After a devastating forest fire season in 2017, tougher penalties in an effort to reduce wildfire risk, have been made law this year – ahead of the dry season. Read more about new failure to comply measures put into law.

It is common for summer temperatures to peak between 30-35 degrees Celsius during the summer months in the Southern Interior. Coupled with long stretches of dry, sunny weather, and low relative humidity.

Hot and dry weather will be the story through the beginning of this week with the Southern Interior reaching the low 30s. In Kamloops, an air quality statement, together with a heat warning have been issued. A respite from the heat is expected mid-week with the arrival of upper-level trough. 

As early as Thursday & Friday, cooler temperatures will spread across the Interior. A chance of rain and cloudier conditions will be welcomed in some communities – but others who see lightning could see new fires.

On Vancouver Island, sunny and pleasant conditions are expected to persistent for many days. Coupled with low-humidity, the Victoria vicinity will see rising fire ratings. 

Unfortunately, high-pressure will return to British Columbia next week. Temperatures will once again soar into the high 20s or 30s. The dry season may persist well into August this year.

Isolated Severe Storms Slice Humidity in Ontario & Quebec

Scattered thunderstorms are expected across the lower half of Southern Ontario and Southwestern Quebec today (July 2nd, 2018).

A weak cold front will slowly track across Southern ON/SQUE today acting as a trigger for thunderstorms. The frontal passage is not expected to offer much relief from the heat, but will lower humidity to more comfortable levels tonight and Tuesday.

The primary risk with these thunderstorms will be torrential rainfall. Due to slow movement of the frontal passage some thunderstorms may “train” or, regenerate over the same region bringing locally 30-50mm in a short period of time. Additionally, isolated damaging winds are possible – primarily in Eastern Ontario and Southwest Quebec where the greatest risk for severe exists. Small hail between pea and dime size is possible in the more robust updrafts across the entire isolated severe risk zone.

The timing for storm development today, will be between 11am-6pm. We have highlighted localized municipalities – stretching from the Golden Horseshoe into Eastern Ontario in a isolated severe threat.
