* TEMPERATURES...High temperatures will range from 98 to 112 degrees through Friday. Low temperatures will be in the 70s to lower 80s...highest across the elevated and foothill locations.

* IMPACTS...The very high temperatures create a dangerous situation in which heat related illnesses are possible. Temperatures inside vehicles, even if the windows are partially open, can quickly rise to life-threatening levels. 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 911.
