Atlantic Canada could feel an impact from Tropical Storm Chris which has formed off the coast of the Southeastern U.S.
The Canadian Hurricane Centre says the third named storm of 2018 will move northeastward and possibly strengthen to become a hurricane by early Wednesday.
The storm could weaken as it approaches Nova Scotia by Thursday.
The CHC notes there is still uncertainty in the forecast track and intensity of this system.
Beryl is the second named storm but first hurricane of the season and has been down downgraded to a tropical storm as it heads toward Puerto Rico.
Meantime, Environment Canada issued another heat warning for New Brunswick except the Fundy coast, Prince Edward Island and northern Nova Scotia as a warm, humid air mass pushes highs into the low 30s C with humidex values up to 38 on Monday.

The passing of a cold front led to showers and thundershowers in Southeast New Brunswick today marking the end of hot, humid weather.
Environment Canada has noted Greater Moncton endured an official heat wave by definition with three straight days of at least 32°C.
The trio of record highs this week:
JULY 3rd : 31.6 C (new), 31.0 C (old record 1984)
JULY 4th : 33.4 C (new), 31.6 C (old record 2013)

As the heat subsides in Eastern Canada, hot weather is building in Western Canada with an impressive record high today of 39.3 C at Val Marie, Saskatchewan.

Record highs could be broken in Greater Moncton over the next couple of days if forecast highs in the low to mid 30s C are reached on Tuesday and Wednesday.
Environment Canada has issued a rare heat warning for New Brunswick, mainland Nova Scotia and Prince Edward Island with cooler conditions along the coast.
A warm, humid airmass is expected to push humidex values about 40 during the day and barely falling below 18 C at night – dangerous levels for those susceptible to heat.
Forecasters believe warm, humid weather will persist until later this week when a cold front brings temperatures closer to normal for the weekend.
Ogilvie Brook, Irishtown Nature Park, 24 June 2018 (Dearing)
Greater Moncton has endured the coolest June in recent memory and while daytime highs were close to normal – with a few exceptions – overnight lows were cold, even frosty at times during the first half of the month.
A hard frost on 04 June with a record breaking low of -3.2 C was devastating for agriculture across New Brunswick especially in the Southeast.
Farmers suffered major damage – in some cases 50 to 80 percent losses – to crops such as grapes, strawberries and blueberries.
Oddly enough, the temperature had not been that low in all of May and not since 16 April had it been at least that cold.
Rainfall was about 60 percent above normal and was confined to a handful of major rain events with nine days being completely dry.

At long last, warm weather is finally pushing into New Brunswick after the coldest June in recent memory.
Environment Canada says a warm, humid air mass will settle over the Maritimes this weekend and persist into next week.
Temperatures in the low 30s Celsius are expected with high humidity making it feel much warmer.
Relief will come along coastal areas which can expect slightly cooler conditions.
The summer solstice officially arrived in New Brunswick at 7:07am ADT today.
This is the longest day of the year with 15 hours and 46 minutes of daylight in Moncton.
The sun is directly over the Tropic of Cancer and it will now begin moving south toward the equator which means days will be getting shorter again – by three seconds starting tomorrow.
As for summer weather predictions for the region, the Weather Network is suggesting July and August will have slightly above normal temperatures with high humidity.
Environment Canada believes there is an 80 percent chance of higher than average temperatures and a 40 percent chance of below normal precipitation.

Farmers are already suffering from tremendous losses in the region with crops such as grapes, strawberries, blueberries and apples being hit by a recent hard frost with a low of -4 C in some areas.
