(Banning) -- You can tell summer is just around the corner.

All it takes is a day or two of warmer weather, some gusty wind, and some low humidity. And before you know it, flames are marching down a hillside in the direction of homes.

That's what happened in the hills north of Banning this morning.

This time, humans were responsible.  Four different fires started in separate places.  They broke out within minutes of each other in a canyon next to the San Gorgonio Memorial Cemetery.

That can only mean one thing:  arson.  Whoever did it got away, for now.  Investigators suspect "juvenile activity".

Soon, the fire was burning up against some backyards in the neighborhood down the hill.

And we saw the images that are familiar to everyone who lives in Southern California:  homeowners hosing down rooftops, blackened hillsides, trees burning, folks packing up their cars.

This time, firefighters attacked and won.

They kept it from damaging homes or hurting people

Next time, the result could be different.  I'm sure we'll back back on some hillside somewhere else countless times over the next few months covering other fires.

This morning's fire broke out in one of the windiest parts of Southern California.  The San Gorgonio Pass is west of Palm Springs.  It's where they have all those windmills that generate power.

But you know the really windy, really hot Santa Ana weather is still a few months off.  What happened this morning was just a preview.
