A July 4th weekend heat wave is moving into Southern California that will bring temperatures in some areas that could hit 110 degrees.

The National Weather Service issued heat warnings for large swaths of the region, warning people to avoid strenuous outdoor activities.

Inland valley areas will see the hottest temperatures. Officials said the San Fernando and San Gabriel valleys could hit the century mark and the Antelope Valley could see temperatures up to 110 degrees. Even the Hollywood Hills could see temperatures in the high 90s.

Beaches will be cooler, with temperatures in the 70s and 80s.

Inland Orange County should also get into the 90s.

Temperatures are not expected to cool until sometime next week.

Here is some information about dealing with heat that may come in handy this weekend:

Question: What are some tips for avoiding heat-related illnesses?

Answer: Drink plenty of water but avoid caffeine and alcohol, which cause fluid loss. Drink fruit juice or sports drinks to replace salt and minerals lost through sweat. Take advantage of shade and air conditioning. Children, the elderly and pets should never be left in an enclosed vehicle, even briefly. The temperature can quickly rise to life-threatening levels even with the windows partly open.

Q: Are certain people more susceptible to heat illness?

A: Many of those who have died of suspected heat-related causes were either elderly people or transients who could not find shelter from the heat.

Q: What is heat stroke?

A: The body gets so hot that the normal mechanisms for controlling temperature, such as perspiration, don't work well or fail completely. The body's temperature can rise to 106 or higher.

Q: What are the symptoms?

A: They include but are not limited to dizziness, hot and dry skin, high temperature, rapid pulse and headache.
