Dangerously hot conditions are forecast in the region, expected to impact local communities beginning on Friday.

The National Weather Service in Sacramento has issued an excessive heat warning, in effect from noon Friday, July 9 to 9 p.m. Monday, July 12.

Affected areas will include the Sacramento Valley, northern San Joaquin Valley, adjacent foothills, and mountains up to approximately 6,000 feet elevation.

Valley and foothill afternoon highs could be as high as 100 to 115 degrees, with overnight lows in the upper 60s to low 80s. Mountain highs will be in the 80s up to 105 degrees, with lows in the 60s to middle 70s.

Extreme heat will significantly increase the potential for heat-related illnesses. Hottest temperatures are forecast to occur on Saturday and Sunday, July 10 and 11. The potential for minor relief from the heat will arrive to the Delta and possibly Sacramento Metro Area as early as Monday.

Forecasters urge residents to take precautionary/preparedness actions. 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. Anyone overcome by heat should be moved to a cool and shaded location.
