crept northward across the peninsula while slowly weakening. Even in a weakened state, Irma's broad circulation produced a tremendous storm surge along the east coast of Florida, Georgia and South Carolina. Record flooding is occurring in Jacksonville, along with winds in excess of 75mph. Homes have been damaged and in many cases destroyed. Crews are slowly moving southward across the Florida Keys, inspecting infrastructure and doing a door to door search for victims. To date, 4 fatalities have been blamed on Irma in Florida, 10 in Cuba and 20 across the rest of the Caribbean. Hundreds of thousands of Florida residents remain in shelters today, unable to return home due to damaged, blocked or flooded roads. Relief is pouring into the region, and FEMA is on the ground. Included in the relief effort, will be 175 utility employees from Ontario's Hydro 1.

Irma will remain a very dangerous storm as the system sweeps from south to north across the Florida peninsula today. Fort Myers, Naples, and Tampa are in the cross hairs for direct impacts form the strongest winds. Already major flooding is occurring, even on the east coast of Florida. Storm surges of 10 to 15 feet are forecast on the west coast, with 6 to 8 feet from the upper keys into Miami-Dade. Power is out to an estimated half million customers already in south Florida. Irma is forecast to move into Georgia on Monday.
I have not forgotten about hurricane Jose. Indications are that this storm may also impact the US. I will deal with that once Irma is out of the way. More updates will follow later today on both systems.

Beyond the Caribbean, forecasters are looking at several guidance models that are leaning towards a Florida landfall of some sort by this coming weekend. Florida Sate Governor, Rick Scott, issued a state of emergency, effective on Monday. I imagine that within the next 24 to 36 hours, if Irma remains on her current path, that evacuations will be needed for at least the Florida Keys. It is early to speculate, but indications are Irma may impact not only Florida, but many sections of the southeast and eastern Seaboard.
