Current Los Angeles Area Weather Conditions & Forecast
Exposure to extreme heat can make people seriously ill. Unchecked heat-related illnesses may become a serious problem in a short period of time and can cause death. Though anyone can become a victim to excessive heat, the elderly are among those people most at risk. In recent years, several hundred persons have died in cities across the country as a result of excessive heat during heat waves. Heat cramps, heat exhaustion, and heatstrokes are conditions caused by overexposure to heat. Furthermore, during heavy exercise, a person’s body can generate 10 to 20 times the amount of heat than it does at rest.
Los Angeles has experienced some of the hottest weather in the nation. Los Angeles Police Officers and the citizens of Los Angeles should be aware of risk factors for heat related illnesses in addition to the symptoms of people who might be experiencing a heat related illness.
Los Angeles Police Officers and the citizens of Los Angeles should also be particularly aware of individuals who are at high risk for excessive heat exposure, and make special efforts to insure these individuals are properly cared for. Everyone in Los Angeles is encouraged to check on people they know or come in contact with who are at risk for excessive heat exposure. Everyone should also be prepared to advise at risk individuals of preventive measures for heat exposure and offer assistance when needed. The following information will assist in that endeavor.
Signals include the following: hot, red and dry skin; changes in consciousness; rapid/weak pulse and rapid/shallow breathing. Body temperature can be very high, sometimes as high as 105 degrees Fahrenheit.
IMPORTANT: Since heat index values were devised for shady, light wind conditions, exposure to full sunshine can increase heat index values by up to 15°F. Also, strong winds, particularly with very hot, dry air, can be extremely hazardous.
The Heat Index Chart shaded zone above 105°F (orange or red) shows a level that may cause increasingly severe heat disorders with continued exposure or physical activity.

GENERAL HEAT WAVE EMERGENCY TIPS
GENERAL TIPS TO CARE FOR HEAT-RELATED ILLNESS
Exposure to extreme heat or cold may make a person seriously ill. The likelihood of illness also depends on factors such as physical activity, clothing, wind, humidity, working and living conditions, and a person’s age and state of health. The following tips are important to remember when caring for heat-related illness:
HEAT WAVE TIPS FOR THE HOME
How Fast Can the Sun Heat a Car?
The sun’s shortwave radiation (yellow in figure below) heats objects that it strikes. For example, a dark dashboard or seat can easily reach temperatures in the range of 180 to over 200°F. These objects (e.g., dashboard, steering wheel, child seat) heat the adjacent air by conduction and convection and also give off longwave radiation (red in figure below) which is very efficient at warming the air trapped inside a vehicle.
Shown below are time lapse photos of thermometer readings in a car over a period of less than an hour. As the animation shows, in just over 2 minutes the car went from a safe temperature to an unsafe temperature of 94.3°F. This demonstration shows just how quickly a vehicle can become a death trap for a child.
The information contained in this circular was obtained from the Los Angeles Fire Department, the American Red Cross, Cedars-Sinai Medical Center, the Department of Aging, and the Department of Water and Power. The Department of Aging is distributing free copies of an emergency guide for individuals who want more information regarding heat wave emergencies. The Department of Aging has also established a toll free heat wave hotline. The telephone number is 800-339-6993.
The information in this circular is for helping individuals recognize incidents of overexposure to heat. However, if there is any doubt regarding person’s health or well being, immediate medical attention should be sought. If an emergency exists, immediately call 9-1-1 for assistance.
