Topline:

It's going from warm to hot across Southern California starting Tuesday, potentially reaching triple digits in a heat wave that will last through Friday.

What else should I know: Along with low humidity in the forecast, that means fire risks. Forecasters, however, say they don't expect high winds. The biggest danger for fire will be in the mountains.

When can I expect some relief: Temperatures are expected to cool down by the weekend. However, an extended heatwave could be in store for the interior mountains and the Antelope Valley into the following week.
