Under the evening sun, a biker uses the paths along the Santa Cruz River Park on April 23, 2020, as temperatures rose above 90-degrees. The temperature in Tucson hit 100 degrees on April 29.

With temperatures reaching up to 107 degrees Thursday, the National Weather Service has issued an excessive heat warning for Tucson. Describing β€œdangerously hot conditions,” the National Weather Service urges Tucsonans to stay indoors as early season high temps will increase the potential for heat-related illnesses.

For those working outside and those planning to spend time outdoors, it’s advised to schedule strenuous activity for early morning or evening, if possible. Wear lightweight, loose-fitting clothing and drink plenty of fluids.

As is the case at all times, young children and pets should not be left unattended in vehicles, the weather service said.

However, it is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes. For more information on the signs of heat-related illnesses, go to tucne.ws/heatsigns. In the event of an emergency, call 911.

The high temp forecast of 104 degrees for Tucson on Thursday would tie the all-time April high temperature, marked in 1989. The excessive heat warning will be in effect locally from 10 a.m. to 7 p.m. Thursday for the Tucson metro area, the Tohono O’odham Nation, Green Valley, Marana and Vail.

It also applies to south central Pinal County, upper Gila River valley, Ajo, Sells, Organ Pipe Cactus National Monument, Picacho Peak State Park, and Safford.
