Another blast of heat and humidity is set to scorch the London area this week.
Environment Canada has issued a heat warning for London, Parkhill, Strathroy, Komoka as well as Eastern and Western Middlesex County.
The national weather service says that a hot and humid airmass will return from south of the border Tuesday afternoon, when afternoon temperatures are forecast to reach 32 degrees.
With the humidex, temperatures will feel more like 36 degrees, prompting the Middlesex-London Health Unit to issue its sixth extreme temperature alert of the summer, this time as an “Extended Heat Warning.”
The warning will remain in effect for four consecutive days.
Temperatures are expected to climb Wednesday, feeling more like 40 degrees with the humidity. There is a chance of thunderstorms on Thursday, with a high of 33 degrees, the same is expected for Friday.
The MLHU recommends that people limit the time they spend outdoors during the warning.
Londoners are being encouraged to avoid strenuous outdoor activity, seek shade or air conditioned spaces, and drink plenty of water to stay hydrated.
Overexposure to heat and humidity can lead to symptoms of heatstroke, which include headache, confusion, dizziness, fainting, nausea, and muscle or abdominal cramps

Depending on the conditions, the MLHU is expected to remove the heat warning by the weekend.
