Most of New Brunswick is being covered by a special weather advisory for Canada Day as Environment Canada expects the humidex to reach close to 40.
“A warm and humid air mass over New Brunswick today and Canada Day will cause humidex values to reach between 35 and 40 over most of the province with the exception of some coastal areas,” according to Environment Canada.
“There is a chance that some inland areas of New Brunswick may see humidex values exceeding 40 on Canada Day.”
The heat and humidity prompted Fredericton to issue a Level 1 heat alert.
The city says temperatures in this range “can affect the young and elderly, especially those with pre-existing respiratory and cardiovascular diseases."
The entire province is covered by a ban on burning, according to the provincial government.
As temperatures began to increase over the weekend, the SPCA in the Maritimes reminded pet owners not to leave their animals in vehicles.
