LOS ANGELES (KTLA) -- Triple digit temperatures are expected to continue across parts of Southern California through Thursday.
Temperatures are expected to top the 100 degree mark in the Antelope Valley and Inland Empire.
Temperatures are expected to cool down by Friday.
The low humidity, high temperatures and dry brush around the mountain regions raise fire concerns.
Residents living near brush areas should clear the brush around their homes and make sure they have an evacuation and emergency plan in place.
The hot and dry conditions associated with heat waves may also worsen air quality.
Cooling Centers Open in L.A. County
Cal Fire authorities warn that with a year of low rain fall, the 2012 fire season could be a dangerous one.
"We are looking at weather conditions and vegetation conditions that are extremely dry," said Cal Fire Director Ken Pimlott.
"We've had well-below average rainfall throughout much of California, particularly here in Southern California."
Officials warn that temperatures inside cars can soar up to 160 degrees on a hot day -- enough to cause heat stroke, permanent brain damage or even death in children or pets.
"Dogs and cats' normal temperatures are several degrees higher than those of humans," making them more susceptible to health issues from heat exposure, Ana Bustilloz of spcaLA warns.
LAFD offers a few tips to help beat the summer heat:
Adjust your attire and activities to limit heat exposure and exertion; Drink plenty of water before you become thirsty and rest in the shade before you become tired; If your home doesn't have air conditioning, find a cool place like a mall, theater, or local cooling center.
If you see a pet overheating in a locked car, take down the vehicle information and have the owner paged in nearby shops or contact the police immediately.
