A person has died from heat-related complications, Dallas County health officials say Thursday.

To protect the person's identity, no other information was released.
The latest news from around North Texas.
There were two heat-related deaths in Dallas County in 2015, the health department said.
A heat advisory is in effect for all of North Texas, including the Dallas-Fort Worth Metroplex, through Saturday evening.
High temperatures are expected to reach the middle and upper 90s each day, with the heat index approaching values around 105 degrees due to a high amount of humidity in the air.
Heat exhaustion or heat stroke can quickly develop when the heat index is that high, the National Weather Service warns. Avoid serious illness by drinking plenty of water, wearing light and loose-fitting clothing when possible and avoiding strenuous outdoor activities during the afternoon.
With such oppressive heat in the forecast, North Texans are reminded to check on their friends and loved ones with health problems as they may be among the most susceptible to heat exhaustion and heat stroke.
As always, never leave young children or pets unattended in an enclosed vehicle, even for a short amount of time, as temperatures can quickly rise to threatening levels.
Pets should not be left unattended outdoors for more than a few minutes.
Water is the cornerstone to staying safe this week, according to the Centers for Disease Control and Prevention. Officials said it's important to start drinking before becoming thirsty and if you know you're going to be out in the heat, begin drinking water the night before.
Officials recommend staying indoors, but anyone who must be outside should drink a cup of water about every 20 minutes and wear lightweight, loose-fitting clothing.
