New Brunswick
Environment Canada says a period of very warm and humid weather is expected for most of central and southern New Brunswick.
Temperatures will reach near 30 degrees Celsius Wednesday, though the humidex will make it feel more like 37 degrees. It will then cool down to around 20 degrees Wednesday night.
Similar hot and humid conditions are also expected on Thursday before turning cooler Thursday night.
Nova Scotia
Heat warnings are also in place for much of northern Nova Scotia, including Cape Breton and the Annapolis Valley.
Temperatures are expected to reach up to 31 degrees Celsius Wednesday, with humidex values between 35 and 37.
It will then cool off to around 20 degrees Wednesday night before reaching back up to 29 degrees on Thursday. Temperatures will then turn cooler by Thursday evening.
A severe thunderstorm warning is also in place along the south shore of Nova Scotia Wednesday morning. Environment Canada says conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain.
Prince Edward Island
Meanwhile, all of Prince Edward Island is under a heat warning.
Environment Canada says the maximum temperature will reach up to 30 degrees Celsius Wednesday and the humidex will be 37. Temperatures will then go down to about 20 degrees Wednesday night.
Thursday will be another hot and humid day on the island, with maximum temperatures around 30 degrees and a humidex of 37.
Tips to stay cool
Environment Canada recommends checking on older adults, people living alone and others at-risk either in-person or on the phone during extreme heat.
Signs of heat exhaustion may include:
headache
nausea
dizziness
thirst
dark urine
intense fatigue
If you suspect you may have heat exhaustion, it's recommended you stop what you're doing and drink water.
If you suspect you or someone around you is having heat stroke, call 911.
Signs of heat stroke can include:
red and hot skin
dizziness
nausea
confusion
change in consciousness
While you wait for medical attention, it's recommended you try to cool the person down by moving them to a cool place, removing any extra clothing, and applying either cold water or ice packs around their body.
'Drink water often and before you feel thirsty to replace fluids. Close blinds, or shades and open windows if outside is cooler than inside. Turn on air conditioning, use a fan, or move to a cooler area of your living space,' reads Wednesday's warning from Environment Canada.
'If your living space is hot, move to a cool public space such as a cooling centre, community centre, library or shaded park. Follow the advice of your region's public health authority.'

A heat warning was issued for most of east-central and southeastern Alberta on Wednesday, including Calgary, Red Deer and Edmonton. Those warnings have been lifted for the QEII corridor Thursday due to cooler temperatures expected, but continued for southeastern Alberta with daytime highs expected to reach the low 30s.

Flossie weakens to tropical storm off Mexico's Pacific coast
Tropical Storm Flossie is seen off the Mexican Pacific Coast on Thursday, July 3, 2025. (NOAA) MEXICO CITY — Hurricane Flossie weakened to a tropical storm Thursday off Mexico's southwestern Pacific coast with maximum sustained winds of 60 mph (95 km/h), the U.S. National Hurricane Center said. It's expected to remain offshore and dissipate Thursday, but swells, 'life-threatening' surf and rip currents were expected in southwestern Mexico and the Baja California peninsula in the coming days. The Miami-based centre said Flossie was about 205 miles (330 kilometres) south-southwest of Cabo San Lucas and was moving northwest off the Mexican coast at 9 mph (15 km/h). It was expected to skirt the coast for a few days while dropping rain on several Mexican states. Flossie became a powerful Category 3 hurricane late on Tuesday, but gradually weakened throughout Wednesday. ___ The Associated Press
