Another hot spell and growing humidity will be making its way to the Forest City and surrounding areas.
Environment Canada has issued a heat warning for London, Parkhill, Strathroy, Komoka as well as Eastern and Western Middlesex County.
The national weather agency says that a hot and humid airmass will return from the United States beginning Tuesday afternoon, when afternoon temperatures are forecast to reach the low 30s.
“On the back end of it, you get a southwest flow behind it,” said AM980 Weather Specialist John Wilson. “That picks up that heat and humidity that is down in the Mississippi Valley and brings it north.”
With temperatures expected to climb to 31ºC by mid-afternoon Tuesday, the Middlesex-London Health Unit has issued the sixth extreme temperature alert of the summer, this time as an “Extended Heat Warning”.
The warning will remain in effect for four consecutive days.
The MLHU recommends that people limit the time they spend outdoors during the warning.
Londoners are asked to:
- Avoid strenuous outdoor activity.
- Seek shade or air conditioned spaces.
- Drink water to stay hydrated.
The Health Unit is warning that overexposure to heat and humidity can lead to symptoms of heatstroke, which include:
- Muscle or abdominal cramps

Depending on the conditions, the MLHU could remove the warning around Friday.
