EMSA has issued its second heat alert of the season just in time for the first day of summer.
By Thursday night EMSA had reported five heat-related calls.
In the last week, the hot temperatures and high humidity have sickened 23 people in the metro.
One of those was rushed to the hospital in critical condition.
The first heat alert was issued last Friday, lasting for four days.
If you have outdoor activities planned for the weekend, officials ask you to ensure you stay hydrated.
Wear light-colored, light weight clothing.
If possible, finish strenuous activity in the morning before it gets too hot and ensure you take frequent breaks out of the sun.
