Slat disagree alert appeared on extension. Intercepted localizer at 3;000 FT; descended to 2;000 FT as the First Officer was running ORH procedures. When it was evident that we needed more time for QRH procedures we requested vectors north of airport and to change runway due to the longer landing distance. On final; requested emergency equipment be dispatched to the taxiway near the departure end of runway in the event of brake overheat. We landed; turned left onto taxiway. After exiting the runway we requested the emergency personnel inspect brakes for smoke or fire; none reported. We taxied to gate with no further alerts. We were fortunate to have landed when we did because a [thunderstorm] rolled onto the field as we taxied to the gate.
MD-11 Captain reported leading edge slat disagree light on approach. Procedure was run and a normal landing ensued.
