A severe thunderstorm warning has ended for the Ottawa region after residents saw heavy rain, hail, high winds and lightning move through the region.

The storm cell hit the Renfrew area before moving through Ottawa and continuing east. Environment Canada ended the storm warning at 6:11 p.m.

The storm followed a hot and humid morning and day in Ottawa, a weather pattern that could repeat itself on Tuesday.

On Tuesday, the temperature is expected to reach 32 C again and there is a 40-per-cent chance of showers in the afternoon and evening with the risk of a thunderstorm.

Hot, humid day in Ottawa

Environment Canada had issued a humidex advisory Monday morning as the temperature was expected to reach a high of 32 C.

Ottawa paramedics said they responded to two calls for heat exhaustion that required hospitalization. Both patients are in stable condition after getting into cooler environments and rehydrating, according to paramedics.

Ottawa Public Health has issued heat advisories for both Monday and Tuesday.

Heat-related illnesses include dehydration, heat exhaustion and heat stroke. Seniors, infants and the homeless are at greater risk, as are people taking anti-depressants or medications for Parkinson's disease.

Public health urges people to drink plenty of fluids, and to seek shade and shelter at the first signs of heat exposure. People are also advised to spend at least two hours per day in an air-conditioned space.
