The National Weather Service has indicated that excessive heat is expected for most of Northern California in the next few days.

The National Weather Service in Sacramento has issued an Excessive Heat Warning, which is in effect from 11 a.m. Wednesday to 10 p.m. Friday.
Impacts for local residents could include heat related illnesses such as heat exhaustion and heat stroke, which can occur due to prolonged exposure to hot temperatures. People most vulnerable include those who are spending lots of time outdoors, those who do not have air conditioning, young children, the elderly, and those with chronic ailments.
Affected areas for this excessive heat warning are: Clear Lake/Southern Lake County, the Central Sacramento Valley, the Southern Sacramento Valley, the Northern Sacramento Valley, the Northern San Joaquin Valley, the Carquinez Strait and the Delta.
An Excessive Heat Warning means that a prolonged period of hot temperatures will occur and create a dangerous situation in which heat illnesses are likely. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. 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 light weight and loose fitting clothing when possible and drink plenty of water. 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. Heat stroke is an emergency, call 9-1-1. Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.
