Narrative:
Lots of vectoring into psp (various other aircraft); we had an 8 mi; mid-field 45 degree left downwind entry for a visual into runway 13. Had requested/briefed and set up for an pnp to runway 13; but due to traffic...the wind was (from tower various directions/speeds) right down the mountain into our face turning from base to final. No LLWS alert/forecast/nor on ATIS; so we were the first to encounter it. It happened at 500 ft AGL as I was at +20 KIAS; so I elected to select flaps 30 degrees and continue to land (already had +10/flaps 40 degrees selected for the RNAV runway 13). The only problem (other than the blowback/it was logged and maintenance met the aircraft) was a hot brake which maintenance told us about when he met the aircraft. Beef up the B-900 flaps or fix the high landing speeds and beef up the brakes. Both seem to be on the weak side of safety. This would not have been a reportable event in the other B737's. With the already inflated B-900 landing speeds the (almost) mandatory 40 degree flap selection for landing an event such as this is a certainty! Any way to fix the problem...get stronger flaps; lower landing speeds; etc?

Title: B737-900 FLT CREW ENCOUNTERS LLWS AT 500 FEET AGL ON APPROACH TO PSP AND CONTINUES TO LAND WITH FLAPS RETRACTED TO 30 DEGREES.
Narrative: LOTS OF VECTORING INTO PSP (VARIOUS OTHER ACFT); WE HAD AN 8 MI; MID-FIELD 45 DEG L DOWNWIND ENTRY FOR A VISUAL INTO RWY 13. HAD REQUESTED/BRIEFED AND SET UP FOR AN PNP TO RWY 13; BUT DUE TO TFC...THE WIND WAS (FROM TWR VARIOUS DIRECTIONS/SPDS) RIGHT DOWN THE MOUNTAIN INTO OUR FACE TURNING FROM BASE TO FINAL. NO LLWS ALERT/FORECAST/NOR ON ATIS; SO WE WERE THE FIRST TO ENCOUNTER IT. IT HAPPENED AT 500 FT AGL AS I WAS AT +20 KIAS; SO I ELECTED TO SELECT FLAPS 30 DEGS AND CONTINUE TO LAND (ALREADY HAD +10/FLAPS 40 DEGS SELECTED FOR THE RNAV RWY 13). THE ONLY PROB (OTHER THAN THE BLOWBACK/IT WAS LOGGED AND MAINT MET THE ACFT) WAS A HOT BRAKE WHICH MAINT TOLD US ABOUT WHEN HE MET THE ACFT. BEEF UP THE B-900 FLAPS OR FIX THE HIGH LNDG SPDS AND BEEF UP THE BRAKES. BOTH SEEM TO BE ON THE WEAK SIDE OF SAFETY. THIS WOULD NOT HAVE BEEN A REPORTABLE EVENT IN THE OTHER B737'S. WITH THE ALREADY INFLATED B-900 LNDG SPDS THE (ALMOST) MANDATORY 40 DEG FLAP SELECTION FOR LNDG AN EVENT SUCH AS THIS IS A CERTAINTY! ANY WAY TO FIX THE PROB...GET STRONGER FLAPS; LOWER LNDG SPDS; ETC?
