2 TIMES A D328 SLID ON THE SANDED TXWY AS IT WXVANED INTO THE WIND. THE ACFT HAD TO BE TOWED INTO A NEW POS.

Narrative

AFTER CLRING THE RWY AND STOPPING; THE ACFT STARTED A SLOW TURN TO THE L; WHICH WE COULD NOT STOP. IT TURNED ABOUT 100 DEGS TO THE L BEFORE STOPPING. THE ACFT NOSEWHEEL WAS AT THE EDGE OF THE TXWY; THEREFORE; WE COULD NOT CONTINUE OUR TAXI AND HAD TO BE TOWED OUT. AT NO TIME DID WE LEAVE THE TXWY. AFTER WE DEPLANED OUR 1 PAX; WE HAD MAINT TURN THE ACFT THROUGH TOWING TO FACE THE RWY. THE TXWY; RWYS; AND THE RAMP WERE SANDED. WE STARTED THE ENGS AND FOLLOWED THE TRUCKS BACK TAXIING UP RWY 6; MADE A L ONTO SIERRA AND CONTINUED ONTO THE RAMP WHERE WE STOPPED; SET THE PARK BRAKE; AND AWAITED INSTRUCTIONS FROM THE ARPT OPS VEHICLES AS WHERE TO PARK. ONCE WE STOPPED; AGAIN THE ACFT STARTED A SLOW TURN TO THE L AND CAME TO A STOP. AFTER THIS OCCURRED; THE ARPT MGR CLOSED DOWN THE ARPT. I FEEL THE TXWY CONDITIONS (RPTED AS FAIR TO POOR) AS WELL AS THE WINDS CONTRIBUTED IN THE WXVANING OF THE ACFT (010 DEGS AT 22 KTS GUSTING TO 32 KTS). DUE TO THE FACT THAT THE TXWYS WERE SANDED THE SECOND TIME; I THINK THE WIND WAS THE GREATEST FACTOR. AT NO TIME DID THE ACFT LEAVE A SURFACE OR IMPACT ANYTHING.
