Stop Kirupa's Falling Snow

[COLOR=navy]Hi all![/COLOR]
[COLOR=navy]I am trying to find a way to stop the snow from Kirupa’s “Create[FONT=Verdana] Falling Snow” tutorial. When I change scenes in Flash I need the snow to have stopped. This is his tutorial that I used: http://www.kirupa.com/developer/mx/snow.htm[/FONT][/COLOR]

[COLOR=navy]Here is the action I am working with:[/COLOR]
[COLOR=navy][/COLOR]
[COLOR=navy]onClipEvent (unload) {
//specifies the size of the movie stage
movieWidth = 800;
movieHeight = 516;

//variables that will modify the falling snow
i = 1+Math.random()*2;
k = -Math.PI+Math.random()*Math.PI;

//giving each snowflake unique characteristics
this._xscale = this._yscale=50+Math.random()*100;
this._alpha = 75+Math.random()*100;
this._x = -10+Math.random()*movieWidth;
this._y = -10+Math.random()*movieHeight;
}
onClipEvent (enterFrame) {
//putting it all together
rad += (k/180)*Math.PI;
this._x -= Math.cos(rad);
this._y += i;
if (this._y>=movieHeight) {
this._y = -5;
}
if ((this._x>=movieWidth) || (this._x<=0)) {
this._x = -10+Math.random()*movieWidth;
this._y = -5;
}
}
