LOS ANGELES, Calif. (KTLA) -- Cooler temperatures are forecast for Southern California Friday, ending an extended heat wave that sent the mercury soaring into the triple digits.
Expect a 10 to 15 degree reduction in highs as the onshore flow strengthens and pressure drops on Friday. Morning low clouds and fog will develop and spread over portions of the coastal plain. By mid-morning skies will be mostly clear across the region. Look for a temperature range from the low 70's at the coast to mid 90's in the valleys.
Winds could become an issue into the weekend with low pressure creating stronger gradients. Wind Advisories may be need for the upper deserts and for the mountains.
The Los Angeles County Health Officer is reminding everyone that precautions should be taken, especially by those people sensitive to the heat.
"While people don't need to be told it's hot outside, they do need to be reminded to take care of themselves, children, the elderly, and pets when the weather gets hotter," said Jonathan E. Fielding, MD, MPH, Director of Public Health and Health Officer. "When temperatures are high, prolonged sun exposure may cause dehydration, heat cramps, heat exhaustion, and heat stroke. Never leave children, elderly people, or pets unattended in vehicles, even with the windows 'cracked or opened,' because temperatures inside can quickly rise to life-threatening levels. It is illegal, according to California law, to leave children alone in a car."
Also check on elderly neighbors and seek shade or air conditioned buildings during the hottest part of the day, the NWS warned.
If you plan to be outdoors, take precautions to protect yourself from the heat.

Individuals with these symptoms should be moved to a cooler, shaded place and given water or sport drinks. More severe symptoms such as diminished judgment, disorientation, pale and clammy skin, a rapid and weak pulse, and/or fast and shallow breathing may indicate heat exhaustion or impending heat stroke and requires immediate medical attention. breathing may indicate heat exhaustion or impending heat stroke and requires immediate medical attention.
