Dangerously high heat will impact the region Friday and Saturday.

The National Weather Service in Sacramento has issued an excessive heat warning for the Delta, the Sacramento Valley and the western side of the Northern San Joaquin Valley and the adjacent foothills

The excessive heat warning is in effect from 11 a.m. Friday, June 10 to 11 p.m. Saturday, June 11.

Dangerously hot conditions are forecast with temperatures from 100 to 106 expected during the day. Overnight lows will be from 65 to 75.

Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.

Friday will have the greatest heat risk threat. Saturday some cooling is expected but high heat risk will continue until a large drop in temperatures arrives in the area on Sunday.

As a precaution, drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.

Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose-fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments.
