EMSA has issued a Medical Heat Alert on Sunday after responding to five suspected heat-related calls in the Tulsa area.
A heat alert is issued when EMSA responds to five or more suspected heat-related calls in a 24-hour period.
High temperatures in the Tulsa area are forecast to be in the mid- to upper-90s on Monday and Tuesday, and low- to mid-90s on Wednesday, and near 90 on Thursday, according to the National Weather Service.
"With very hot temperatures forecast for the coming week, EMSA is urging citizens to make a plan to stay safe over the next several days," the agency said in a news release.
"Plan the amount of time you think will be outdoors and take appropriate amounts of water or other fluids with you, even if just planning for a short amount of outdoor time. Emergencies can happen and you could be stranded outdoors longer than expected. Always have a cell phone with you to call 911, if needed."
